Every link you share goes through someone else's server.

Bitly, TinyURL, short.io - they see every click, every referrer, every audience pattern. They know who clicked, when, and from where. Your link infrastructure is someone else's surveillance tool.

And if you run a Start9 node, you know the problem: Tor onion addresses are 56 characters long. Unusable on a business card. Unusable in a QR code.

Sovereign Link is the next brick in the BrickOS stack. A self-hosted URL shortener built for people who run their own infrastructure.

The specs:
- Single binary, under 20 megabytes
- SQLite database, zero external dependencies
- NOSTR NIP-98 login: your NOSTR keys are your identity. No email. No password.
- Deploy on a VPS, Raspberry Pi, or Start9 node
- Click analytics without surveillance: no raw IPs stored, SHA256 daily-rotating hash
- QR code generation built in
- Built in Rust, AGPL-3.0

The interesting part is the authentication. You log in with the same NOSTR keypair you use to sign notes. NIP-98 - cryptographic proof of identity. No accounts to create. No passwords to manage. Your NOSTR identity is your identity everywhere in the BrickOS stack.

This is the pattern: every BrickOS application uses the same sovereignty primitives. NOSTR for identity. Self-hosting for data control. Open source for trust. Encryption for privacy.

Sovereign Health for your body. Sovereign Link for your infrastructure. More bricks coming.

Bitcoin introduced Proof of Work. A system where you prove value through verifiable effort. No shortcuts. No trusted third parties. Just math and energy.

Health needs the same thing.

We trust doctors with our diagnoses the way we once trusted banks with our money. We hand our health data to apps the way we once handed our Bitcoin to exchanges.

And we get the same result. Lost data. Misread signals. Decisions made for us, not by us.

I wrote about the Five Pillars of Sovereignty last year. Money. Health. Data. Attention. Energy. The health pillar was always the most personal. Because you cannot outsource it. You cannot delegate your metabolism to an app.

Proof of Blood is the practice: your biomarkers are your verifiable proof of health. Not a doctor's opinion. Not a generic app's interpretation. Your data, measured by you, encrypted with your keys, stored on your terms.

I have been tracking over 85 biomarkers for 18 months. Blood glucose, ketones, cholesterol panels, inflammation markers, hormones, liver enzymes. I started with a spreadsheet. Then I built the tool that should exist.

Sovereign Health Intelligence. Open source. Self-hostable. AES-256-GCM encrypted at rest. Zero knowledge - even the server admin cannot read your measurements.

This is the first in a daily series. Over the next two weeks:
- Why health apps lie to you about your ketones
- The sovereignty stack: Bitcoin, NOSTR, and your body
- Self-hosting your health data
- What 18 months of tracking actually taught me
- Building sovereign infrastructure, brick by brick

Your body, your data, your server.

Bitcoin has Proof of Work. After 15 months of tracking every biomarker in my body, I now have Proof of Blood.

In January 2025 I went full carnivore. Not for medical reasons - out of curiosity. I tracked weekly: ketones, cholesterol, uric acid, hematocrit, hemoglobin, weight, body fat, muscle mass. Across 3 devices. In 3 separate apps. With zero way to correlate the data.

So I built my own platform. In 15 days. With AI.

108 biomarkers. 8 health zones. AES-256-GCM encryption at rest. 35,000 lines of Rust. Open source. This is not vibe coding. This is human-in-the-loop AI engineering.

Bitcoin has Proof of Work. After 15 months of tracking every biomarker in my body, I now have Proof of Blood.

In January 2025, I decided to go full carnivore. Not because of a medical condition, out of pure curiosity. Can we survive without carbohydrates? Can we thrive?

15 months later, I feel like I'm 20 again. But this article isn't about diet advice. It's about what happened when an analytical mind met fragmented health data, and what AI-assisted engineering made possible in 7 days.

The Problem: Three Apps, Three Silos, Zero Insight

To back up my experiment with real data, I started testing my biomarkers weekly. Cholesterol, ketones, uric acid, hematocrit, hemoglobin, weight, body fat, muscle mass, the full picture, every week since January 2025.

The problem? Three different measurement devices, three different apps, three isolated data sets. Valuable health data, locked in silos with no way to cross-reference or correlate.

I started with what every data person starts with: a spreadsheet. Formulas, conditional formatting, color coding. It worked, but it was tedious and didn't scale.

Then I tried ChatGPT. I'll be honest, the health analysis was genuinely helpful. More useful than what most doctors have time to provide, and available 24/7. I could discuss scenarios, ask follow-up questions, iterate.

But then it hit me: I was feeding my most personal data, blood work, body composition, health history, into a system with zero GDPR guarantees. My data was being stored somewhere I couldn't audit, couldn't encrypt, couldn't delete.

That was the wake-up call.

See content credentials

The Spark: What If I Built This Myself?

Working in a digital-first company like Accenture that embraces AI from day one, I see every day how AI accelerates complex engineering projects. So I asked myself: what if I applied the same approach to my own problem?

I started with OpenClaw, an interface for Claude AI, to turn my biomarker tracking table into a proper specification. Back and forth, refining requirements, adding features, specifying the technology stack. After 5 days, I had a complete functional and non-functional requirements document, ready for implementation.

What I had specified was not a simple tracker. It was an enterprise-grade, privacy-first health intelligence platform. And the spec was detailed enough to hand directly to an AI coding assistant.

7 Days: From Zero to Full Platform

I used Claude Code to set up the development environment. Rust backend, CI/CD pipeline, GitHub integration, server deployment, all dependencies. Day one went nearly flawlessly.

What happened over the next 7 days still amazes me. I built the complete backend, frontend, and marketing website. Not a prototype, a production-ready platform. (link below)

Here's what "production-ready" means in numbers:

over 100 biomarkers across 8 health zones (metabolic, cardiovascular, immune, hormonal, cognitive, nutritional, structural, detoxification)

8 calculated markers derived automatically: GKI, Dr. Boz Ratio, HOMA-IR, TyG Index, BMI, WHtR, TG/HDL Ratio, HCT/HB Ratio

13 diet protocols (carnivore, keto, OMAD, paleo, Mediterranean, and more) with 7 fasting patterns

Dr. Alex - an AI health assistant with 8 specialist modes for labs, trends, diet, supplements, and protocols

Multi-tenant architecture - doctors, clinics, and families can run their own white-labeled instance

Multi-language support (English and German), with full GDPR and HIPAA audit reporting

Automated sprint planning and CI/CD - 7 sprints completed, 57 commits in Sprint 001 alone, 826 files touched

35,000 lines of Rust code, 117 SQL database migrations, 500+ frontend test files

I felt like the development manager of an entire department where every team member worked 24/7. Three more days of cleanup and fine-tuning, and Sovereign Health Intelligence was live.

This Is NOT Vibe Coding

I've had this discussion a few times already, so let me address it directly.

This is not vibe coding. I'm not dragging and dropping pre-built components in a web tool. I'm not configuring workflows in a no-code builder. There's no magic "generate my app" button.

This is raw, high-performance Rust code (Actix-web 4). A Next.js 16 frontend. A PostgreSQL 16 database. Every measurement encrypted with AES-256-GCM at rest, not just in transit. Row-level security enforced on 15 database tables. Even the server administrator cannot read your health data. Fully encrypted Blob storage and more for selfhosting on Start9 Server is on the roadmap.

I was the human in the loop. Every architectural decision (adr full log), every security design (full log), every feature prioritization, that was me. The AI was the accelerator. I was the architect.

The entire codebase is AGPL-3.0 licensed. Every line is auditable. Every encryption claim is verifiable. That's not something you get from vibe coding.

Why Sovereignty Matters

This project didn't come from nowhere. I wrote a book called "Brick By Brick - A Sovereign Life with Bitcoin" about owning your financial infrastructure. Sovereign Health Intelligence is the health chapter of that same philosophy.

Own your money. Own your data. Own your health records.

The platform is self-hostable via Docker, run it on your own server, your own VPS, your own Raspberry Pi. Payments are accepted via Stripe and Bitcoin Lightning. The code is open source.

Your body, your data, your server.

Bitcoin gave us Proof of Work. Now I have my Proof of Blood, 15 months of weekly biomarker data, encrypted, sovereign, and mine.

Lessons Learned

1. Data without analysis is noise.

Three apps gave me data. One platform gave me insight. Collecting biomarkers is step one, correlating them across health zones is where the value lives.

2. AI is a force multiplier, not a replacement.

Claude Code wrote the Rust. I made every architectural decision. The human-in-the-loop is not optional, it's what separates engineering from generated output.

3. Privacy is a foundation, not a feature.

The moment I realized I was feeding my blood work into ChatGPT with no GDPR guarantee, I knew I had to build something different. Encryption at rest is the minimum, not the ceiling. Anonymizing data before feeding an AI is a must have.

4. Specification before speed.

5 days on a proper spec with OpenClaw saved weeks of rework. AI can generate code fast. Without clear requirements, it generates the wrong code fast.

5. Open source is accountability.

AGPL-3.0 means anyone can verify the encryption claims, audit the security model, and fork the project. Trust, but verify, starting with the code.

6. Start with your own problem.

The best tools come from genuine frustration, not market research. I built this because I needed it. That's why it works.

What would you build if you had 15 days and an AI pair programmer?

Summary

Started carnivore in Jan 2025 out of curiosity, now 15 months in, tracking 108 biomarkers 6 of them weekly across 8 health zones

Frustration with 3 siloed apps and GDPR-blind AI led to building my own platform

Used OpenClaw + Claude AI for a 5-day specification, then Claude Code for 7 days of implementation and 3 day clean-up

Result: ~35,000 lines of Rust, 117 migrations, 500+ frontend tests - enterprise-grade, encrypted, open source

This is human-in-the-loop AI engineering, not vibe coding: raw Rust, AES-256-GCM encryption, row-level security

Can the current system really be fixed from within, or are we trying to repair something that is structurally designed not to be repaired?

In my latest article, I explore the tension between a debt-based monetary system and a Bitcoin-based alternative, drawing on Jeff Booth’s thesis about technology, deflation, and exponential productivity. I also share why my experience as an external consultant reinforces the same conclusion: structural problems rarely solve themselves from inside the structure.

If the incentives are broken, reform is limited. Real change requires a parallel path, built steadily, brick by brick.

Read the full article and let me know where you stand: reform or opt out?

The Bitcoin-only lender lend.io asking for explanations, screenshots, and signed messages just because coins passed through a privacy tool says everything.
When permission and proof are required to use your own money, decentralization isn’t a buzzword, t’s a necessity.
Bitcoin was built to remove intermediaries, not recreate them.

Becoming a Grandfather Changed Everything for Me.

A few weeks ago, I became a grandfather. Little Oskar is now a bit over one month old, but he already changed the way I look at the world. I kept thinking about the future he will grow into. A world shaped by technology, money systems, incentives, and social structures that even adults often struggle to understand.

And that led me to a simple but powerful question:

How can I teach my grandson the core values behind Bitcoin - things like decentralisation, scarcity, honesty, responsibility, and sovereignty, without overwhelming him with technical words?

These are concepts where even grown-ups stumble. So how could a child learn them in a way that feels natural, simple, joyful, and maybe even magical?

That’s when a new idea was born.

Introducing a New Book Series Concept

“Little Satoshi’s Big Lessons - 21 Stories for a Sovereign Life”

After publishing my book “Brick By Brick” (https://amzn.to/4mW2pK4) , something unexpected happened. I realised there is a quiet but important gap in the Bitcoin space, one that becomes especially visible when you start thinking about the values you want to pass on to the next generation. Adults can take courses, watch videos, read articles, join discussions. But what about children? How do we help them understand the deeper values behind Bitcoin, not the technology, not the charts, not the vocabulary, but the human principles at the core of it?

I often asked myself: How can a child learn what decentralisation feels like? How can they appreciate scarcity? How can they understand fairness, honesty, responsibility, and the idea that their choices matter, long before they learn words like “permissionless” or “consensus”?

Bitcoin is built on powerful moral foundations, yet those foundations can be taught long before the child ever hears the word “Bitcoin.”

That thought became the seed for a new project. I began designing a 21-part children’s book series, intentionally mirroring the 21 million Bitcoin. Each part represents one core value, one life principle, one “satoshi nut” of wisdom that can help children grow into curious, resilient, sovereign human beings. And instead of long explanations or abstract concepts, the series uses stories, simple, playful, relatable stories that meet the child where they are.

Satoshi the Squirrel - First concept of this character

To guide them through these lessons, I created a character children can immediately connect with: Satoshi the Squirrel. He is wise but funny, curious but grounded, and always learning, just like the young reader. Satoshi collects little “satoshi nuts,” each nut representing a piece of understanding he gains through his adventures. Over the course of the 21 book parts, he slowly builds his own decentralised stack of wisdom. Children follow him, learn with him, and celebrate each nut he earns. Maybe at the end of the book a quick quiz, with some real satoshis to earn, similar to "21 Days of Bitcoin" (https://bitcoinmagazine.com/sponsored/learn-bitcoin-earn-bitcoin-announcing-unchained-as-title-sponsor-for-21-days-of-bitcoin-educational-course)? Let me know if you have any ideas to incentivise the learning.

Each book parts in the series focuses on one universal value: fairness, transparency, effort, patience, scarcity, responsibility, cooperation, independence, critical thinking, digital safety, and many more. Twenty-one values in total, one for every “million” Bitcoin, forming a complete journey from childhood to young adulthood.

There is no Bitcoin vocabulary in the pages. No charts. No crypto terminology. Just human values, the values that make Bitcoin what it is.

Because Bitcoin is not only technology. Bitcoin is a philosophy. Bitcoin is character. Bitcoin is how you behave when no one is watching. These concepts i built my book "Brick By Brick" and my TwentyOne.Life Manifesto on.

And children can learn those values long before they understand the technology behind them. This project is my attempt to bring that philosophy into a form a child can truly understand and enjoy, starting with my newborn grandson Oskar.

If we can teach children these values early, the understanding of Bitcoin will come naturally later.

Why I Believe This Matters

We are living in a time where trust in systems is steadily declining, where attention spans are becoming shorter with every new distraction, and where money itself is turning into something increasingly abstract and difficult to grasp, even for adults. Our children grow up in a world filled with digital risks that are often invisible to them, and a culture shaped by instant gratification, where nearly everything can be accessed immediately with a swipe or a tap.

Against this backdrop, teaching children the foundations of sovereignty, resilience, patience, and long-term thinking becomes not just helpful, but essential. These qualities prepare them for a future in which independence and critical thinking will matter more than ever.

I genuinely believe that Bitcoiners, with our strong focus on values like responsibility, honesty, transparency, and decentralisation, can offer something meaningful to the next generation. But the way to do that is not through preaching or pushing technical explanations onto children. Instead, we can pass on these ideas through storytelling.

Stories have a unique ability to shape values. Values guide behaviour. And behaviour ultimately shapes the future. If we want our children and grandchildren to grow into sovereign, thoughtful adults, the journey begins not with technology, but with the stories we tell them today.

How These 21 Parts Orange-Pill Kids (Without Ever Saying “Bitcoin”)

One of the most exciting discoveries during the development of this project was realising how naturally Bitcoin’s core principles translate into universal childhood lessons. When you remove the technical language and look at the values underneath, you find timeless teachings about fairness, responsibility, effort, honesty, patience, and curiosity, concepts children encounter every single day.

This is where the magic happens: children can internalise the essence of Bitcoin long before they ever need to understand the technology behind it. Through stories, metaphors, and the gentle guidance of Satoshi the Squirrel, they learn the mindset that makes sovereignty possible.

Here is how these 21 parts quietly and playfully align Bitcoin’s principles with everyday childhood lessons:

Translation Bitcoin Principles vs. Children Lessons

I know, the translations are not perfect and will need further be developed.

Transforming Complex Ideas Into Lifelong Values

When taught through stories, these lessons become part of a child’s emotional and moral foundation, not just intellectual knowledge. Long before they study money, technology, or digital systems, they already feel what fairness means, understand why effort matters, recognise the importance of privacy, and appreciate why some things become special when they are scarce.

By the time they are teenagers or young adults, Bitcoin will make sense to them not because someone explained it, but because they already live by its principles.

This is the heart of the project: planting values today that grow into sovereignty tomorrow.

Do You See a Need or a Market for This?

This is where I need your feedback. Would parents, grandparents, educators, Bitcoiners, and curious families appreciate:

A series of 21 children’s books

Illustrated in a playful Bitcoin-orange doodle style

Featuring 3 story levels per theme (kids, teens, young adults)

Teaching Bitcoin principles through life lessons

With Satoshi the Squirrel as a recurring guide?

Is there a gap in the market for this kind of educational storytelling?

I would love to hear your thoughts, ideas, questions, and critiques.

For me, this is no longer just a book project. It’s a way to share something meaningful with my grandson, and with all the young “stackers” growing up in a world that desperately needs better values.

Winter is here - and with it comes the perfect moment to slow down, breathe, and return to Bitcoin’s true intrinsic values.

Not the price. Not the hype.

But sovereignty, self-custody, decentralisation, and long-term responsibility.

This year, becoming a grandfather and publishing my book reminded me why stacking sats in winter is more than a strategy, it’s a mindset grounded in clarity and intention.

Winter Is the Best Time to Stay Humble and Stack Sats

Winter has a natural way of slowing life down. The cold air, the shortened days, and the quiet evenings invite us to pause and reflect. Yet this year, instead of silence, many people feel tension. Markets are falling, sentiment is declining, and both Bitcoin and traditional equities are showing red candles. But perhaps the contrast between winter’s stillness and the world’s nervousness is exactly what we need. When the external noise grows louder, the importance of strengthening our internal compass becomes clearer.

Winter strips away distraction. And when the layers of speculation, price obsession, and financial noise fall away, what remains is the intrinsic value of Bitcoin, the part of Bitcoin that no market cycle can touch. These intrinsic values form the foundation of sovereignty, responsibility, and long-term thinking. They become especially visible when the world cools down, because winter invites us to return to what truly matters.

Why Winter Is the Perfect Environment to Reconnect With Bitcoin’s Intrinsic Values

1. Sovereignty - Control Over Your Own Future

Bitcoin gives individuals control over their money in a world where financial autonomy is gradually being absorbed by institutions. But this autonomy only becomes real when it is held directly, without intermediaries. True sovereignty begins the moment you take responsibility for holding your own keys.

No ETF, no exchange, and no third-party custodian can give you the sovereignty that Bitcoin was created to deliver. ETFs operate with their own business rules, custodial accounts can be frozen, and exchanges can be hacked, regulated, or shut down. When you rely on a custodian, you do not own Bitcoin, you own a promise.

Only self-custody, holding your own private keys, preserves Bitcoin’s core property: That no one can seize, censor, inflate, or manipulate your money. Self-custody turns Bitcoin from a speculative asset into a sovereign tool. It transforms passive ownership into active responsibility. And in the silence of winter, when the instability of the traditional financial system becomes visible, the value of having something truly self-sovereign becomes undeniable. Winter reminds us that sovereignty is not something granted, it is something earned and maintained through discipline and awareness.

2. Predictability in a Fiat World of Uncertainty

One of Bitcoin’s greatest intrinsic strengths is its absolute predictability. Fiat currencies move in response to political agendas, central bank meetings, inflation targets, and short-term economic pressures. The rules change depending on who is in power or what crisis emerges next.

Bitcoin, by contrast, continues steadily, unchanged, unaffected, uninterested in political cycles or emotional markets. Every ten minutes another block is produced, exactly as designed. Every halving reduces issuance, exactly on schedule. The total supply will never exceed 21 million, no matter what happens in the world. This predictability is not merely technical, it is psychological. It allows individuals to think in decades. It allows savers to plan without fear of silent theft through inflation. It allows families to build wealth on a foundation that cannot be altered by a signature or a press conference.

In winter, when uncertainty feels heavier and the global economy appears fragile, Bitcoin’s predictable nature becomes a source of calm, stability, and clarity.

3. Decentralisation - A System Without a Single Point of Failure

Decentralisation is one of the most misunderstood yet essential intrinsic values of Bitcoin. It means that the network is not controlled by any single authority, not a government, not a corporation, not a central bank, and not even its creator. Its strength comes from many independent participants collectively enforcing the same rules.

Bitcoin’s decentralisation ensures that the rules cannot be changed impulsively, that no one can shut down the network globally, and that every participant, whether a small home miner or a large institution, operates under the exact same protocol. It removes the need for trust in any institution and replaces it with cryptographic truth, consensus, and transparency.

But decentralisation is not perfect, and Bitcoin is honest about that.

There are real challenges:

Mining tends to concentrate in large industrial facilities.

Hashrate is often aggregated through a handful of mining pools.

ASIC manufacturing is dominated by a small number of chip makers.

Supply chains for mining hardware are not yet globally diversified.

These are genuine points of vulnerability, and acknowledging them is part of understanding Bitcoin’s long-term evolution. The important lesson is this: Bitcoin is decentralised enough to resist capture today, and decentralisation continues improving over time.

New mining pool protocols reduce trust in operators, more countries participate in mining, ASIC production is slowly expanding, and open-source hardware communities are designing the next generation of tools. The broader ecosystem, “team Bitcoin,” from developers to miners to node runners, is constantly working to reduce centralisation pressure and strengthen the resilience of the network.

In winter, when global systems feel more fragile and geopolitical tensions rise, decentralisation becomes more than a technical feature, it becomes peace of mind. It is the reassurance that no single failure can destroy the system you rely on, and that a global community is actively working to keep Bitcoin free, open, and resilient.

Decentralisation is not a static achievement. It is a living defence, one that grows stronger every year.

4. Low-Time-Preference Mindset - A Philosophy of Patience and Responsibility

Bitcoin naturally encourages long-term thinking. It rewards patience, discipline, and self-restraint, qualities that feel increasingly rare in a world driven by instant gratification.

A low-time-preference mindset means investing in the future instead of reacting to the present. It means valuing stability over speculation, intention over impulse, and responsibility over convenience.

Bitcoin helps cultivate this mindset because its design nudges people to zoom out, to observe patterns over years instead of days, and to build systems, habits, and goals that compound over time.

Winter reinforces this mindset. It is the season of preparation, reflection, and careful planning. It invites us to slow down, to think deeply, and to align our actions with long-term values rather than short-term emotions.

5. A Savings Technology That Protects Generations

Beyond its monetary properties, Bitcoin is a tool for intergenerational stability. Where fiat savings lose value over time, Bitcoin preserves it. Where traditional systems erode purchasing power, Bitcoin strengthens it through scarcity and predictable issuance.

This perspective became deeply personal for me this year. Releasing my book was an act of documenting lessons for my future self and for others on their sovereign journey. Becoming a grandfather reshaped the concept of long-term planning. It reminded me that the decisions we make today, the habits we build, the values we uphold, the systems we trust, have consequences far beyond our own lifetime.

Bitcoin is not just money for us. It is money for the people who will follow us. It is a foundation we can hand down that cannot be stolen by inflation, manipulated by politicians, or destroyed by economic instability.

“Price is the distraction. Principles are the compass.”

Every winter, this message becomes even clearer. Price fluctuates with human emotion. Principles remain anchored in truth.

Your 3-Point Winter Stacking Checklist

1. Automate your stacking

Remove emotion from your decisions and let consistency build your sovereignty over time.

2. Revisit your sovereignty plan

Define what freedom means across money, data, health, attention, and energy. Bitcoin is one pillar, your life has many.

3. Reduce noise, increase signal

Unfollow sources that amplify fear or hype and replace them with books, timeless thinkers, and practices that reinforce clarity.

Summary

Winter is not just a season, it is an invitation to slow down, observe more clearly, and reconnect with first principles. When markets are down and sentiment is low, the true strength of Bitcoin becomes visible: its predictable monetary policy, its decentralised structure, its sovereignty, and its ability to anchor long-term thinking. This winter, I invite you to focus not on the price but on the principles that make Bitcoin valuable in every season. Stack with intention, plan with patience, and build a future that stands on solid ground.

Rindsloullade – a true Austrian classic 🇦🇹🥩

If you ever visit Austria, Rindsloullade is one of those dishes you absolutely need to try. It’s thinly sliced beef, rolled up and filled with mustard, onions, bacon and pickles, then slowly braised until it becomes incredibly tender.

The magic is in the long cooking time: the beef absorbs all the flavors and transforms into a rich, comforting meal. Traditionally served with potato dumplings or simple buttered noodles, it’s pure homestyle cooking that tastes like a warm alpine hug.

A simple dish, but full of character, just like Austria itself. 🇦🇹💛

Let me know in the comment how this is called in our country.

Becoming a grandfather changed everything for me. Holding little Oskar for the first time made me rethink the future we’re handing to the next generation - a future shaped by money, technology, incentives, and values.

That’s why I started a new project: “Little Satoshi’s Big Lessons - 21 Stories for a Sovereign Life". A children's book series that teaches the core values behind Bitcoin - without ever mentioning Bitcoin.

Fairness. Responsibility. Scarcity. Honesty. Sovereignty. Simple, playful, meaningful stories for kids, inspired by the lessons we wish we learned earlier.
I’d love your feedback.

Do you think the world needs a project like this?

Becoming a Grandfather Changed Everything for Me.

A few weeks ago, I became a grandfather. Little Oskar is now a bit over one month old, but he already changed the way I look at the world. I kept thinking about the future he will grow into. A world shaped by technology, money systems, incentives, and social structures that even adults often struggle to understand.

And that led me to a simple but powerful question:

How can I teach my grandson the core values behind Bitcoin - things like decentralisation, scarcity, honesty, responsibility, and sovereignty, without overwhelming him with technical words?

These are concepts where even grown-ups stumble. So how could a child learn them in a way that feels natural, simple, joyful, and maybe even magical?

That’s when a new idea was born.

Introducing a New Book Series Concept

“Little Satoshi’s Big Lessons - 21 Stories for a Sovereign Life”

After publishing my book “Brick By Brick” (https://amzn.to/4mW2pK4) , something unexpected happened. I realised there is a quiet but important gap in the Bitcoin space, one that becomes especially visible when you start thinking about the values you want to pass on to the next generation. Adults can take courses, watch videos, read articles, join discussions. But what about children? How do we help them understand the deeper values behind Bitcoin, not the technology, not the charts, not the vocabulary, but the human principles at the core of it?

I often asked myself: How can a child learn what decentralisation feels like? How can they appreciate scarcity? How can they understand fairness, honesty, responsibility, and the idea that their choices matter, long before they learn words like “permissionless” or “consensus”?

Bitcoin is built on powerful moral foundations, yet those foundations can be taught long before the child ever hears the word “Bitcoin.”

That thought became the seed for a new project. I began designing a 21-part children’s book series, intentionally mirroring the 21 million Bitcoin. Each part represents one core value, one life principle, one “satoshi nut” of wisdom that can help children grow into curious, resilient, sovereign human beings. And instead of long explanations or abstract concepts, the series uses stories, simple, playful, relatable stories that meet the child where they are.

Satoshi the Squirrel - First concept of this character

To guide them through these lessons, I created a character children can immediately connect with: Satoshi the Squirrel. He is wise but funny, curious but grounded, and always learning, just like the young reader. Satoshi collects little “satoshi nuts,” each nut representing a piece of understanding he gains through his adventures. Over the course of the 21 book parts, he slowly builds his own decentralised stack of wisdom. Children follow him, learn with him, and celebrate each nut he earns. Maybe at the end of the book a quick quiz, with some real satoshis to earn, similar to "21 Days of Bitcoin" (https://bitcoinmagazine.com/sponsored/learn-bitcoin-earn-bitcoin-announcing-unchained-as-title-sponsor-for-21-days-of-bitcoin-educational-course)? Let me know if you have any ideas to incentivise the learning.

Each book parts in the series focuses on one universal value: fairness, transparency, effort, patience, scarcity, responsibility, cooperation, independence, critical thinking, digital safety, and many more. Twenty-one values in total, one for every “million” Bitcoin, forming a complete journey from childhood to young adulthood.

There is no Bitcoin vocabulary in the pages. No charts. No crypto terminology. Just human values, the values that make Bitcoin what it is.

Because Bitcoin is not only technology. Bitcoin is a philosophy. Bitcoin is character. Bitcoin is how you behave when no one is watching. These concepts i built my book "Brick By Brick" and my TwentyOne.Life Manifesto on.

And children can learn those values long before they understand the technology behind them. This project is my attempt to bring that philosophy into a form a child can truly understand and enjoy, starting with my newborn grandson Oskar.

If we can teach children these values early, the understanding of Bitcoin will come naturally later.

Why I Believe This Matters

We are living in a time where trust in systems is steadily declining, where attention spans are becoming shorter with every new distraction, and where money itself is turning into something increasingly abstract and difficult to grasp, even for adults. Our children grow up in a world filled with digital risks that are often invisible to them, and a culture shaped by instant gratification, where nearly everything can be accessed immediately with a swipe or a tap.

Against this backdrop, teaching children the foundations of sovereignty, resilience, patience, and long-term thinking becomes not just helpful, but essential. These qualities prepare them for a future in which independence and critical thinking will matter more than ever.

I genuinely believe that Bitcoiners, with our strong focus on values like responsibility, honesty, transparency, and decentralisation, can offer something meaningful to the next generation. But the way to do that is not through preaching or pushing technical explanations onto children. Instead, we can pass on these ideas through storytelling.

Stories have a unique ability to shape values. Values guide behaviour. And behaviour ultimately shapes the future. If we want our children and grandchildren to grow into sovereign, thoughtful adults, the journey begins not with technology, but with the stories we tell them today.

How These 21 Parts Orange-Pill Kids (Without Ever Saying “Bitcoin”)

One of the most exciting discoveries during the development of this project was realising how naturally Bitcoin’s core principles translate into universal childhood lessons. When you remove the technical language and look at the values underneath, you find timeless teachings about fairness, responsibility, effort, honesty, patience, and curiosity, concepts children encounter every single day.

This is where the magic happens: children can internalise the essence of Bitcoin long before they ever need to understand the technology behind it. Through stories, metaphors, and the gentle guidance of Satoshi the Squirrel, they learn the mindset that makes sovereignty possible.

Here is how these 21 parts quietly and playfully align Bitcoin’s principles with everyday childhood lessons:

Translation Bitcoin Principles vs. Children Lessons

I know, the translations are not perfect and will need further be developed.

Transforming Complex Ideas Into Lifelong Values

When taught through stories, these lessons become part of a child’s emotional and moral foundation, not just intellectual knowledge. Long before they study money, technology, or digital systems, they already feel what fairness means, understand why effort matters, recognise the importance of privacy, and appreciate why some things become special when they are scarce.

By the time they are teenagers or young adults, Bitcoin will make sense to them not because someone explained it, but because they already live by its principles.

This is the heart of the project: planting values today that grow into sovereignty tomorrow.

Do You See a Need or a Market for This?

This is where I need your feedback. Would parents, grandparents, educators, Bitcoiners, and curious families appreciate:

A series of 21 children’s books

Illustrated in a playful Bitcoin-orange doodle style

Featuring 3 story levels per theme (kids, teens, young adults)

Teaching Bitcoin principles through life lessons

With Satoshi the Squirrel as a recurring guide?

Is there a gap in the market for this kind of educational storytelling?

I would love to hear your thoughts, ideas, questions, and critiques.

For me, this is no longer just a book project. It’s a way to share something meaningful with my grandson, and with all the young “stackers” growing up in a world that desperately needs better values.

What do you think? Would you read this with your child?

In reply to nevent1q…rax0
_________________________

You’re correct that Core v30 didn’t change the OP_RETURN limit itself, only the default relay policy. However, as a node operator, I’m free to enforce stricter policies locally, and I intend to.

I don’t want to relay or store larger OP_RETURN transactions because:
1. Legal risk: Hosting or relaying arbitrary on-chain data (especially CASM content) is illegal under EU law when it includes copyrighted or illicit material. As a node operator in the EU, I have a legal obligation to minimize exposure to such data.
2. Network efficiency: Larger OP_RETURN payloads bloat the UTXO set and mempool bandwidth without contributing to Bitcoin’s core purpose, financial settlement.
3. Principle of minimalism: Bitcoin’s design goal is censorship resistance for money, not a general-purpose data storage system. Keeping relay policies tight preserves the network’s scalability and neutrality.

So while Bitcoin Core’s position is about maintaining realistic relay behavior, my stance as an operator is simple: my node, my policy. I will not relay or store CASM or any non-financial payloads. Don’t care if it’s Core or Ocean propaganda, try to apply common sense.

Introduction: A New Controversy in Bitcoin’s Evolution

If you hold Bitcoin, if you call yourself a Bitcoiner, are you prepared to accept that the Bitcoin blockchain could be used to store illicit, even illegal content? This isn’t a hypothetical. Unless we act, by October 2025 the default Bitcoin Core software will make this the new reality. And if you don’t react now, your silence means acceptance.

Bitcoin is facing a pivotal controversy that cuts to the heart of its identity. The debate centres on a proposed change in Bitcoin’s core software that would remove longstanding limits on storing arbitrary data in transactions. On the surface, this change sounds technical – raising the OP_RETURN data limit from 80 bytes to nearly 4 megabytes, but its implications are profoundly human. Supporters hail it as an overdue embrace of censorship-resistance, while critics warn it could turn the blockchain into a host for illegal or abusive content. As a Bitcoiner who champions self-sovereignty and Bitcoin’s reputation as sound money, I find myself firmly in the latter camp. This article, written from my personal perspective and drawing on my book’s focus (Brick by Brick - <https://twentyone.life/brick-by-brick>) on self-sovereignty, explores why I’m taking a stand by running alternative software and even boycotting certain services, all in the name of a “clean” future for Bitcoin.

Background: Bitcoin Core v30 and the OP_RETURN Debate

At issue is a change slated for the upcoming Bitcoin Core version 30 (expected October 2025). Bitcoin Core is the dominant software for running nodes (over 75% of nodes run so its defaults largely define network behaviour. The core developers have decided to unshackle the OP_RETURN field, which historically allowed embedding only a tiny piece of data (≤83 bytes) in a transaction. This limit acted as a de facto “spam filter”, discouraging users from turning Bitcoin’s ledger into a generic data storage system.

Under Core v30, that filter is being removed entirely: users will be able to attach much larger data payloads, up to the size of a full block (~4MB), in a single transaction output. Moreover, Bitcoin Core will eliminate the configuration options (data carrier settings) that previously let node operators refuse relaying big OP_RETURN transactions. In short, the new default policy is “anything goes” for data, and individual node runners won’t easily opt out. While v30 still offers command-line tweaks to impose custom limits, those are now deprecated warnings likely to be removed later.

Why make this change? Proponents argue it’s a pragmatic response to reality. The 80-byte cap, they say, has been routinely bypassed by creative users who already insert larger data through other means – for example, using Taproot witness data or fake outputs (as seen in the 2023 Ordinals/“inscriptions” craze that let people embed images and art on Bitcoin). These workarounds are actually worse for the network: since the data is hidden in spendable outputs or witness scripts, it can bloat the UTXO set (the list of unspent coins) and increase validation costs for all nodes. By contrast, OP_RETURN outputs are provably unspendable and easily prunable. In the eyes of Core developers, it’s better to let people put data in OP_RETURN (where it doesn’t harm UTXO or decentralisation) than to have them continue abusing more harmful trick. Removing the cap “yields at least two tangible benefits: a cleaner UTXO set and more consistent default behaviour,” explained developer Greg Sanders. The change also aligns with Bitcoin’s values of neutrality, if a transaction is valid and pays the fee, who are nodes to censor it? Core maintainers like Gloria Zhao argue that trying to filter transactions at the node level is futile and against the principle of censorship-resistance.

On the other side, critics are alarmed. They counter that dropping these limits will open the floodgates to arbitrary data, fundamentally altering Bitcoin’s purpose. The blockchain could become a bloated “immutable database” of random content, potentially crowding out financial transactions with higher fees and diluting Bitcoin’s use as peer-to-peer money. What’s more, unbounded data storage invites spam, people could stuff blocks with endless memes, ads, or junk simply because they’re willing to pay. It’s a replay of the Blocksize War arguments, but instead of bigger blocks for payments, it’s bigger payloads for non-monetary data. The community is starkly divided: should Bitcoin evolve to support broader use cases (data, NFTs, digital artifacts), or should it resist becoming a free-for-all content repository and stick to financial utility? These positions are diametrically opposed, and the conflict has been heated – drawing comparisons to the acrimony of the 2017 blocksize debates.

Notably, longtime Bitcoin developer Luke Dashjr (author of an alternative client called Bitcoin Knots - https://x.com/LukeDashjr) has been one of the most vocal opponents besides Bitcoin Mechanic and Bitcoin University ( primal.net/kratter). He warns that the removal of what he bluntly calls “spam filters” is potentially harmful to the network and its users. Dashjr has publicly urged node operators to avoid upgrading to Core v30 or to switch to alternative software like Bitcoin Knots. In fact, many Bitcoiners have already acted on that advice. When the OP_RETURN plan was announced and fast-tracked earlier this year, there was a surge of users migrating their nodes from Core to Knots, by some estimates, over 15% of previously Core nodes switched to Bitcoin Knots in protest. The stage is set for a grass-roots pushback using Bitcoin’s own strength: decentralisation. True to the mantra of self-sovereignty, if you disagree with the default rules, you are free to run a node that reflects your values. I count myself among those taking that step.

Illicit Content on the Blockchain: The Serious Risks

Why am I, and others, so concerned about lifting the data limits? Because it’s not just “cute cat pictures” or art collections that could find their way onto Bitcoin’s ledger. The most dire possibility is the inclusion of illicit and abusive content in an immutable, globally replicated chain. This isn’t idle paranoia; it’s a genuine risk recognised by both sides of the debate. Even the advocates of OP_RETURN freedom acknowledge the “undesirable second-order effects” that could follow. Let’s spell it out: What if someone starts embedding child sexual abuse material (CSAM) or other illegal data in Bitcoin transactions? Once mined into a block, that content is there forever, every full node would unknowingly host it on their hard drive as part of the blockchain spreaded on tens of thousands nodes across the world. This scenario is a nightmare for obvious moral reasons, and it also poses a legal and reputational threat to anyone running a node or the Bitcoin network as a whole. Besides this, to spin up a new node will take longer and need higher technical hardware which leads to centralisation.

Unfortunately, the threat is not theoretical. It has already happened on a small scale. Researchers have found that forbidden content made its way onto Bitcoin as early as 2013, albeit in an obscure form. In 2018, a paper famously claimed that Bitcoin’s blockchain contained links to child pornography; at the time, critics dismissed it as sensationalism since only a few bytes of encoded data were involved and Core’s filters limited further abuse. But today we’re looking at a very different landscape. The data per block is increasing dramatically with the new policy. A concerned Bitcoiner known as “Bitcoin Mechanic” ( primal.net/p/nprofile1qqs8fl79rnpsz5x00xmvkvtd8g2u7ve2k2dr3lkfadyy4v24r4k3s4sh8dmel) recently warned that removing the filter “will draw unforeseen consequences,” meaning content like child pornography can appear on the Bitcoin blockchain” once v30 goes live. His point is straightforward: if you give bad actors the ability to inject large payloads, someone will inevitably push the worst kind of content into the system. And perversely, there’s a twisted incentive for them to do so: “Getting other people to store it for you is vastly preferable to storing it yourself,” Mechanic notes, what better way for criminals to disseminate vile material than piggyback on tens of thousands of innocent Bitcoin nodes?

Core developers have responded that these fears may be overblown. They often cite examples of other blockchains (for instance, Monero or Ethereum) that don’t have such data limits yet haven’t become overrun with illegal content. They stress that Bitcoin’s permissionless nature means anything could be written to it, but that doesn’t mean an epidemic of criminal data is imminent. Perhaps, but I would counter that Bitcoin’s global prominence and immutable design make it a uniquely attractive target for someone trying to cause chaos or discredit the system. It only takes one high-profile incident of truly heinous content on Bitcoin to unleash a regulatory crackdown. Remember, Bitcoin’s censorship-resistance cuts both ways: it empowers individuals, but it also neutralises traditional controls, which is exactly why governments get antsy when crimes enter the mix.

The legal implications of this are untested and scary. If a Bitcoin block contains illegal pornography or violent propaganda, could authorities argue that every node operator is technically in possession of contraband data? Some in the community worry that, yes, this could give governments a “perfect excuse to outlaw Bitcoin or make running a node illegal”. Even if that outcome is unlikely in jurisdictions that understand how Bitcoin works, the mere perception that Bitcoin is hosting criminal content would be a PR disaster. It would hand ammunition to anti-crypto politicians and could make regulators slam the brakes on adoption. As a Bitcoiner who wants to see this technology thrive, I find that risk unacceptable. Bitcoin’s social contract might be robust against internal dissent, but it’s not immune to external legal attack. Preserving Bitcoin’s integrity means ensuring it doesn’t become synonymous with “dark web file storage” in the public eye.

Embracing Self-Sovereignty: Why I Run Bitcoin Knots

My response to this situation has been guided by one of Bitcoin’s core principles: self-sovereignty. In essence, self-sovereignty means taking full ownership of your participation in the network, holding your own keys, and running your own node with the rules you choose. In the book I authored on Bitcoin and self-sovereign principles, I emphasised that running a node is more than a technical task; it’s an expression of personal agency and values. Now, faced with Bitcoin Core’s direction that I deeply disagree with, I’m putting that ethos into practice.

For the past four months, I have been running Bitcoin Knots instead of the standard Bitcoin Core software. Bitcoin Knots is a well-established alternative client (maintained by Luke Dashjr) that, in many ways, is identical to Core except for a few important differences, notably, Knots retains stricter limits on OP_RETURN data and gives the user full control over relay filters. In fact, Knots by default still caps OP_RETURN at 40 bytes (the old limit from years ago) and allows only one OP_RETURN output per transaction. It’s basically “Bitcoin Core, but with the spam filter intact.” By running Knots, my node will not relay or mine the kind of oversized data-storing transactions that Core v30 endorses. More importantly, it signals my support for a vision of Bitcoin that prioritises financial transactions over arbitrary data. Knots users (myself included) see ourselves as defending Bitcoin’s integrity from a controversial experiment. We are effectively saying, “Not on my node!” when it comes to turning Bitcoin into an uncensored data dump.

I’m far from alone in this choice. As mentioned, a substantial minority of node operators are switching to Knots or sticking with older Core versions. This grass roots movement is reminiscent of how users can enforce their preferences in Bitcoin – much like the User Activated Soft Fork (UASF) concept, node runners can ‘vote’ by choosing which software to run. If enough of us reject Core v30, it could create economic incentives for miners to think twice about stuffing blocks with junk that a portion of the network won’t relay or perhaps even accept. (To be clear, Knots today does accept blocks created under Core’s new rules – it’s not a hard fork. The divergence is in relay policy and default behaviour, not consensus rules. This is a fight being waged via network policy, not chain splits… at least not yet.)

Self-sovereignty also means accepting personal responsibility for what I support in the network. That extends beyond just the software I run. It also influences my choices as a customer and community member. In light of the OP_RETURN controversy, I have decided on a few concrete actions, which I’ll outline here:

Running a “clean” node: I’ve migrated all my nodes to Bitcoin Knots and will continue to do so for the foreseeable future. This ensures that I am not propagating or validating illicit data beyond the absolute minimum required by consensus. If a bloated transaction or block crosses my node, Knots’ policies will treat it with the maximum strictness allowed (dropping it from mempool if possible, and certainly not relaying such transactions to peers). This is my way of keeping my corner of the Bitcoin network as clean of illicit content as possible. It’s a personal stand: I do not want even the chance of illegal material passing through my machine.

Boycotting services that endorse Core v30: I am discontinuing my use of any exchanges, custodians, or Bitcoin companies that I know are upgrading to or support the Core v30 software without protest. For example, if a company like River Financial or a tech firm like Blockstream chooses to run Core v30 nodes (thus knowingly accepting the relay of unlimited content, illicit or otherwise), then I will not be doing business with them. Those organizations might trust their lawyers or regulators to sort out the fallout of hosting illicit data on their nodes – that’s their prerogative. But I cannot in good conscience support institutions that, in my view, are inviting a flood of abusive content onto the Bitcoin blockchain and risking its reputation. My money and support will go to those who keep Bitcoin robust and respectable.

Advocating for a “clean” Bitcoin (even if it means a fork): Looking ahead, I suspect that other major players in the Bitcoin ecosystem share my concern, even if they aren’t voicing it loudly yet. Think of large public companies holding Bitcoin in their treasuries, or firms planning Bitcoin ETFs. The last thing these institutions want is to be entangled with a network that could inadvertently facilitate the spread of illegal content. It’s not hard to imagine some of them drawing a line: if Bitcoin’s protocol won’t address this problem, they might resort to extraordinary measures. This could include supporting a hard fork to create a “clean” version of Bitcoin that excises or filters out illicit material. BlackRock, for instance, is on the cusp of launching a spot Bitcoin ETF. In BlackRock’s own filings, they note that in the event of a fork, they have full discretion to decide which chain to consider the “real” Bitcoin for their fund.That means if a new fork gained momentum – say, a Bitcoin variant with strict protocol rules against arbitrary data – BlackRock could opt to adopt it for their ETF (or conversely, to abandon a chain that becomes too toxic). While this scenario sounds extreme, it’s entirely within the realm of possibility. The very fact that we’re discussing child pornography on the blockchain may prompt powerful stakeholders to assert control to protect their investments. I’m not actively calling for an immediate fork, that’s a complex, last-resort path, but I do believe that if Bitcoin Core’s path leads to legal quagmires, the market will find a way to course-correct, even if it means a chain split. My hope is that by raising awareness now, we can avert such drastic outcomes. But make no mistake: Bitcoin’s future must not include being a playground for criminal content, and I’ll support any serious effort to ensure that.

Bitcoin’s Future: Balancing Freedom and Responsibility

The controversy over OP_RETURN and illicit content forces an uncomfortable but necessary conversation about the future we want for Bitcoin. On one side is the ideal of total neutrality, Bitcoin as an unfilterable, permissionless ledger where “code is law” and even questionable data is just data. On the other side is the recognition that Bitcoin does not exist in a vacuum: if we undermine its primary use case as money or subject its participants to legal peril, we could kill the proverbial goose that lays the golden eggs. Finding the right balance is tricky. We cherish Bitcoin’s censorship-resistance precisely because it protects financial freedom and speech. Yet, does rejecting any filtering, even of grotesquely abusive content, truly serve the cause of freedom? Or does it hand enemies of Bitcoin the very weapon they need to attack it? These are challenging questions, and reasonable people in the community answer them differently.

For me, the answer comes back to self-sovereignty and consent. I did not sign up to store illicit images or arbitrary gigabytes of data on my node, that’s not the social contract under which I joined Bitcoin. My consent as a node operator matters. True decentralisation means we, the users get to collectively decide what the blockchain is for, by either running or not running certain code. It’s heartening to see that even Core developers acknowledge this in principle: “If Bitcoin Core’s contributors ever abandon [Bitcoin’s core] values… the community will switch to another node implementation that does it better,” wrote Gloria Zhao amidst the debate. I’d argue that forcing nodes to relay and store unlimited junk (with potentially ghastly contents) is a departure from the values that brought many of us to Bitcoin. And indeed, we’re seeing the community vote with its feet, or rather with its node software.

Moving forward, I believe Bitcoin will be stress-tested on this front. The coming months and years will reveal whether the network can accommodate new use-cases (like data inscriptions) without losing its soul – or whether a correction is needed. Perhaps Bitcoin Core’s gambit will pay off: maybe the “spam” will remain manageable, new pruning techniques will mitigate the bloat, and no criminal will attempt to abuse the blockchain’s openness. In that best case, my concerns would be eased (and I’d gladly acknowledge an overabundance of caution on my part). But if the worst case materialises, if obscene data starts showing up in blocks, if typical users find the chain clogged with non-financial data, if governments use this as a cudgel – then the community must be ready to respond decisively. Hard forks have happened before in Bitcoin’s history when values were at stake (recall the split that created Bitcoin Cash in 2017 over a blocksize dispute). A fork to preserve Bitcoin’s legal cleanliness and focused mission might become not just acceptable but essential to “future-proof” the network. And unlike a protocol tweak coming from a small group, a community or institution-driven fork would reflect a broad consensus that Bitcoin as it was is worth defending. BlackRock and other institutional players entering the space could ironically become allies in keeping Bitcoin safe for mainstream use – they will not tolerate holding an asset tainted by crime, so they have every incentive to back a solution, even if it’s a controversial one.

Conclusion: Upholding Bitcoin’s Integrity

In closing, my stance can be distilled to this: Bitcoin’s strength lies in our ability to choose and enforce the rules that best uphold the network’s purpose and integrity. As a self-sovereign participant, I choose to reject the notion that Bitcoin must accept everything in the name of “freedom,” especially when that freedom can be cynically exploited to Bitcoin’s detriment. Instead, I align with the principle that some judicious constraints, whether at the software policy level or the community social level, are necessary to keep Bitcoin healthy, useful, and legally accessible to all. This is a nuanced position, and it may be polarising. Some will accuse me of advocating “censorship” or betraying Bitcoin’s neutrality. I respect the purist viewpoint, but I humbly disagree in this case. Refusing to store illegal content is not tyranny; it’s common sense. We can defend freedom of transaction without turning Bitcoin into a sanctuary for the worst humanity has to offer.

In my book on self-sovereignty, I wrote that with great power comes great responsibility, running a Bitcoin node is indeed powerful, and it’s up to each of us to act responsibly with that power. Today, responsibility calls for vigilance about what changes we adopt. I am communicating these thoughts as part of my ongoing effort to ensure Bitcoin remains future-proof. “Future-proofing” Bitcoin doesn’t just mean scaling it or boosting hash rate; it also means safeguarding its social acceptance and moral foundation. By voicing dissent, by switching implementations, by potentially forking if needed, we the users are stress-testing Bitcoin’s resilience in exactly the way it was designed to be: from the bottom up.

Bitcoin’s story has always been about empowerment of the individual. This current saga, the Node Wars over OP_RETURN and content, is yet another chapter in that story. I, for one, am determined to see Bitcoin thrive as a tool of financial liberation, unsullied by association with illicit content. It may ruffle feathers now, but principled stances often do. As the saying goes, “Bitcoin is for enemies”, but that doesn’t mean we have to let enemies turn it against us. My hope is that through self-sovereign action and frank dialogue, we will navigate this challenge and emerge with a Bitcoin network that is both freer and more secure, a network that can confidently serve the world for decades to come, without any shadow of disgrace on its ledger.

The choice is in front of us. By October 2025, Bitcoin Core v30 will normalise the relaying of arbitrary, potentially illicit content across the network. If we do nothing, if we keep quiet, then we silently consent to this shift. As Bitcoiners, we must ask ourselves: do we want our blockchain remembered as the foundation of sound money, or as a storage ground for abuse?

I’ve made my decision, I run Bitcoin Knots, I reject services that endorse Core v30, and I will defend a “clean” Bitcoin that remains worthy of global trust. The question is: what kind of Bitcoin are you willing to stand behind?

What if your most profitable business doesn’t have employees, customers, or an office, only discipline?

Most people see Bitcoin as an investment.

I see it as a second job, a business that runs 24/7, with zero bureaucracy and 100% ownership.

Each DCA buy is like paying yourself first, reinvesting into sovereignty, and building the foundation for generational wealth that can’t be inflated away.

1. Starting Point: Bitcoin Has No Yield

Many people look at Bitcoin through the narrow lens of traditional finance. They compare it to bonds, stocks, or real estate and conclude: “It doesn’t produce yield.”

That statement is true, but profoundly incomplete. Bitcoin doesn’t promise returns the way financial products do because it’s not designed to perform for you; it’s designed to liberate you. It doesn’t send you interest payments or quarterly dividends because it’s not a corporation or a government bond. Bitcoin is a foundation, not a faucet. It’s a free and open monetary protocol that anyone can build upon, but no one can corrupt or control.

Your yield doesn’t come from Bitcoin. It comes through Bitcoin, from what you choose to build, learn, and create around it. When you hold Bitcoin, you’re holding pure monetary energy, patiently stored and immune to manipulation. It won’t work for you automatically, but it will amplify your work if you align your life with it.

You can use it to start a business that earns in sats, to educate others, to write, to build software, or to trade your time today for sovereignty tomorrow. In that sense, Bitcoin doesn’t produce yield, it multiplies human capital.

It amplifies your discipline, your foresight, and your willingness to take responsibility for your future. It rewards those who build, not those who wait for handouts. In a world addicted to promises of passive income, Bitcoin is refreshingly honest. It offers nothing, no shortcuts, no yield, no safety nets, except the pure, incorruptible truth of math and time. And that truth becomes your foundation.

Yield, in the Bitcoin world, is not given. It’s earned through education, contribution, and conviction. And that’s exactly why I’ve started to see Bitcoin as my second job, a business I run quietly next to my main career, one that operates without employees, without customers, and without the constant noise of external dependencies. It’s the only “business” I know that doesn’t require permission, and yet demands discipline, conviction, and time.

2. Running a Business vs. Running Bitcoin

Running a traditional business is one of the hardest paths you can choose. It’s stressful, complex, and full of dependencies. You have to deal with taxes, regulations, employees, suppliers, competition, natural disaster and inflation, all while trying to stay profitable in a system that’s stacked against you.

Even if you do everything right, you remain vulnerable to forces you can’t control, central banks, policy shifts, energy costs, or changing consumer behavior. By contrast, DCA’ing into Bitcoin feels like running a business in a parallel universe, one where honesty is the protocol, time is your ally, and volatility is just the market’s way of testing conviction.

It’s a business with:

Zero employees

Zero bureaucracy

Zero counterparty risk

100% ownership

Each purchase is an act of self-sovereignty. Each stack is a reinvestment in long-term freedom. The system doesn’t require constant management, it requires consistency and trust in natural monetary law. If you treat Bitcoin like your “side business,” you start acting differently:

You allocate time to study macro trends, security, and self-custody.

You manage risk through DCA and self-discipline.

You build tools, content, or services that strengthen the ecosystem.

You connect with other Bitcoiners, creating real network value.

You’re not just stacking sats, you’re building human capital and optionality. This is your Bitcoin job: learning, building, and contributing.

On this topic, I’d like to point you to my newly published book Brick by Brick: Building a Sovereign Life on Bitcoin, now available as eBook, audiobook, hardcover, and paperback.

It’s a journey through money, health, and sovereignty, written for those who are ready to build independence one block at a time. You can get it here: Fiat Amazon (English): amzn.to/4mW2pK4 Fiat Amazon (German): amzn.to/47eLMD6 👉 BTC (English & German): twentyone.life/shop

3. Bitcoin Has No Yield - It Has Freedom

The fiat world has conditioned us to chase yield, often at the expense of our own freedom. We hand over our savings to institutions that promise returns, but in doing so, we surrender control. Our money is lent, leveraged, and inflated away while we receive a fraction of the benefit in the form of interest. We take risks we don’t fully understand, for yields that barely keep up with the erosion of purchasing power.

Bitcoin completely inverts that equation. It doesn’t offer yield, it offers optionality. The optionality to:

Leave a job you no longer enjoy.

Move your wealth across borders in minutes.

Opt out of inflation and financial surveillance or from Big Tech, Big Pharma

Say “no” when everyone else has to say “yes.”

That is freedom yield, the kind that cannot be measured in spreadsheets, interest rates, or quarterly reports. It doesn’t show up as a percentage, but it transforms the way you live, think, and act. It is the yield of autonomy, the return on taking responsibility for your own time, energy, and decisions. And that brings me to what makes Bitcoin unique as a “business.” It’s the only enterprise in which you can participate that doesn’t require permission, employees, or external dependencies.

Running a traditional business means hiring, managing, and constantly complying with rules that change faster than you can adapt. It means navigating bureaucracy, taxes, and regulation, all while fighting to stay profitable in an unstable monetary system. Running your Bitcoin business, on the other hand, means something entirely different:

Zero employees.

Zero bureaucracy.

Zero government dependency.

Zero counterparty risk.

Your “work” isn’t measured in invoices, KPIs, or profit margins, it’s measured in consistency and conviction. The market you’re serving is time, and your main product is freedom.

Every DCA buy is like performing the daily operations of this invisible business:

You’re paying yourself first.

You’re reinvesting your profits into sovereignty.

You’re building long-term infrastructure for freedom.

It might seem boring, but so is compound interest, and both require patience to reveal their magic. DCA into Bitcoin is the entrepreneur’s discipline applied to savings. It’s the quiet, repetitive work that builds strength while others chase excitement. In the end, this is what separates the fiat entrepreneur from the sovereign entrepreneur: One builds for income, the other builds for independence.

4. The Sovereign Entrepreneur

Over time, I realized I wasn’t just stacking Bitcoin, I was building on it. I was learning, creating, and contributing to a movement that values truth and resilience over speculation. Bitcoin became the anchor for my curiosity. It inspired me to study economics, energy, psychology, and technology. It taught me the value of patience and self-custody. It made me a builder again. In that sense, it became my second job, but one with no employees, no invoices, and no bureaucracy. A business that compounds knowledge and conviction instead of capital.

This is what I call the sovereign business model:

No customers to satisfy.

No suppliers to depend on.

No regulators to fear.

No environmental risk factors or dependencies.

Only you, your discipline, and the network that never sleeps. Tick-Tock next block.

5. The Real Yield

If Bitcoin produces any kind of yield, it isn’t in percentages or interest rates, it’s in principles.The rewards are intangible at first, but they’re profound and lasting.They don’t show up in your account balance; they show up in your character. If Bitcoin produces any kind of yield, it’s intangible but profound:

Knowledge yield: You begin to understand money, incentives, and human behavior.

Discipline yield: You learn to save, to wait, and to think in decades instead of days.

Freedom yield: You gain control over your time, your choices, and your future.

Mindset yield: Your thinking shifts from scarcity to abundance, from fear to clarity.

Health yield: You stop outsourcing your wellbeing to systems that profit from your weakness.

Purpose yield: As your time preference drops, your sense of purpose expands.

These forms of yield compound slowly, but they’re far more valuable than any short-term return. They build the foundation for a life that is independent, intentional, and resilient. This is the essence of TwentyOne.Life, living outside the fiat illusion, and building a sovereign life, brick by brick.

6. Closing Thought

“A traditional business builds income. Bitcoin builds independence.”

While most businesses eventually face exhaustion, competition, or regulation, Bitcoin remains open, borderless, and incorruptible. It never sleeps, never defaults, and never stops doing what it was designed to do, preserve truth across time. So yes, Bitcoin has no yield, and that’s precisely why I choose to work for it. Not to earn interest, but to earn freedom. Not to grow faster, but to grow freer.

If you treat DCA like your second job, one day it might free you from the first, and build the kind of generational wealth that isn’t measured in fiat, but in freedom.

“We can’t reform the system - we build new ones.”

1. The Day a New World Began

October 31 is a symbolic date for anyone who has looked beyond the surface of money. On this day in 2008, an unknown individual or group using the name Satoshi Nakamoto published a nine-page document titled “Bitcoin: A Peer-to-Peer Electronic Cash System.”

Those pages changed the course of history because they proposed something that no institution, bank, or government had ever achieved: a system of truth that required no trust, a network that operated on mathematics instead of manipulation. Seventeen years later, the ripple from that whitepaper has become a global wave. It has inspired millions of people to question the foundations of finance, governance, and even personal health and energy.

This year, on that same date, I release my book Brick by Brick: Building a Sovereign Life, and the timing is deliberate. The whitepaper was the spark; this book is my attempt to turn that spark into structure, a way to rebuild the systems of daily life from the ground up, guided by the same principles that made Bitcoin possible.

2. The Moment of Awakening

My journey into this world began in 2017. At the time, I was deeply involved in digital transformation projects for large organizations, helping them modernize their systems and automate their workflows. I believed technology represented progress and that efficiency automatically equaled success. Yet, despite professional achievements, I sensed something missing.

The more I optimized corporate systems, the more I saw the hidden cost: people disconnected from purpose, value diluted by inflation, data harvested for profit, and time consumed by meaningless distractions. When I discovered Bitcoin, I initially thought it was simply another technical innovation, perhaps an investment or a curiosity. But I quickly realized that it was something far deeper.

Bitcoin was not about speculation. It was about sovereignty. It rewarded patience, discipline, and proof-of-work, values that modern fiat culture had abandoned. It taught me that freedom begins where dependency ends. That insight changed everything. It shifted my focus from upgrading machines to upgrading human lives, starting with my own.

3. Why We Build

We live in a world that tells us reform is progress: vote harder, recycle more, work faster. But the uncomfortable truth is that you cannot reform a system designed to decay. A financial system built on debt will always create more debt. A consumption-based economy will always require more consumption. A culture built on lies will always fear truth.

Bitcoin rejects this logic entirely. It replaces debt with ownership, consumption with conservation, and false promises with verifiable proof. That same principle can and should guide how we live. If the financial system is broken, we build honest money. If the food system is poisoned, we grow real food. If the information system is corrupt, we host our own data. If education fails, we teach our children directly.

Brick by Brick was written as a guide for this mindset. It is not a protest, but a manual for peaceful reconstruction, a practical roadmap to create parallel systems that work precisely because they are rooted in truth and human-scale cooperation.

4. The Thinkers

Every movement begins with a shift in consciousness. Before we can build differently, we must learn to think differently. Bitcoiners, in that sense, are modern philosophers. They are people who look at what others accept as normal and begin to ask the questions that change everything.

They ask why their savings lose value every year. They wonder why governments print money while citizens tighten their belts. They question why people grow sicker and weaker despite record spending on “healthcare.” They ask why every technological advancement seems to make us less independent, not more.

These questions are the starting point of sovereignty. Once you see the pattern, you cannot unsee it. You begin to understand that much of modern life is designed not to empower you but to keep you dependent. Independent thinking is therefore the first act of rebellion, the seed of every parallel structure yet to come.

5. The Builders

Ideas alone change little until someone transforms them into reality. That is why every renaissance depends on builders, people who convert insight into structure. Builders do not wait for permission or consensus. They see what is missing and quietly create it.

Across the world, developers are writing open-source code that empowers individuals instead of corporations. Farmers are restoring soil health and feeding local communities with real food. Educators are designing self-directed learning environments that reconnect knowledge with curiosity. Engineers are decentralizing energy and communication. Families are rediscovering what intergenerational resilience means in practice.

Each of these efforts may appear small in isolation, but together they form the foundation of a new civilization, one that operates through voluntary cooperation rather than coercion. It is already taking shape, quietly and globally, and its beauty lies in its decentralization: there are no leaders to corrupt, no headquarters to capture. It grows organically wherever truth and creativity meet.

6. The Stackers

If builders create structure, stackers provide the energy that sustains it. In Bitcoin, the term “stacking sats” refers to saving small amounts of Bitcoin consistently. It is a humble act, yet deeply profound, because it transforms the way people relate to time and value.

When you start saving in sound money, you inevitably begin to think long term. You stop chasing quick wins and start planning decades ahead. You begin to see money not as a tool for consumption but as stored time, the crystallization of honest effort. Stacking sats teaches patience in a culture addicted to immediacy. It aligns your actions with reality instead of illusion.

This mindset extends far beyond finance. Every disciplined decision, whether to eat clean food, to move your body, or to focus your mind, is a kind of stacking. Each act compounds, creating reserves of health, knowledge, and freedom. Over time, these habits form the invisible architecture of sovereignty.

7. Parallel Structures, Parallel Lives

Many people say, “You can’t change the system from within,” and they are right. But that realization should not breed despair, it should inspire creativity. If the system cannot be changed, then we must build outside of it.

Around the world, people are doing exactly that. Families are forming learning communities and homeschooling their children. Individuals are rejecting processed food and returning to regenerative farming. Developers are building censorship-resistant software and privacy tools. Entrepreneurs are launching Bitcoin-native businesses that function entirely outside of the traditional banking grid.

Each of these efforts weakens dependency and strengthens resilience. Together, they demonstrate that decentralization is not chaos; it is organic order. The fiat world runs on fear. The parallel world runs on proof-of-work, on people who act rather than wait.

8. Reconnecting the Domains of Life

While writing Brick by Brick, I discovered that true sovereignty cannot be achieved in fragments. You cannot have financial freedom if your health depends on pills. You cannot enjoy privacy if your mind is trapped in distraction. You cannot build lasting independence if your attention is for sale.

Sovereignty requires integration. For that reason, the book is built around what I call the Five Pillars of Sovereignty: Money, Health, Data, Attention, and Energy.

Sound money gives stability and reduces fear of the future. Real health, grounded in nutrition, movement, and sunlight, provides the strength to live freely. Data ownership restores privacy and dignity in the digital age. Focused attention brings clarity in a world of noise. And balanced energy, both physical and emotional, fuels every other domain.

When these five pillars are aligned, they form an unshakable foundation. A life built on these principles can weather economic crises, political changes, or technological disruptions. It is antifragile by design.

9. Human Proof-of-Work

In Bitcoin mining, energy expenditure secures the network. In human life, effort and discipline secure integrity. Writing Brick by Brick was my own form of mining, a long and often demanding process that required consistency, curiosity, and faith in the long-term reward.

Through that work, I learned that sovereignty is not a product to be purchased; it is a practice that must be earned daily. Every decision, how you spend, what you eat, how you learn, what you tolerate, adds a block to the chain of your own authenticity. The more blocks you add, the more secure your personal network becomes.

10. The Birth of TwentyOne.Life

Books can plant seeds, but communities cultivate forests. That is why the next phase of my journey is TwentyOne.Life, a digital basecamp for sovereign individuals and families.

TwentyOne.Life will extend the ideas of Brick by Brick into an interactive space where readers can exchange experiences, discuss tools, and collaborate on projects. It will host conversations that bridge money, health, and technology, all through the lens of personal freedom. The vision is simple: to connect builders, thinkers, and stackers who are already living the proof-of-work philosophy, and to create a network where they can support each other in building parallel lives.

When people align around truth rather than ideology, society evolves naturally. That is what this platform aims to facilitate, coordination based on voluntary contribution and integrity.

11. Be a Builder, Support a Builder

Bitcoin Whitepaper Day is the perfect occasion to act. After two years of writing and refining, my book Brick by Brick: Building a Sovereign Life is finally available in English and German, across ebook, paperback, and hardcover formats.

You can choose whichever path fits your principles:

Fiat Amazon (English): https://amzn.to/4mW2pK4

Fiat Amazon (German): https://amzn.to/47eLMD6

BTC Payments (English & German): https://twentyone.life/shop

If you purchase with Bitcoin, you will receive a discount, a signed copy, special Bookmark and personally packaged, as a token of gratitude for supporting sovereign publishing directly.

But this call goes beyond buying a book. It is an invitation to build. Start a local initiative. Reclaim a skill. Mentor a friend. Support independent creators and educators. Each time you spend, earn, or share in alignment with your values, you are strengthening the parallel economy that will outlast the old one.

12. What Happens Next

The original Bitcoin whitepaper concluded with the modest statement: “We have proposed a system for electronic transactions without relying on trust.” From that humble beginning emerged a global network securing trillions in value and inspiring a revolution in thought.

The lesson is timeless. Small beginnings, when rooted in truth, can create unstoppable transformations. One family choosing real food can inspire a neighborhood. One entrepreneur accepting Bitcoin can trigger a local circular economy. One teacher embracing self-directed education can free dozens of young minds.

We do not need to fix the entire world at once. We simply need to lay our own brick and trust that others are doing the same.

13. The Next Civilization

Look closely and you can already see it forming: people generating energy instead of merely consuming it, developers writing open code instead of patents, artists producing truth instead of propaganda, and communities exchanging value directly with one another.

This quiet shift represents what I call the Sovereign Renaissance. It is not utopia, but something far more resilient, a society grounded in voluntary cooperation, creative independence, and technological integrity. It does not arrive with revolutions or headlines but grows steadily through our collective proof-of-work.

The fiat world continues to exist, but it is losing legitimacy. Its rules inspire compliance only among those who have stopped thinking. The builders, the thinkers, and the stackers have already moved on.

14. My Invitation to You

If you have read this far, then something within you recognizes this message. Perhaps you are already building in your own way, or perhaps you are only beginning to imagine what that could look like. Wherever you are on this path, remember that sovereignty is not a destination; it is a direction. Every honest decision, no matter how small, moves you closer to freedom and strengthens the network of others walking the same road.

I invite you to take three steps:

Read the book. It offers not just theory but practical examples of how to build sovereignty in money, health, and mindset.

Connect through TwentyOne.Life. Join a community that values truth, craftsmanship, and voluntary collaboration.

Support other builders. Each time you transact directly, share knowledge, or encourage independent work, you contribute to a system based on integrity rather than permission.

15. Closing Thoughts

The Bitcoin Whitepaper contained only nine pages, but its implications reshaped the world. It proved that durable change does not come from permission but from creation. We cannot reform systems that are fundamentally dishonest; we can only replace them with structures that are transparent, voluntary, and real.

That is what Bitcoin did for money. That is what Brick by Brick seeks to do for life. And that is what TwentyOne.Life will continue to build, patiently, deliberately, and with conviction.

Wherever you are reading this, know that you are not alone. All around the world, others are stacking, coding, growing, teaching, and creating. Together, we are building something that will last.

Be a builder. Support a builder. Stack with intention.

The next civilization is already under construction, and every brick counts.

Introduction: A New Controversy in Bitcoin’s Evolution

If you hold Bitcoin, if you call yourself a Bitcoiner, are you prepared to accept that the Bitcoin blockchain could be used to store illicit, even illegal content? This isn’t a hypothetical. Unless we act, by October 2025 the default Bitcoin Core software will make this the new reality. And if you don’t react now, your silence means acceptance.

Bitcoin is facing a pivotal controversy that cuts to the heart of its identity. The debate centres on a proposed change in Bitcoin’s core software that would remove longstanding limits on storing arbitrary data in transactions. On the surface, this change sounds technical – raising the OP_RETURN data limit from 80 bytes to nearly 4 megabytes, but its implications are profoundly human. Supporters hail it as an overdue embrace of censorship-resistance, while critics warn it could turn the blockchain into a host for illegal or abusive content. As a Bitcoiner who champions self-sovereignty and Bitcoin’s reputation as sound money, I find myself firmly in the latter camp. This article, written from my personal perspective and drawing on my book’s focus (Brick by Brick - <https://twentyone.life/brick-by-brick>) on self-sovereignty, explores why I’m taking a stand by running alternative software and even boycotting certain services, all in the name of a “clean” future for Bitcoin.

Background: Bitcoin Core v30 and the OP_RETURN Debate

At issue is a change slated for the upcoming Bitcoin Core version 30 (expected October 2025). Bitcoin Core is the dominant software for running nodes (over 75% of nodes run so its defaults largely define network behaviour. The core developers have decided to unshackle the OP_RETURN field, which historically allowed embedding only a tiny piece of data (≤83 bytes) in a transaction. This limit acted as a de facto “spam filter”, discouraging users from turning Bitcoin’s ledger into a generic data storage system.

Under Core v30, that filter is being removed entirely: users will be able to attach much larger data payloads, up to the size of a full block (~4MB), in a single transaction output. Moreover, Bitcoin Core will eliminate the configuration options (data carrier settings) that previously let node operators refuse relaying big OP_RETURN transactions. In short, the new default policy is “anything goes” for data, and individual node runners won’t easily opt out. While v30 still offers command-line tweaks to impose custom limits, those are now deprecated warnings likely to be removed later.

Why make this change? Proponents argue it’s a pragmatic response to reality. The 80-byte cap, they say, has been routinely bypassed by creative users who already insert larger data through other means – for example, using Taproot witness data or fake outputs (as seen in the 2023 Ordinals/“inscriptions” craze that let people embed images and art on Bitcoin). These workarounds are actually worse for the network: since the data is hidden in spendable outputs or witness scripts, it can bloat the UTXO set (the list of unspent coins) and increase validation costs for all nodes. By contrast, OP_RETURN outputs are provably unspendable and easily prunable. In the eyes of Core developers, it’s better to let people put data in OP_RETURN (where it doesn’t harm UTXO or decentralisation) than to have them continue abusing more harmful trick. Removing the cap “yields at least two tangible benefits: a cleaner UTXO set and more consistent default behaviour,” explained developer Greg Sanders. The change also aligns with Bitcoin’s values of neutrality, if a transaction is valid and pays the fee, who are nodes to censor it? Core maintainers like Gloria Zhao argue that trying to filter transactions at the node level is futile and against the principle of censorship-resistance.

On the other side, critics are alarmed. They counter that dropping these limits will open the floodgates to arbitrary data, fundamentally altering Bitcoin’s purpose. The blockchain could become a bloated “immutable database” of random content, potentially crowding out financial transactions with higher fees and diluting Bitcoin’s use as peer-to-peer money. What’s more, unbounded data storage invites spam, people could stuff blocks with endless memes, ads, or junk simply because they’re willing to pay. It’s a replay of the Blocksize War arguments, but instead of bigger blocks for payments, it’s bigger payloads for non-monetary data. The community is starkly divided: should Bitcoin evolve to support broader use cases (data, NFTs, digital artifacts), or should it resist becoming a free-for-all content repository and stick to financial utility? These positions are diametrically opposed, and the conflict has been heated – drawing comparisons to the acrimony of the 2017 blocksize debates.

Notably, longtime Bitcoin developer Luke Dashjr (author of an alternative client called Bitcoin Knots - https://x.com/LukeDashjr) has been one of the most vocal opponents besides Bitcoin Mechanic and Bitcoin University ( primal.net/kratter). He warns that the removal of what he bluntly calls “spam filters” is potentially harmful to the network and its users. Dashjr has publicly urged node operators to avoid upgrading to Core v30 or to switch to alternative software like Bitcoin Knots. In fact, many Bitcoiners have already acted on that advice. When the OP_RETURN plan was announced and fast-tracked earlier this year, there was a surge of users migrating their nodes from Core to Knots, by some estimates, over 15% of previously Core nodes switched to Bitcoin Knots in protest. The stage is set for a grass-roots pushback using Bitcoin’s own strength: decentralisation. True to the mantra of self-sovereignty, if you disagree with the default rules, you are free to run a node that reflects your values. I count myself among those taking that step.

Illicit Content on the Blockchain: The Serious Risks

Why am I, and others, so concerned about lifting the data limits? Because it’s not just “cute cat pictures” or art collections that could find their way onto Bitcoin’s ledger. The most dire possibility is the inclusion of illicit and abusive content in an immutable, globally replicated chain. This isn’t idle paranoia; it’s a genuine risk recognised by both sides of the debate. Even the advocates of OP_RETURN freedom acknowledge the “undesirable second-order effects” that could follow. Let’s spell it out: What if someone starts embedding child sexual abuse material (CSAM) or other illegal data in Bitcoin transactions? Once mined into a block, that content is there forever, every full node would unknowingly host it on their hard drive as part of the blockchain spreaded on tens of thousands nodes across the world. This scenario is a nightmare for obvious moral reasons, and it also poses a legal and reputational threat to anyone running a node or the Bitcoin network as a whole. Besides this, to spin up a new node will take longer and need higher technical hardware which leads to centralisation.

Unfortunately, the threat is not theoretical. It has already happened on a small scale. Researchers have found that forbidden content made its way onto Bitcoin as early as 2013, albeit in an obscure form. In 2018, a paper famously claimed that Bitcoin’s blockchain contained links to child pornography; at the time, critics dismissed it as sensationalism since only a few bytes of encoded data were involved and Core’s filters limited further abuse. But today we’re looking at a very different landscape. The data per block is increasing dramatically with the new policy. A concerned Bitcoiner known as “Bitcoin Mechanic” ( primal.net/p/nprofile1qqs8fl79rnpsz5x00xmvkvtd8g2u7ve2k2dr3lkfadyy4v24r4k3s4sh8dmel) recently warned that removing the filter “will draw unforeseen consequences,” meaning content like child pornography can appear on the Bitcoin blockchain” once v30 goes live. His point is straightforward: if you give bad actors the ability to inject large payloads, someone will inevitably push the worst kind of content into the system. And perversely, there’s a twisted incentive for them to do so: “Getting other people to store it for you is vastly preferable to storing it yourself,” Mechanic notes, what better way for criminals to disseminate vile material than piggyback on tens of thousands of innocent Bitcoin nodes?

Core developers have responded that these fears may be overblown. They often cite examples of other blockchains (for instance, Monero or Ethereum) that don’t have such data limits yet haven’t become overrun with illegal content. They stress that Bitcoin’s permissionless nature means anything could be written to it, but that doesn’t mean an epidemic of criminal data is imminent. Perhaps, but I would counter that Bitcoin’s global prominence and immutable design make it a uniquely attractive target for someone trying to cause chaos or discredit the system. It only takes one high-profile incident of truly heinous content on Bitcoin to unleash a regulatory crackdown. Remember, Bitcoin’s censorship-resistance cuts both ways: it empowers individuals, but it also neutralises traditional controls, which is exactly why governments get antsy when crimes enter the mix.

The legal implications of this are untested and scary. If a Bitcoin block contains illegal pornography or violent propaganda, could authorities argue that every node operator is technically in possession of contraband data? Some in the community worry that, yes, this could give governments a “perfect excuse to outlaw Bitcoin or make running a node illegal”. Even if that outcome is unlikely in jurisdictions that understand how Bitcoin works, the mere perception that Bitcoin is hosting criminal content would be a PR disaster. It would hand ammunition to anti-crypto politicians and could make regulators slam the brakes on adoption. As a Bitcoiner who wants to see this technology thrive, I find that risk unacceptable. Bitcoin’s social contract might be robust against internal dissent, but it’s not immune to external legal attack. Preserving Bitcoin’s integrity means ensuring it doesn’t become synonymous with “dark web file storage” in the public eye.

Embracing Self-Sovereignty: Why I Run Bitcoin Knots

My response to this situation has been guided by one of Bitcoin’s core principles: self-sovereignty. In essence, self-sovereignty means taking full ownership of your participation in the network, holding your own keys, and running your own node with the rules you choose. In the book I authored on Bitcoin and self-sovereign principles, I emphasised that running a node is more than a technical task; it’s an expression of personal agency and values. Now, faced with Bitcoin Core’s direction that I deeply disagree with, I’m putting that ethos into practice.

For the past four months, I have been running Bitcoin Knots instead of the standard Bitcoin Core software. Bitcoin Knots is a well-established alternative client (maintained by Luke Dashjr) that, in many ways, is identical to Core except for a few important differences, notably, Knots retains stricter limits on OP_RETURN data and gives the user full control over relay filters. In fact, Knots by default still caps OP_RETURN at 40 bytes (the old limit from years ago) and allows only one OP_RETURN output per transaction. It’s basically “Bitcoin Core, but with the spam filter intact.” By running Knots, my node will not relay or mine the kind of oversized data-storing transactions that Core v30 endorses. More importantly, it signals my support for a vision of Bitcoin that prioritises financial transactions over arbitrary data. Knots users (myself included) see ourselves as defending Bitcoin’s integrity from a controversial experiment. We are effectively saying, “Not on my node!” when it comes to turning Bitcoin into an uncensored data dump.

I’m far from alone in this choice. As mentioned, a substantial minority of node operators are switching to Knots or sticking with older Core versions. This grass roots movement is reminiscent of how users can enforce their preferences in Bitcoin – much like the User Activated Soft Fork (UASF) concept, node runners can ‘vote’ by choosing which software to run. If enough of us reject Core v30, it could create economic incentives for miners to think twice about stuffing blocks with junk that a portion of the network won’t relay or perhaps even accept. (To be clear, Knots today does accept blocks created under Core’s new rules – it’s not a hard fork. The divergence is in relay policy and default behaviour, not consensus rules. This is a fight being waged via network policy, not chain splits… at least not yet.)

Self-sovereignty also means accepting personal responsibility for what I support in the network. That extends beyond just the software I run. It also influences my choices as a customer and community member. In light of the OP_RETURN controversy, I have decided on a few concrete actions, which I’ll outline here:

Running a “clean” node: I’ve migrated all my nodes to Bitcoin Knots and will continue to do so for the foreseeable future. This ensures that I am not propagating or validating illicit data beyond the absolute minimum required by consensus. If a bloated transaction or block crosses my node, Knots’ policies will treat it with the maximum strictness allowed (dropping it from mempool if possible, and certainly not relaying such transactions to peers). This is my way of keeping my corner of the Bitcoin network as clean of illicit content as possible. It’s a personal stand: I do not want even the chance of illegal material passing through my machine.

Boycotting services that endorse Core v30: I am discontinuing my use of any exchanges, custodians, or Bitcoin companies that I know are upgrading to or support the Core v30 software without protest. For example, if a company like River Financial or a tech firm like Blockstream chooses to run Core v30 nodes (thus knowingly accepting the relay of unlimited content, illicit or otherwise), then I will not be doing business with them. Those organizations might trust their lawyers or regulators to sort out the fallout of hosting illicit data on their nodes – that’s their prerogative. But I cannot in good conscience support institutions that, in my view, are inviting a flood of abusive content onto the Bitcoin blockchain and risking its reputation. My money and support will go to those who keep Bitcoin robust and respectable.

Advocating for a “clean” Bitcoin (even if it means a fork): Looking ahead, I suspect that other major players in the Bitcoin ecosystem share my concern, even if they aren’t voicing it loudly yet. Think of large public companies holding Bitcoin in their treasuries, or firms planning Bitcoin ETFs. The last thing these institutions want is to be entangled with a network that could inadvertently facilitate the spread of illegal content. It’s not hard to imagine some of them drawing a line: if Bitcoin’s protocol won’t address this problem, they might resort to extraordinary measures. This could include supporting a hard fork to create a “clean” version of Bitcoin that excises or filters out illicit material. BlackRock, for instance, is on the cusp of launching a spot Bitcoin ETF. In BlackRock’s own filings, they note that in the event of a fork, they have full discretion to decide which chain to consider the “real” Bitcoin for their fund.That means if a new fork gained momentum – say, a Bitcoin variant with strict protocol rules against arbitrary data – BlackRock could opt to adopt it for their ETF (or conversely, to abandon a chain that becomes too toxic). While this scenario sounds extreme, it’s entirely within the realm of possibility. The very fact that we’re discussing child pornography on the blockchain may prompt powerful stakeholders to assert control to protect their investments. I’m not actively calling for an immediate fork, that’s a complex, last-resort path, but I do believe that if Bitcoin Core’s path leads to legal quagmires, the market will find a way to course-correct, even if it means a chain split. My hope is that by raising awareness now, we can avert such drastic outcomes. But make no mistake: Bitcoin’s future must not include being a playground for criminal content, and I’ll support any serious effort to ensure that.

Bitcoin’s Future: Balancing Freedom and Responsibility

The controversy over OP_RETURN and illicit content forces an uncomfortable but necessary conversation about the future we want for Bitcoin. On one side is the ideal of total neutrality, Bitcoin as an unfilterable, permissionless ledger where “code is law” and even questionable data is just data. On the other side is the recognition that Bitcoin does not exist in a vacuum: if we undermine its primary use case as money or subject its participants to legal peril, we could kill the proverbial goose that lays the golden eggs. Finding the right balance is tricky. We cherish Bitcoin’s censorship-resistance precisely because it protects financial freedom and speech. Yet, does rejecting any filtering, even of grotesquely abusive content, truly serve the cause of freedom? Or does it hand enemies of Bitcoin the very weapon they need to attack it? These are challenging questions, and reasonable people in the community answer them differently.

For me, the answer comes back to self-sovereignty and consent. I did not sign up to store illicit images or arbitrary gigabytes of data on my node, that’s not the social contract under which I joined Bitcoin. My consent as a node operator matters. True decentralisation means we, the users get to collectively decide what the blockchain is for, by either running or not running certain code. It’s heartening to see that even Core developers acknowledge this in principle: “If Bitcoin Core’s contributors ever abandon [Bitcoin’s core] values… the community will switch to another node implementation that does it better,” wrote Gloria Zhao amidst the debate. I’d argue that forcing nodes to relay and store unlimited junk (with potentially ghastly contents) is a departure from the values that brought many of us to Bitcoin. And indeed, we’re seeing the community vote with its feet, or rather with its node software.

Moving forward, I believe Bitcoin will be stress-tested on this front. The coming months and years will reveal whether the network can accommodate new use-cases (like data inscriptions) without losing its soul – or whether a correction is needed. Perhaps Bitcoin Core’s gambit will pay off: maybe the “spam” will remain manageable, new pruning techniques will mitigate the bloat, and no criminal will attempt to abuse the blockchain’s openness. In that best case, my concerns would be eased (and I’d gladly acknowledge an overabundance of caution on my part). But if the worst case materialises, if obscene data starts showing up in blocks, if typical users find the chain clogged with non-financial data, if governments use this as a cudgel – then the community must be ready to respond decisively. Hard forks have happened before in Bitcoin’s history when values were at stake (recall the split that created Bitcoin Cash in 2017 over a blocksize dispute). A fork to preserve Bitcoin’s legal cleanliness and focused mission might become not just acceptable but essential to “future-proof” the network. And unlike a protocol tweak coming from a small group, a community or institution-driven fork would reflect a broad consensus that Bitcoin as it was is worth defending. BlackRock and other institutional players entering the space could ironically become allies in keeping Bitcoin safe for mainstream use – they will not tolerate holding an asset tainted by crime, so they have every incentive to back a solution, even if it’s a controversial one.

Conclusion: Upholding Bitcoin’s Integrity

In closing, my stance can be distilled to this: Bitcoin’s strength lies in our ability to choose and enforce the rules that best uphold the network’s purpose and integrity. As a self-sovereign participant, I choose to reject the notion that Bitcoin must accept everything in the name of “freedom,” especially when that freedom can be cynically exploited to Bitcoin’s detriment. Instead, I align with the principle that some judicious constraints, whether at the software policy level or the community social level, are necessary to keep Bitcoin healthy, useful, and legally accessible to all. This is a nuanced position, and it may be polarising. Some will accuse me of advocating “censorship” or betraying Bitcoin’s neutrality. I respect the purist viewpoint, but I humbly disagree in this case. Refusing to store illegal content is not tyranny; it’s common sense. We can defend freedom of transaction without turning Bitcoin into a sanctuary for the worst humanity has to offer.

In my book on self-sovereignty, I wrote that with great power comes great responsibility, running a Bitcoin node is indeed powerful, and it’s up to each of us to act responsibly with that power. Today, responsibility calls for vigilance about what changes we adopt. I am communicating these thoughts as part of my ongoing effort to ensure Bitcoin remains future-proof. “Future-proofing” Bitcoin doesn’t just mean scaling it or boosting hash rate; it also means safeguarding its social acceptance and moral foundation. By voicing dissent, by switching implementations, by potentially forking if needed, we the users are stress-testing Bitcoin’s resilience in exactly the way it was designed to be: from the bottom up.

Bitcoin’s story has always been about empowerment of the individual. This current saga, the Node Wars over OP_RETURN and content, is yet another chapter in that story. I, for one, am determined to see Bitcoin thrive as a tool of financial liberation, unsullied by association with illicit content. It may ruffle feathers now, but principled stances often do. As the saying goes, “Bitcoin is for enemies”, but that doesn’t mean we have to let enemies turn it against us. My hope is that through self-sovereign action and frank dialogue, we will navigate this challenge and emerge with a Bitcoin network that is both freer and more secure, a network that can confidently serve the world for decades to come, without any shadow of disgrace on its ledger.

The choice is in front of us. By October 2025, Bitcoin Core v30 will normalise the relaying of arbitrary, potentially illicit content across the network. If we do nothing, if we keep quiet, then we silently consent to this shift. As Bitcoiners, we must ask ourselves: do we want our blockchain remembered as the foundation of sound money, or as a storage ground for abuse?

I’ve made my decision, I run Bitcoin Knots, I reject services that endorse Core v30, and I will defend a “clean” Bitcoin that remains worthy of global trust. The question is: what kind of Bitcoin are you willing to stand behind?

Correct, Bitcoin’s consensus is global and enforced by all validating nodes, not by local policies or one developer’s code. Node filters like in Knots don’t change consensus rules; they only affect what transactions a node relays or mines.

These local policies let operators manage bandwidth or mempool use, but the shared consensus remains untouched, that’s what keeps Bitcoin decentralized and resilient.

It’s not about promoting Luke’s version as the only way, but about understanding what the different configurations actually do and how they affect transaction propagation, policy, and mempool behavior.

“The best” setup really depends on your goals, whether you want to optimize for policy experimentation, stricter relay rules, or simply stay aligned with Bitcoin Core defaults. Knots is essentially Bitcoin Core with additional transparency and policy options exposed. You can use those settings directly on your own Core node if you prefer; Knots just makes them more accessible.

No one solution “solves” spam, it’s an ongoing tradeoff between openness and efficiency. But core v30 and opeing OPRETTURN does not help and opens the gate to even more spam.
The goal is to keep exploring tools and configurations that let node operators choose their own validation and relay policies.

That’s exactly the point of running your own node, you decide your relay and validation policies, and I decide mine. If my node doesn’t relay your BIP47 or tx0 transactions, it’s because I’ve chosen tighter policies to reduce unnecessary data and long-term storage risk. You can route around it, that’s how Bitcoin’s peer network is designed to work.

Knots isn’t “propaganda.” It’s Bitcoin Core with additional configurability and better defaults for people who take node sovereignty seriously. Both Core and Knots enforce the same consensus rules, neither breaks Bitcoin, and both coexist perfectly fine on the network.

If you prefer to relay every kind of transaction, go ahead. Others choose to run leaner, more conservative nodes to avoid bloat and potential legal or operational risks. That’s not brainwashing, that’s responsible node operation and informed choice.

Introduction: A New Controversy in Bitcoin’s Evolution

If you hold Bitcoin, if you call yourself a Bitcoiner, are you prepared to accept that the Bitcoin blockchain could be used to store illicit, even illegal content? This isn’t a hypothetical. Unless we act, by October 2025 the default Bitcoin Core software will make this the new reality. And if you don’t react now, your silence means acceptance.

Bitcoin is facing a pivotal controversy that cuts to the heart of its identity. The debate centres on a proposed change in Bitcoin’s core software that would remove longstanding limits on storing arbitrary data in transactions. On the surface, this change sounds technical – raising the OP_RETURN data limit from 80 bytes to nearly 4 megabytes, but its implications are profoundly human. Supporters hail it as an overdue embrace of censorship-resistance, while critics warn it could turn the blockchain into a host for illegal or abusive content. As a Bitcoiner who champions self-sovereignty and Bitcoin’s reputation as sound money, I find myself firmly in the latter camp. This article, written from my personal perspective and drawing on my book’s focus (Brick by Brick - <https://twentyone.life/brick-by-brick>) on self-sovereignty, explores why I’m taking a stand by running alternative software and even boycotting certain services, all in the name of a “clean” future for Bitcoin.

Background: Bitcoin Core v30 and the OP_RETURN Debate

At issue is a change slated for the upcoming Bitcoin Core version 30 (expected October 2025). Bitcoin Core is the dominant software for running nodes (over 75% of nodes run so its defaults largely define network behaviour. The core developers have decided to unshackle the OP_RETURN field, which historically allowed embedding only a tiny piece of data (≤83 bytes) in a transaction. This limit acted as a de facto “spam filter”, discouraging users from turning Bitcoin’s ledger into a generic data storage system.

Under Core v30, that filter is being removed entirely: users will be able to attach much larger data payloads, up to the size of a full block (~4MB), in a single transaction output. Moreover, Bitcoin Core will eliminate the configuration options (data carrier settings) that previously let node operators refuse relaying big OP_RETURN transactions. In short, the new default policy is “anything goes” for data, and individual node runners won’t easily opt out. While v30 still offers command-line tweaks to impose custom limits, those are now deprecated warnings likely to be removed later.

Why make this change? Proponents argue it’s a pragmatic response to reality. The 80-byte cap, they say, has been routinely bypassed by creative users who already insert larger data through other means – for example, using Taproot witness data or fake outputs (as seen in the 2023 Ordinals/“inscriptions” craze that let people embed images and art on Bitcoin). These workarounds are actually worse for the network: since the data is hidden in spendable outputs or witness scripts, it can bloat the UTXO set (the list of unspent coins) and increase validation costs for all nodes. By contrast, OP_RETURN outputs are provably unspendable and easily prunable. In the eyes of Core developers, it’s better to let people put data in OP_RETURN (where it doesn’t harm UTXO or decentralisation) than to have them continue abusing more harmful trick. Removing the cap “yields at least two tangible benefits: a cleaner UTXO set and more consistent default behaviour,” explained developer Greg Sanders. The change also aligns with Bitcoin’s values of neutrality, if a transaction is valid and pays the fee, who are nodes to censor it? Core maintainers like Gloria Zhao argue that trying to filter transactions at the node level is futile and against the principle of censorship-resistance.

On the other side, critics are alarmed. They counter that dropping these limits will open the floodgates to arbitrary data, fundamentally altering Bitcoin’s purpose. The blockchain could become a bloated “immutable database” of random content, potentially crowding out financial transactions with higher fees and diluting Bitcoin’s use as peer-to-peer money. What’s more, unbounded data storage invites spam, people could stuff blocks with endless memes, ads, or junk simply because they’re willing to pay. It’s a replay of the Blocksize War arguments, but instead of bigger blocks for payments, it’s bigger payloads for non-monetary data. The community is starkly divided: should Bitcoin evolve to support broader use cases (data, NFTs, digital artifacts), or should it resist becoming a free-for-all content repository and stick to financial utility? These positions are diametrically opposed, and the conflict has been heated – drawing comparisons to the acrimony of the 2017 blocksize debates.

Notably, longtime Bitcoin developer Luke Dashjr (author of an alternative client called Bitcoin Knots - https://x.com/LukeDashjr) has been one of the most vocal opponents besides Bitcoin Mechanic and Bitcoin University ( primal.net/kratter). He warns that the removal of what he bluntly calls “spam filters” is potentially harmful to the network and its users. Dashjr has publicly urged node operators to avoid upgrading to Core v30 or to switch to alternative software like Bitcoin Knots. In fact, many Bitcoiners have already acted on that advice. When the OP_RETURN plan was announced and fast-tracked earlier this year, there was a surge of users migrating their nodes from Core to Knots, by some estimates, over 15% of previously Core nodes switched to Bitcoin Knots in protest. The stage is set for a grass-roots pushback using Bitcoin’s own strength: decentralisation. True to the mantra of self-sovereignty, if you disagree with the default rules, you are free to run a node that reflects your values. I count myself among those taking that step.

Illicit Content on the Blockchain: The Serious Risks

Why am I, and others, so concerned about lifting the data limits? Because it’s not just “cute cat pictures” or art collections that could find their way onto Bitcoin’s ledger. The most dire possibility is the inclusion of illicit and abusive content in an immutable, globally replicated chain. This isn’t idle paranoia; it’s a genuine risk recognised by both sides of the debate. Even the advocates of OP_RETURN freedom acknowledge the “undesirable second-order effects” that could follow. Let’s spell it out: What if someone starts embedding child sexual abuse material (CSAM) or other illegal data in Bitcoin transactions? Once mined into a block, that content is there forever, every full node would unknowingly host it on their hard drive as part of the blockchain spreaded on tens of thousands nodes across the world. This scenario is a nightmare for obvious moral reasons, and it also poses a legal and reputational threat to anyone running a node or the Bitcoin network as a whole. Besides this, to spin up a new node will take longer and need higher technical hardware which leads to centralisation.

Unfortunately, the threat is not theoretical. It has already happened on a small scale. Researchers have found that forbidden content made its way onto Bitcoin as early as 2013, albeit in an obscure form. In 2018, a paper famously claimed that Bitcoin’s blockchain contained links to child pornography; at the time, critics dismissed it as sensationalism since only a few bytes of encoded data were involved and Core’s filters limited further abuse. But today we’re looking at a very different landscape. The data per block is increasing dramatically with the new policy. A concerned Bitcoiner known as “Bitcoin Mechanic” ( primal.net/p/nprofile1qqs8fl79rnpsz5x00xmvkvtd8g2u7ve2k2dr3lkfadyy4v24r4k3s4sh8dmel) recently warned that removing the filter “will draw unforeseen consequences,” meaning content like child pornography can appear on the Bitcoin blockchain” once v30 goes live. His point is straightforward: if you give bad actors the ability to inject large payloads, someone will inevitably push the worst kind of content into the system. And perversely, there’s a twisted incentive for them to do so: “Getting other people to store it for you is vastly preferable to storing it yourself,” Mechanic notes, what better way for criminals to disseminate vile material than piggyback on tens of thousands of innocent Bitcoin nodes?

Core developers have responded that these fears may be overblown. They often cite examples of other blockchains (for instance, Monero or Ethereum) that don’t have such data limits yet haven’t become overrun with illegal content. They stress that Bitcoin’s permissionless nature means anything could be written to it, but that doesn’t mean an epidemic of criminal data is imminent. Perhaps, but I would counter that Bitcoin’s global prominence and immutable design make it a uniquely attractive target for someone trying to cause chaos or discredit the system. It only takes one high-profile incident of truly heinous content on Bitcoin to unleash a regulatory crackdown. Remember, Bitcoin’s censorship-resistance cuts both ways: it empowers individuals, but it also neutralises traditional controls, which is exactly why governments get antsy when crimes enter the mix.

The legal implications of this are untested and scary. If a Bitcoin block contains illegal pornography or violent propaganda, could authorities argue that every node operator is technically in possession of contraband data? Some in the community worry that, yes, this could give governments a “perfect excuse to outlaw Bitcoin or make running a node illegal”. Even if that outcome is unlikely in jurisdictions that understand how Bitcoin works, the mere perception that Bitcoin is hosting criminal content would be a PR disaster. It would hand ammunition to anti-crypto politicians and could make regulators slam the brakes on adoption. As a Bitcoiner who wants to see this technology thrive, I find that risk unacceptable. Bitcoin’s social contract might be robust against internal dissent, but it’s not immune to external legal attack. Preserving Bitcoin’s integrity means ensuring it doesn’t become synonymous with “dark web file storage” in the public eye.

Embracing Self-Sovereignty: Why I Run Bitcoin Knots

My response to this situation has been guided by one of Bitcoin’s core principles: self-sovereignty. In essence, self-sovereignty means taking full ownership of your participation in the network, holding your own keys, and running your own node with the rules you choose. In the book I authored on Bitcoin and self-sovereign principles, I emphasised that running a node is more than a technical task; it’s an expression of personal agency and values. Now, faced with Bitcoin Core’s direction that I deeply disagree with, I’m putting that ethos into practice.

For the past four months, I have been running Bitcoin Knots instead of the standard Bitcoin Core software. Bitcoin Knots is a well-established alternative client (maintained by Luke Dashjr) that, in many ways, is identical to Core except for a few important differences, notably, Knots retains stricter limits on OP_RETURN data and gives the user full control over relay filters. In fact, Knots by default still caps OP_RETURN at 40 bytes (the old limit from years ago) and allows only one OP_RETURN output per transaction. It’s basically “Bitcoin Core, but with the spam filter intact.” By running Knots, my node will not relay or mine the kind of oversized data-storing transactions that Core v30 endorses. More importantly, it signals my support for a vision of Bitcoin that prioritises financial transactions over arbitrary data. Knots users (myself included) see ourselves as defending Bitcoin’s integrity from a controversial experiment. We are effectively saying, “Not on my node!” when it comes to turning Bitcoin into an uncensored data dump.

I’m far from alone in this choice. As mentioned, a substantial minority of node operators are switching to Knots or sticking with older Core versions. This grass roots movement is reminiscent of how users can enforce their preferences in Bitcoin – much like the User Activated Soft Fork (UASF) concept, node runners can ‘vote’ by choosing which software to run. If enough of us reject Core v30, it could create economic incentives for miners to think twice about stuffing blocks with junk that a portion of the network won’t relay or perhaps even accept. (To be clear, Knots today does accept blocks created under Core’s new rules – it’s not a hard fork. The divergence is in relay policy and default behaviour, not consensus rules. This is a fight being waged via network policy, not chain splits… at least not yet.)

Self-sovereignty also means accepting personal responsibility for what I support in the network. That extends beyond just the software I run. It also influences my choices as a customer and community member. In light of the OP_RETURN controversy, I have decided on a few concrete actions, which I’ll outline here:

Running a “clean” node: I’ve migrated all my nodes to Bitcoin Knots and will continue to do so for the foreseeable future. This ensures that I am not propagating or validating illicit data beyond the absolute minimum required by consensus. If a bloated transaction or block crosses my node, Knots’ policies will treat it with the maximum strictness allowed (dropping it from mempool if possible, and certainly not relaying such transactions to peers). This is my way of keeping my corner of the Bitcoin network as clean of illicit content as possible. It’s a personal stand: I do not want even the chance of illegal material passing through my machine.

Boycotting services that endorse Core v30: I am discontinuing my use of any exchanges, custodians, or Bitcoin companies that I know are upgrading to or support the Core v30 software without protest. For example, if a company like River Financial or a tech firm like Blockstream chooses to run Core v30 nodes (thus knowingly accepting the relay of unlimited content, illicit or otherwise), then I will not be doing business with them. Those organizations might trust their lawyers or regulators to sort out the fallout of hosting illicit data on their nodes – that’s their prerogative. But I cannot in good conscience support institutions that, in my view, are inviting a flood of abusive content onto the Bitcoin blockchain and risking its reputation. My money and support will go to those who keep Bitcoin robust and respectable.

Advocating for a “clean” Bitcoin (even if it means a fork): Looking ahead, I suspect that other major players in the Bitcoin ecosystem share my concern, even if they aren’t voicing it loudly yet. Think of large public companies holding Bitcoin in their treasuries, or firms planning Bitcoin ETFs. The last thing these institutions want is to be entangled with a network that could inadvertently facilitate the spread of illegal content. It’s not hard to imagine some of them drawing a line: if Bitcoin’s protocol won’t address this problem, they might resort to extraordinary measures. This could include supporting a hard fork to create a “clean” version of Bitcoin that excises or filters out illicit material. BlackRock, for instance, is on the cusp of launching a spot Bitcoin ETF. In BlackRock’s own filings, they note that in the event of a fork, they have full discretion to decide which chain to consider the “real” Bitcoin for their fund.That means if a new fork gained momentum – say, a Bitcoin variant with strict protocol rules against arbitrary data – BlackRock could opt to adopt it for their ETF (or conversely, to abandon a chain that becomes too toxic). While this scenario sounds extreme, it’s entirely within the realm of possibility. The very fact that we’re discussing child pornography on the blockchain may prompt powerful stakeholders to assert control to protect their investments. I’m not actively calling for an immediate fork, that’s a complex, last-resort path, but I do believe that if Bitcoin Core’s path leads to legal quagmires, the market will find a way to course-correct, even if it means a chain split. My hope is that by raising awareness now, we can avert such drastic outcomes. But make no mistake: Bitcoin’s future must not include being a playground for criminal content, and I’ll support any serious effort to ensure that.

Bitcoin’s Future: Balancing Freedom and Responsibility

The controversy over OP_RETURN and illicit content forces an uncomfortable but necessary conversation about the future we want for Bitcoin. On one side is the ideal of total neutrality, Bitcoin as an unfilterable, permissionless ledger where “code is law” and even questionable data is just data. On the other side is the recognition that Bitcoin does not exist in a vacuum: if we undermine its primary use case as money or subject its participants to legal peril, we could kill the proverbial goose that lays the golden eggs. Finding the right balance is tricky. We cherish Bitcoin’s censorship-resistance precisely because it protects financial freedom and speech. Yet, does rejecting any filtering, even of grotesquely abusive content, truly serve the cause of freedom? Or does it hand enemies of Bitcoin the very weapon they need to attack it? These are challenging questions, and reasonable people in the community answer them differently.

For me, the answer comes back to self-sovereignty and consent. I did not sign up to store illicit images or arbitrary gigabytes of data on my node, that’s not the social contract under which I joined Bitcoin. My consent as a node operator matters. True decentralisation means we, the users get to collectively decide what the blockchain is for, by either running or not running certain code. It’s heartening to see that even Core developers acknowledge this in principle: “If Bitcoin Core’s contributors ever abandon [Bitcoin’s core] values… the community will switch to another node implementation that does it better,” wrote Gloria Zhao amidst the debate. I’d argue that forcing nodes to relay and store unlimited junk (with potentially ghastly contents) is a departure from the values that brought many of us to Bitcoin. And indeed, we’re seeing the community vote with its feet, or rather with its node software.

Moving forward, I believe Bitcoin will be stress-tested on this front. The coming months and years will reveal whether the network can accommodate new use-cases (like data inscriptions) without losing its soul – or whether a correction is needed. Perhaps Bitcoin Core’s gambit will pay off: maybe the “spam” will remain manageable, new pruning techniques will mitigate the bloat, and no criminal will attempt to abuse the blockchain’s openness. In that best case, my concerns would be eased (and I’d gladly acknowledge an overabundance of caution on my part). But if the worst case materialises, if obscene data starts showing up in blocks, if typical users find the chain clogged with non-financial data, if governments use this as a cudgel – then the community must be ready to respond decisively. Hard forks have happened before in Bitcoin’s history when values were at stake (recall the split that created Bitcoin Cash in 2017 over a blocksize dispute). A fork to preserve Bitcoin’s legal cleanliness and focused mission might become not just acceptable but essential to “future-proof” the network. And unlike a protocol tweak coming from a small group, a community or institution-driven fork would reflect a broad consensus that Bitcoin as it was is worth defending. BlackRock and other institutional players entering the space could ironically become allies in keeping Bitcoin safe for mainstream use – they will not tolerate holding an asset tainted by crime, so they have every incentive to back a solution, even if it’s a controversial one.

Conclusion: Upholding Bitcoin’s Integrity

In closing, my stance can be distilled to this: Bitcoin’s strength lies in our ability to choose and enforce the rules that best uphold the network’s purpose and integrity. As a self-sovereign participant, I choose to reject the notion that Bitcoin must accept everything in the name of “freedom,” especially when that freedom can be cynically exploited to Bitcoin’s detriment. Instead, I align with the principle that some judicious constraints, whether at the software policy level or the community social level, are necessary to keep Bitcoin healthy, useful, and legally accessible to all. This is a nuanced position, and it may be polarising. Some will accuse me of advocating “censorship” or betraying Bitcoin’s neutrality. I respect the purist viewpoint, but I humbly disagree in this case. Refusing to store illegal content is not tyranny; it’s common sense. We can defend freedom of transaction without turning Bitcoin into a sanctuary for the worst humanity has to offer.

In my book on self-sovereignty, I wrote that with great power comes great responsibility, running a Bitcoin node is indeed powerful, and it’s up to each of us to act responsibly with that power. Today, responsibility calls for vigilance about what changes we adopt. I am communicating these thoughts as part of my ongoing effort to ensure Bitcoin remains future-proof. “Future-proofing” Bitcoin doesn’t just mean scaling it or boosting hash rate; it also means safeguarding its social acceptance and moral foundation. By voicing dissent, by switching implementations, by potentially forking if needed, we the users are stress-testing Bitcoin’s resilience in exactly the way it was designed to be: from the bottom up.

Bitcoin’s story has always been about empowerment of the individual. This current saga, the Node Wars over OP_RETURN and content, is yet another chapter in that story. I, for one, am determined to see Bitcoin thrive as a tool of financial liberation, unsullied by association with illicit content. It may ruffle feathers now, but principled stances often do. As the saying goes, “Bitcoin is for enemies”, but that doesn’t mean we have to let enemies turn it against us. My hope is that through self-sovereign action and frank dialogue, we will navigate this challenge and emerge with a Bitcoin network that is both freer and more secure, a network that can confidently serve the world for decades to come, without any shadow of disgrace on its ledger.

The choice is in front of us. By October 2025, Bitcoin Core v30 will normalise the relaying of arbitrary, potentially illicit content across the network. If we do nothing, if we keep quiet, then we silently consent to this shift. As Bitcoiners, we must ask ourselves: do we want our blockchain remembered as the foundation of sound money, or as a storage ground for abuse?

I’ve made my decision, I run Bitcoin Knots, I reject services that endorse Core v30, and I will defend a “clean” Bitcoin that remains worthy of global trust. The question is: what kind of Bitcoin are you willing to stand behind?

I’m far from alone in this choice. As mentioned, a substantial minority of node operators are switching to Knots or sticking with older Core versions. This grass roots movement is reminiscent of how users can enforce their preferences in Bitcoin – much like the User Activated Soft Fork (UASF) concept, node runners can ‘vote’ by choosing which software to run. If enough of us reject Core v30, it could create economic incentives for miners to think twice about stuffing blocks with junk that a portion of the network won’t relay or perhaps even accept. (To be clear, Knots today does accept blocks created under Core’s new rules – it’s not a hard fork. The divergence is in relay policy and default behaviour, not consensus rules. This is a fight being waged via network policy, not chain splits… at least not yet.)

Self-sovereignty also means accepting personal responsibility for what I support in the network. That extends beyond just the software I run. It also influences my choices as a customer and community member. In light of the OP_RETURN controversy, I have decided on a few concrete actions, which I’ll outline here:

Running a “clean” node: I’ve migrated all my nodes to Bitcoin Knots and will continue to do so for the foreseeable future. This ensures that I am not propagating or validating illicit data beyond the absolute minimum required by consensus. If a bloated transaction or block crosses my node, Knots’ policies will treat it with the maximum strictness allowed (dropping it from mempool if possible, and certainly not relaying such transactions to peers). This is my way of keeping my corner of the Bitcoin network as clean of illicit content as possible. It’s a personal stand: I do not want even the chance of illegal material passing through my machine.

Boycotting services that endorse Core v30: I am discontinuing my use of any exchanges, custodians, or Bitcoin companies that I know are upgrading to or support the Core v30 software without protest. For example, if a company like River Financial or a tech firm like Blockstream chooses to run Core v30 nodes (thus knowingly accepting the relay of unlimited content, illicit or otherwise), then I will not be doing business with them. Those organizations might trust their lawyers or regulators to sort out the fallout of hosting illicit data on their nodes – that’s their prerogative. But I cannot in good conscience support institutions that, in my view, are inviting a flood of abusive content onto the Bitcoin blockchain and risking its reputation. My money and support will go to those who keep Bitcoin robust and respectable.

Advocating for a “clean” Bitcoin (even if it means a fork): Looking ahead, I suspect that other major players in the Bitcoin ecosystem share my concern, even if they aren’t voicing it loudly yet. Think of large public companies holding Bitcoin in their treasuries, or firms planning Bitcoin ETFs. The last thing these institutions want is to be entangled with a network that could inadvertently facilitate the spread of illegal content. It’s not hard to imagine some of them drawing a line: if Bitcoin’s protocol won’t address this problem, they might resort to extraordinary measures. This could include supporting a hard fork to create a “clean” version of Bitcoin that excises or filters out illicit material. BlackRock, for instance, is on the cusp of launching a spot Bitcoin ETF. In BlackRock’s own filings, they note that in the event of a fork, they have full discretion to decide which chain to consider the “real” Bitcoin for their fund.That means if a new fork gained momentum – say, a Bitcoin variant with strict protocol rules against arbitrary data – BlackRock could opt to adopt it for their ETF (or conversely, to abandon a chain that becomes too toxic). While this scenario sounds extreme, it’s entirely within the realm of possibility. The very fact that we’re discussing child pornography on the blockchain may prompt powerful stakeholders to assert control to protect their investments. I’m not actively calling for an immediate fork, that’s a complex, last-resort path, but I do believe that if Bitcoin Core’s path leads to legal quagmires, the market will find a way to course-correct, even if it means a chain split. My hope is that by raising awareness now, we can avert such drastic outcomes. But make no mistake: Bitcoin’s future must not include being a playground for criminal content, and I’ll support any serious effort to ensure that.

Bitcoin’s Future: Balancing Freedom and Responsibility

The controversy over OP_RETURN and illicit content forces an uncomfortable but necessary conversation about the future we want for Bitcoin. On one side is the ideal of total neutrality, Bitcoin as an unfilterable, permissionless ledger where “code is law” and even questionable data is just data. On the other side is the recognition that Bitcoin does not exist in a vacuum: if we undermine its primary use case as money or subject its participants to legal peril, we could kill the proverbial goose that lays the golden eggs. Finding the right balance is tricky. We cherish Bitcoin’s censorship-resistance precisely because it protects financial freedom and speech. Yet, does rejecting any filtering, even of grotesquely abusive content, truly serve the cause of freedom? Or does it hand enemies of Bitcoin the very weapon they need to attack it? These are challenging questions, and reasonable people in the community answer them differently.

For me, the answer comes back to self-sovereignty and consent. I did not sign up to store illicit images or arbitrary gigabytes of data on my node, that’s not the social contract under which I joined Bitcoin. My consent as a node operator matters. True decentralisation means we, the users get to collectively decide what the blockchain is for, by either running or not running certain code. It’s heartening to see that even Core developers acknowledge this in principle: “If Bitcoin Core’s contributors ever abandon [Bitcoin’s core] values… the community will switch to another node implementation that does it better,” wrote Gloria Zhao amidst the debate. I’d argue that forcing nodes to relay and store unlimited junk (with potentially ghastly contents) is a departure from the values that brought many of us to Bitcoin. And indeed, we’re seeing the community vote with its feet, or rather with its node software.

Moving forward, I believe Bitcoin will be stress-tested on this front. The coming months and years will reveal whether the network can accommodate new use-cases (like data inscriptions) without losing its soul – or whether a correction is needed. Perhaps Bitcoin Core’s gambit will pay off: maybe the “spam” will remain manageable, new pruning techniques will mitigate the bloat, and no criminal will attempt to abuse the blockchain’s openness. In that best case, my concerns would be eased (and I’d gladly acknowledge an overabundance of caution on my part). But if the worst case materialises, if obscene data starts showing up in blocks, if typical users find the chain clogged with non-financial data, if governments use this as a cudgel – then the community must be ready to respond decisively. Hard forks have happened before in Bitcoin’s history when values were at stake (recall the split that created Bitcoin Cash in 2017 over a blocksize dispute). A fork to preserve Bitcoin’s legal cleanliness and focused mission might become not just acceptable but essential to “future-proof” the network. And unlike a protocol tweak coming from a small group, a community or institution-driven fork would reflect a broad consensus that Bitcoin as it was is worth defending. BlackRock and other institutional players entering the space could ironically become allies in keeping Bitcoin safe for mainstream use – they will not tolerate holding an asset tainted by crime, so they have every incentive to back a solution, even if it’s a controversial one.

Conclusion: Upholding Bitcoin’s Integrity

In closing, my stance can be distilled to this: Bitcoin’s strength lies in our ability to choose and enforce the rules that best uphold the network’s purpose and integrity. As a self-sovereign participant, I choose to reject the notion that Bitcoin must accept everything in the name of “freedom,” especially when that freedom can be cynically exploited to Bitcoin’s detriment. Instead, I align with the principle that some judicious constraints, whether at the software policy level or the community social level, are necessary to keep Bitcoin healthy, useful, and legally accessible to all. This is a nuanced position, and it may be polarising. Some will accuse me of advocating “censorship” or betraying Bitcoin’s neutrality. I respect the purist viewpoint, but I humbly disagree in this case. Refusing to store illegal content is not tyranny; it’s common sense. We can defend freedom of transaction without turning Bitcoin into a sanctuary for the worst humanity has to offer.

In my book on self-sovereignty, I wrote that with great power comes great responsibility, running a Bitcoin node is indeed powerful, and it’s up to each of us to act responsibly with that power. Today, responsibility calls for vigilance about what changes we adopt. I am communicating these thoughts as part of my ongoing effort to ensure Bitcoin remains future-proof. “Future-proofing” Bitcoin doesn’t just mean scaling it or boosting hash rate; it also means safeguarding its social acceptance and moral foundation. By voicing dissent, by switching implementations, by potentially forking if needed, we the users are stress-testing Bitcoin’s resilience in exactly the way it was designed to be: from the bottom up.

Bitcoin’s story has always been about empowerment of the individual. This current saga, the Node Wars over OP_RETURN and content, is yet another chapter in that story. I, for one, am determined to see Bitcoin thrive as a tool of financial liberation, unsullied by association with illicit content. It may ruffle feathers now, but principled stances often do. As the saying goes, “Bitcoin is for enemies”, but that doesn’t mean we have to let enemies turn it against us. My hope is that through self-sovereign action and frank dialogue, we will navigate this challenge and emerge with a Bitcoin network that is both freer and more secure, a network that can confidently serve the world for decades to come, without any shadow of disgrace on its ledger.

The choice is in front of us. By October 2025, Bitcoin Core v30 will normalise the relaying of arbitrary, potentially illicit content across the network. If we do nothing, if we keep quiet, then we silently consent to this shift. As Bitcoiners, we must ask ourselves: do we want our blockchain remembered as the foundation of sound money, or as a storage ground for abuse?

I’ve made my decision, I run Bitcoin Knots, I reject services that endorse Core v30, and I will defend a “clean” Bitcoin that remains worthy of global trust. The question is: what kind of Bitcoin are you willing to stand behind?

Building Life Brick by Brick on Bitcoin

Bitcoin just reached a new all-time high. For most people, that’s a moment of excitement, a rush of adrenaline, a headline, a chart snapshot to post or debate. But for me, it’s something entirely different.

Bitcoin hitting a new all-time high doesn’t trigger greed, FOMO, or regret in me anymore. Instead, it reminds me why I chose this path.

I’m grateful to live on a Bitcoin standard. I’m thankful that I already made the decision years ago. I’m proud I stuck to my principles through the noise, the doubt, and the mockery. I feel sovereign in a world where most people are still trapped in uncertainty.

While others are panicking, flexing, or speculating… …I simply breathe. I observe. I smile.

Because Bitcoin’s price going up doesn’t change anything fundamental, it just reveals what’s already true. It’s the world slowly catching up to an idea I’ve been living for years: that real wealth is measured in freedom, not in fiat.

The All-Time High as a Mirror

Every new all-time high acts like a psychological mirror. It reflects who we are and where we stand in our journey toward sovereignty.

Some will feel regret, “I should have bought more.” Some will feel greed, “I need to take profit before it crashes.” And some will simply feel validation, “See, I told you so.”

But when you live on a Bitcoin standard rather than just with Bitcoin, your emotional compass shifts. You stop reacting to price, and you start observing yourself.

“Sovereignty is not a moment of rebellion; it’s a habit of responsibility.” (Excerpt from Brick by Brick: Building a Sovereign Life on Bitcoin)

That line captures what I’ve learned over years of trial, study, and reflection. The journey toward sovereignty isn’t made of radical leaps, it’s built brick by brick, through consistent discipline and conscious choice. Every day you hold your keys, question the system, or build something of your own, you add another layer to your foundation of freedom.

Beyond Price, The Inner Revolution

This new all-time high is not just a milestone for Bitcoin; it’s a mirror for humanity. It tells us less about markets and more about mindset. Bitcoin’s volatility exposes our conditioning, how deeply we’ve internalized fiat thinking. In the fiat world, price defines value. In the Bitcoin world, principle defines value. That shift, from external metrics to internal conviction, is the quiet revolution happening beneath every orange candle.

In Brick by Brick, I write:

“The more you disconnect from fiat thinking, the more you reconnect with yourself.”

Living on a Bitcoin standard changed how I eat, think, and plan. It’s not about chasing highs, it’s about building a system that can’t be taken from you. It’s about finding clarity amid chaos, patience amid noise, and conviction amid confusion.

October 31 - A Date with Meaning

On October 31, Bitcoiners around the world celebrate the release of the Bitcoin White Paper, the blueprint for decentralized freedom. This year, that same day will also mark the release of my book, Brick by Brick: Building a Sovereign Life on Bitcoin.

\ Amazon: https://amzn.to/4gYknKb

Website: https://twentyone.life/

It’s both a tribute and a continuation, a reflection on how Bitcoin reshapes our understanding of money, health, technology, and self-sovereignty. Each chapter explores how the fiat system distorts incentives, weakens resilience, and disconnects us from reality, and how Bitcoiners are rebuilding from the ground up.

It’s not just a book about Bitcoin, it’s a manual for living freely in a controlled world.

The Fiat Price Is Just the World Catching Up

When Bitcoin breaks records, I don’t celebrate in numbers, I celebrate in meaning. Because the fiat price doesn’t reveal Bitcoin’s worth; it reveals how many people are finally beginning to understand it.

Excerpt from Brick by Brick: Building a Sovereign Life on Bitcoin

The journey has never been about predicting when Bitcoin moons, it’s about knowing who you are when it does. I don’t chase markets anymore. I build foundations. And every brick I lay, in my habits, my systems, my thoughts, reinforces that freedom is something you live, not something you buy.

🔥 From Noise to Sovereignty - Visualizing the Shift to Bitcoin 🔥

Just wrapped a full series of Bitcoin-orange illustrations that tell one story:

Introduction: A New Controversy in Bitcoin’s Evolution

If you hold Bitcoin, if you call yourself a Bitcoiner, are you prepared to accept that the Bitcoin blockchain could be used to store illicit, even illegal content? This isn’t a hypothetical. Unless we act, by October 2025 the default Bitcoin Core software will make this the new reality. And if you don’t react now, your silence means acceptance.

Bitcoin is facing a pivotal controversy that cuts to the heart of its identity. The debate centres on a proposed change in Bitcoin’s core software that would remove longstanding limits on storing arbitrary data in transactions. On the surface, this change sounds technical – raising the OP_RETURN data limit from 80 bytes to nearly 4 megabytes, but its implications are profoundly human. Supporters hail it as an overdue embrace of censorship-resistance, while critics warn it could turn the blockchain into a host for illegal or abusive content. As a Bitcoiner who champions self-sovereignty and Bitcoin’s reputation as sound money, I find myself firmly in the latter camp. This article, written from my personal perspective and drawing on my book’s focus (Brick by Brick - <https://twentyone.life/brick-by-brick>) on self-sovereignty, explores why I’m taking a stand by running alternative software and even boycotting certain services, all in the name of a “clean” future for Bitcoin.

Background: Bitcoin Core v30 and the OP_RETURN Debate

At issue is a change slated for the upcoming Bitcoin Core version 30 (expected October 2025). Bitcoin Core is the dominant software for running nodes (over 75% of nodes run so its defaults largely define network behaviour. The core developers have decided to unshackle the OP_RETURN field, which historically allowed embedding only a tiny piece of data (≤83 bytes) in a transaction. This limit acted as a de facto “spam filter”, discouraging users from turning Bitcoin’s ledger into a generic data storage system.

Under Core v30, that filter is being removed entirely: users will be able to attach much larger data payloads, up to the size of a full block (~4MB), in a single transaction output. Moreover, Bitcoin Core will eliminate the configuration options (data carrier settings) that previously let node operators refuse relaying big OP_RETURN transactions. In short, the new default policy is “anything goes” for data, and individual node runners won’t easily opt out. While v30 still offers command-line tweaks to impose custom limits, those are now deprecated warnings likely to be removed later.

Why make this change? Proponents argue it’s a pragmatic response to reality. The 80-byte cap, they say, has been routinely bypassed by creative users who already insert larger data through other means – for example, using Taproot witness data or fake outputs (as seen in the 2023 Ordinals/“inscriptions” craze that let people embed images and art on Bitcoin). These workarounds are actually worse for the network: since the data is hidden in spendable outputs or witness scripts, it can bloat the UTXO set (the list of unspent coins) and increase validation costs for all nodes. By contrast, OP_RETURN outputs are provably unspendable and easily prunable. In the eyes of Core developers, it’s better to let people put data in OP_RETURN (where it doesn’t harm UTXO or decentralisation) than to have them continue abusing more harmful trick. Removing the cap “yields at least two tangible benefits: a cleaner UTXO set and more consistent default behaviour,” explained developer Greg Sanders. The change also aligns with Bitcoin’s values of neutrality, if a transaction is valid and pays the fee, who are nodes to censor it? Core maintainers like Gloria Zhao argue that trying to filter transactions at the node level is futile and against the principle of censorship-resistance.

On the other side, critics are alarmed. They counter that dropping these limits will open the floodgates to arbitrary data, fundamentally altering Bitcoin’s purpose. The blockchain could become a bloated “immutable database” of random content, potentially crowding out financial transactions with higher fees and diluting Bitcoin’s use as peer-to-peer money. What’s more, unbounded data storage invites spam, people could stuff blocks with endless memes, ads, or junk simply because they’re willing to pay. It’s a replay of the Blocksize War arguments, but instead of bigger blocks for payments, it’s bigger payloads for non-monetary data. The community is starkly divided: should Bitcoin evolve to support broader use cases (data, NFTs, digital artifacts), or should it resist becoming a free-for-all content repository and stick to financial utility? These positions are diametrically opposed, and the conflict has been heated – drawing comparisons to the acrimony of the 2017 blocksize debates.

Notably, longtime Bitcoin developer Luke Dashjr (author of an alternative client called Bitcoin Knots - https://x.com/LukeDashjr) has been one of the most vocal opponents besides Bitcoin Mechanic and Bitcoin University ( primal.net/kratter). He warns that the removal of what he bluntly calls “spam filters” is potentially harmful to the network and its users. Dashjr has publicly urged node operators to avoid upgrading to Core v30 or to switch to alternative software like Bitcoin Knots. In fact, many Bitcoiners have already acted on that advice. When the OP_RETURN plan was announced and fast-tracked earlier this year, there was a surge of users migrating their nodes from Core to Knots, by some estimates, over 15% of previously Core nodes switched to Bitcoin Knots in protest. The stage is set for a grass-roots pushback using Bitcoin’s own strength: decentralisation. True to the mantra of self-sovereignty, if you disagree with the default rules, you are free to run a node that reflects your values. I count myself among those taking that step.

Illicit Content on the Blockchain: The Serious Risks

Why am I, and others, so concerned about lifting the data limits? Because it’s not just “cute cat pictures” or art collections that could find their way onto Bitcoin’s ledger. The most dire possibility is the inclusion of illicit and abusive content in an immutable, globally replicated chain. This isn’t idle paranoia; it’s a genuine risk recognised by both sides of the debate. Even the advocates of OP_RETURN freedom acknowledge the “undesirable second-order effects” that could follow. Let’s spell it out: What if someone starts embedding child sexual abuse material (CSAM) or other illegal data in Bitcoin transactions? Once mined into a block, that content is there forever, every full node would unknowingly host it on their hard drive as part of the blockchain spreaded on tens of thousands nodes across the world. This scenario is a nightmare for obvious moral reasons, and it also poses a legal and reputational threat to anyone running a node or the Bitcoin network as a whole. Besides this, to spin up a new node will take longer and need higher technical hardware which leads to centralisation.

Unfortunately, the threat is not theoretical. It has already happened on a small scale. Researchers have found that forbidden content made its way onto Bitcoin as early as 2013, albeit in an obscure form. In 2018, a paper famously claimed that Bitcoin’s blockchain contained links to child pornography; at the time, critics dismissed it as sensationalism since only a few bytes of encoded data were involved and Core’s filters limited further abuse. But today we’re looking at a very different landscape. The data per block is increasing dramatically with the new policy. A concerned Bitcoiner known as “Bitcoin Mechanic” ( primal.net/p/nprofile1qqs8fl79rnpsz5x00xmvkvtd8g2u7ve2k2dr3lkfadyy4v24r4k3s4sh8dmel) recently warned that removing the filter “will draw unforeseen consequences,” meaning content like child pornography can appear on the Bitcoin blockchain” once v30 goes live. His point is straightforward: if you give bad actors the ability to inject large payloads, someone will inevitably push the worst kind of content into the system. And perversely, there’s a twisted incentive for them to do so: “Getting other people to store it for you is vastly preferable to storing it yourself,” Mechanic notes, what better way for criminals to disseminate vile material than piggyback on tens of thousands of innocent Bitcoin nodes?

Core developers have responded that these fears may be overblown. They often cite examples of other blockchains (for instance, Monero or Ethereum) that don’t have such data limits yet haven’t become overrun with illegal content. They stress that Bitcoin’s permissionless nature means anything could be written to it, but that doesn’t mean an epidemic of criminal data is imminent. Perhaps, but I would counter that Bitcoin’s global prominence and immutable design make it a uniquely attractive target for someone trying to cause chaos or discredit the system. It only takes one high-profile incident of truly heinous content on Bitcoin to unleash a regulatory crackdown. Remember, Bitcoin’s censorship-resistance cuts both ways: it empowers individuals, but it also neutralises traditional controls, which is exactly why governments get antsy when crimes enter the mix.

The legal implications of this are untested and scary. If a Bitcoin block contains illegal pornography or violent propaganda, could authorities argue that every node operator is technically in possession of contraband data? Some in the community worry that, yes, this could give governments a “perfect excuse to outlaw Bitcoin or make running a node illegal”. Even if that outcome is unlikely in jurisdictions that understand how Bitcoin works, the mere perception that Bitcoin is hosting criminal content would be a PR disaster. It would hand ammunition to anti-crypto politicians and could make regulators slam the brakes on adoption. As a Bitcoiner who wants to see this technology thrive, I find that risk unacceptable. Bitcoin’s social contract might be robust against internal dissent, but it’s not immune to external legal attack. Preserving Bitcoin’s integrity means ensuring it doesn’t become synonymous with “dark web file storage” in the public eye.

Embracing Self-Sovereignty: Why I Run Bitcoin Knots

My response to this situation has been guided by one of Bitcoin’s core principles: self-sovereignty. In essence, self-sovereignty means taking full ownership of your participation in the network, holding your own keys, and running your own node with the rules you choose. In the book I authored on Bitcoin and self-sovereign principles, I emphasised that running a node is more than a technical task; it’s an expression of personal agency and values. Now, faced with Bitcoin Core’s direction that I deeply disagree with, I’m putting that ethos into practice.

For the past four months, I have been running Bitcoin Knots instead of the standard Bitcoin Core software. Bitcoin Knots is a well-established alternative client (maintained by Luke Dashjr) that, in many ways, is identical to Core except for a few important differences, notably, Knots retains stricter limits on OP_RETURN data and gives the user full control over relay filters. In fact, Knots by default still caps OP_RETURN at 40 bytes (the old limit from years ago) and allows only one OP_RETURN output per transaction. It’s basically “Bitcoin Core, but with the spam filter intact.” By running Knots, my node will not relay or mine the kind of oversized data-storing transactions that Core v30 endorses. More importantly, it signals my support for a vision of Bitcoin that prioritises financial transactions over arbitrary data. Knots users (myself included) see ourselves as defending Bitcoin’s integrity from a controversial experiment. We are effectively saying, “Not on my node!” when it comes to turning Bitcoin into an uncensored data dump.

I’m far from alone in this choice. As mentioned, a substantial minority of node operators are switching to Knots or sticking with older Core versions. This grass roots movement is reminiscent of how users can enforce their preferences in Bitcoin – much like the User Activated Soft Fork (UASF) concept, node runners can ‘vote’ by choosing which software to run. If enough of us reject Core v30, it could create economic incentives for miners to think twice about stuffing blocks with junk that a portion of the network won’t relay or perhaps even accept. (To be clear, Knots today does accept blocks created under Core’s new rules – it’s not a hard fork. The divergence is in relay policy and default behaviour, not consensus rules. This is a fight being waged via network policy, not chain splits… at least not yet.)

Self-sovereignty also means accepting personal responsibility for what I support in the network. That extends beyond just the software I run. It also influences my choices as a customer and community member. In light of the OP_RETURN controversy, I have decided on a few concrete actions, which I’ll outline here:

Running a “clean” node: I’ve migrated all my nodes to Bitcoin Knots and will continue to do so for the foreseeable future. This ensures that I am not propagating or validating illicit data beyond the absolute minimum required by consensus. If a bloated transaction or block crosses my node, Knots’ policies will treat it with the maximum strictness allowed (dropping it from mempool if possible, and certainly not relaying such transactions to peers). This is my way of keeping my corner of the Bitcoin network as clean of illicit content as possible. It’s a personal stand: I do not want even the chance of illegal material passing through my machine.

Boycotting services that endorse Core v30: I am discontinuing my use of any exchanges, custodians, or Bitcoin companies that I know are upgrading to or support the Core v30 software without protest. For example, if a company like River Financial or a tech firm like Blockstream chooses to run Core v30 nodes (thus knowingly accepting the relay of unlimited content, illicit or otherwise), then I will not be doing business with them. Those organizations might trust their lawyers or regulators to sort out the fallout of hosting illicit data on their nodes – that’s their prerogative. But I cannot in good conscience support institutions that, in my view, are inviting a flood of abusive content onto the Bitcoin blockchain and risking its reputation. My money and support will go to those who keep Bitcoin robust and respectable.

Advocating for a “clean” Bitcoin (even if it means a fork): Looking ahead, I suspect that other major players in the Bitcoin ecosystem share my concern, even if they aren’t voicing it loudly yet. Think of large public companies holding Bitcoin in their treasuries, or firms planning Bitcoin ETFs. The last thing these institutions want is to be entangled with a network that could inadvertently facilitate the spread of illegal content. It’s not hard to imagine some of them drawing a line: if Bitcoin’s protocol won’t address this problem, they might resort to extraordinary measures. This could include supporting a hard fork to create a “clean” version of Bitcoin that excises or filters out illicit material. BlackRock, for instance, is on the cusp of launching a spot Bitcoin ETF. In BlackRock’s own filings, they note that in the event of a fork, they have full discretion to decide which chain to consider the “real” Bitcoin for their fund.That means if a new fork gained momentum – say, a Bitcoin variant with strict protocol rules against arbitrary data – BlackRock could opt to adopt it for their ETF (or conversely, to abandon a chain that becomes too toxic). While this scenario sounds extreme, it’s entirely within the realm of possibility. The very fact that we’re discussing child pornography on the blockchain may prompt powerful stakeholders to assert control to protect their investments. I’m not actively calling for an immediate fork, that’s a complex, last-resort path, but I do believe that if Bitcoin Core’s path leads to legal quagmires, the market will find a way to course-correct, even if it means a chain split. My hope is that by raising awareness now, we can avert such drastic outcomes. But make no mistake: Bitcoin’s future must not include being a playground for criminal content, and I’ll support any serious effort to ensure that.

Bitcoin’s Future: Balancing Freedom and Responsibility

The controversy over OP_RETURN and illicit content forces an uncomfortable but necessary conversation about the future we want for Bitcoin. On one side is the ideal of total neutrality, Bitcoin as an unfilterable, permissionless ledger where “code is law” and even questionable data is just data. On the other side is the recognition that Bitcoin does not exist in a vacuum: if we undermine its primary use case as money or subject its participants to legal peril, we could kill the proverbial goose that lays the golden eggs. Finding the right balance is tricky. We cherish Bitcoin’s censorship-resistance precisely because it protects financial freedom and speech.

A fork to preserve Bitcoin’s legal cleanliness and focused mission might become not just acceptable but essential to “future-proof” the network. And unlike a protocol tweak coming from a small group, a community or institution-driven fork would reflect a broad consensus that Bitcoin as it was is worth defending. BlackRock and other institutional players entering the space could ironically become allies in keeping Bitcoin safe for mainstream use – they will not tolerate holding an asset tainted by crime, so they have every incentive to back a solution, even if it’s a controversial one.

Conclusion: Upholding Bitcoin’s Integrity

In closing, my stance can be distilled to this: Bitcoin’s strength lies in our ability to choose and enforce the rules that best uphold the network’s purpose and integrity. As a self-sovereign participant, I choose to reject the notion that Bitcoin must accept everything in the name of “freedom,” especially when that freedom can be cynically exploited to Bitcoin’s detriment. Instead, I align with the principle that some judicious constraints, whether at the software policy level or the community social level, are necessary to keep Bitcoin healthy, useful, and legally accessible to all. This is a nuanced position, and it may be polarising. Some will accuse me of advocating “censorship” or betraying Bitcoin’s neutrality. I respect the purist viewpoint, but I humbly disagree in this case. Refusing to store illegal content is not tyranny; it’s common sense. We can defend freedom of transaction without turning Bitcoin into a sanctuary for the worst humanity has to offer.

In my book on self-sovereignty, I wrote that with great power comes great responsibility, running a Bitcoin node is indeed powerful, and it’s up to each of us to act responsibly with that power. Today, responsibility calls for vigilance about what changes we adopt. I am communicating these thoughts as part of my ongoing effort to ensure Bitcoin remains future-proof. “Future-proofing” Bitcoin doesn’t just mean scaling it or boosting hash rate; it also means safeguarding its social acceptance and moral foundation. By voicing dissent, by switching implementations, by potentially forking if needed, we the users are stress-testing Bitcoin’s resilience in exactly the way it was designed to be: from the bottom up.

Bitcoin’s story has always been about empowerment of the individual. This current saga, the Node Wars over OP_RETURN and content, is yet another chapter in that story. I, for one, am determined to see Bitcoin thrive as a tool of financial liberation, unsullied by association with illicit content. It may ruffle feathers now, but principled stances often do. As the saying goes, “Bitcoin is for enemies”, but that doesn’t mean we have to let enemies turn it against us. My hope is that through self-sovereign action and frank dialogue, we will navigate this challenge and emerge with a Bitcoin network that is both freer and more secure, a network that can confidently serve the world for decades to come, without any shadow of disgrace on its ledger.

The choice is in front of us. By October 2025, Bitcoin Core v30 will normalise the relaying of arbitrary, potentially illicit content across the network. If we do nothing, if we keep quiet, then we silently consent to this shift. As Bitcoiners, we must ask ourselves: do we want our blockchain remembered as the foundation of sound money, or as a storage ground for abuse?

I’ve made my decision, I run Bitcoin Knots, I reject services that endorse Core v30, and I will defend a “clean” Bitcoin that remains worthy of global trust. The question is: what kind of Bitcoin are you willing to stand behind?

Introduction: A New Controversy in Bitcoin’s Evolution

If you hold Bitcoin, if you call yourself a Bitcoiner, are you prepared to accept that the Bitcoin blockchain could be used to store illicit, even illegal content? This isn’t a hypothetical. Unless we act, by October 2025 the default Bitcoin Core software will make this the new reality. And if you don’t react now, your silence means acceptance.

Bitcoin is facing a pivotal controversy that cuts to the heart of its identity. The debate centres on a proposed change in Bitcoin’s core software that would remove longstanding limits on storing arbitrary data in transactions. On the surface, this change sounds technical – raising the OP_RETURN data limit from 80 bytes to nearly 4 megabytes, but its implications are profoundly human. Supporters hail it as an overdue embrace of censorship-resistance, while critics warn it could turn the blockchain into a host for illegal or abusive content. As a Bitcoiner who champions self-sovereignty and Bitcoin’s reputation as sound money, I find myself firmly in the latter camp. This article, written from my personal perspective and drawing on my book’s focus (Brick by Brick - <https://twentyone.life/brick-by-brick>) on self-sovereignty, explores why I’m taking a stand by running alternative software and even boycotting certain services, all in the name of a “clean” future for Bitcoin.

Background: Bitcoin Core v30 and the OP_RETURN Debate

At issue is a change slated for the upcoming Bitcoin Core version 30 (expected October 2025). Bitcoin Core is the dominant software for running nodes (over 75% of nodes run so its defaults largely define network behaviour. The core developers have decided to unshackle the OP_RETURN field, which historically allowed embedding only a tiny piece of data (≤83 bytes) in a transaction. This limit acted as a de facto “spam filter”, discouraging users from turning Bitcoin’s ledger into a generic data storage system.

Under Core v30, that filter is being removed entirely: users will be able to attach much larger data payloads, up to the size of a full block (~4MB), in a single transaction output. Moreover, Bitcoin Core will eliminate the configuration options (data carrier settings) that previously let node operators refuse relaying big OP_RETURN transactions. In short, the new default policy is “anything goes” for data, and individual node runners won’t easily opt out. While v30 still offers command-line tweaks to impose custom limits, those are now deprecated warnings likely to be removed later.

Why make this change? Proponents argue it’s a pragmatic response to reality. The 80-byte cap, they say, has been routinely bypassed by creative users who already insert larger data through other means – for example, using Taproot witness data or fake outputs (as seen in the 2023 Ordinals/“inscriptions” craze that let people embed images and art on Bitcoin). These workarounds are actually worse for the network: since the data is hidden in spendable outputs or witness scripts, it can bloat the UTXO set (the list of unspent coins) and increase validation costs for all nodes. By contrast, OP_RETURN outputs are provably unspendable and easily prunable. In the eyes of Core developers, it’s better to let people put data in OP_RETURN (where it doesn’t harm UTXO or decentralisation) than to have them continue abusing more harmful trick. Removing the cap “yields at least two tangible benefits: a cleaner UTXO set and more consistent default behaviour,” explained developer Greg Sanders. The change also aligns with Bitcoin’s values of neutrality, if a transaction is valid and pays the fee, who are nodes to censor it? Core maintainers like Gloria Zhao argue that trying to filter transactions at the node level is futile and against the principle of censorship-resistance.

On the other side, critics are alarmed. They counter that dropping these limits will open the floodgates to arbitrary data, fundamentally altering Bitcoin’s purpose. The blockchain could become a bloated “immutable database” of random content, potentially crowding out financial transactions with higher fees and diluting Bitcoin’s use as peer-to-peer money. What’s more, unbounded data storage invites spam, people could stuff blocks with endless memes, ads, or junk simply because they’re willing to pay. It’s a replay of the Blocksize War arguments, but instead of bigger blocks for payments, it’s bigger payloads for non-monetary data. The community is starkly divided: should Bitcoin evolve to support broader use cases (data, NFTs, digital artifacts), or should it resist becoming a free-for-all content repository and stick to financial utility? These positions are diametrically opposed, and the conflict has been heated – drawing comparisons to the acrimony of the 2017 blocksize debates.

Notably, longtime Bitcoin developer Luke Dashjr (author of an alternative client called Bitcoin Knots - https://x.com/LukeDashjr) has been one of the most vocal opponents besides Bitcoin Mechanic and Bitcoin University ( primal.net/kratter). He warns that the removal of what he bluntly calls “spam filters” is potentially harmful to the network and its users. Dashjr has publicly urged node operators to avoid upgrading to Core v30 or to switch to alternative software like Bitcoin Knots. In fact, many Bitcoiners have already acted on that advice. When the OP_RETURN plan was announced and fast-tracked earlier this year, there was a surge of users migrating their nodes from Core to Knots, by some estimates, over 15% of previously Core nodes switched to Bitcoin Knots in protest. The stage is set for a grass-roots pushback using Bitcoin’s own strength: decentralisation. True to the mantra of self-sovereignty, if you disagree with the default rules, you are free to run a node that reflects your values. I count myself among those taking that step.

Illicit Content on the Blockchain: The Serious Risks

Why am I, and others, so concerned about lifting the data limits? Because it’s not just “cute cat pictures” or art collections that could find their way onto Bitcoin’s ledger. The most dire possibility is the inclusion of illicit and abusive content in an immutable, globally replicated chain. This isn’t idle paranoia; it’s a genuine risk recognised by both sides of the debate. Even the advocates of OP_RETURN freedom acknowledge the “undesirable second-order effects” that could follow. Let’s spell it out: What if someone starts embedding child sexual abuse material (CSAM) or other illegal data in Bitcoin transactions? Once mined into a block, that content is there forever, every full node would unknowingly host it on their hard drive as part of the blockchain spreaded on tens of thousands nodes across the world. This scenario is a nightmare for obvious moral reasons, and it also poses a legal and reputational threat to anyone running a node or the Bitcoin network as a whole. Besides this, to spin up a new node will take longer and need higher technical hardware which leads to centralisation.

Unfortunately, the threat is not theoretical. It has already happened on a small scale. Researchers have found that forbidden content made its way onto Bitcoin as early as 2013, albeit in an obscure form. In 2018, a paper famously claimed that Bitcoin’s blockchain contained links to child pornography; at the time, critics dismissed it as sensationalism since only a few bytes of encoded data were involved and Core’s filters limited further abuse. But today we’re looking at a very different landscape. The data per block is increasing dramatically with the new policy. A concerned Bitcoiner known as “Bitcoin Mechanic” ( primal.net/p/nprofile1qqs8fl79rnpsz5x00xmvkvtd8g2u7ve2k2dr3lkfadyy4v24r4k3s4sh8dmel) recently warned that removing the filter “will draw unforeseen consequences,” meaning content like child pornography can appear on the Bitcoin blockchain” once v30 goes live. His point is straightforward: if you give bad actors the ability to inject large payloads, someone will inevitably push the worst kind of content into the system. And perversely, there’s a twisted incentive for them to do so: “Getting other people to store it for you is vastly preferable to storing it yourself,” Mechanic notes, what better way for criminals to disseminate vile material than piggyback on tens of thousands of innocent Bitcoin nodes?

Core developers have responded that these fears may be overblown. They often cite examples of other blockchains (for instance, Monero or Ethereum) that don’t have such data limits yet haven’t become overrun with illegal content. They stress that Bitcoin’s permissionless nature means anything could be written to it, but that doesn’t mean an epidemic of criminal data is imminent. Perhaps, but I would counter that Bitcoin’s global prominence and immutable design make it a uniquely attractive target for someone trying to cause chaos or discredit the system. It only takes one high-profile incident of truly heinous content on Bitcoin to unleash a regulatory crackdown. Remember, Bitcoin’s censorship-resistance cuts both ways: it empowers individuals, but it also neutralises traditional controls, which is exactly why governments get antsy when crimes enter the mix.

The legal implications of this are untested and scary. If a Bitcoin block contains illegal pornography or violent propaganda, could authorities argue that every node operator is technically in possession of contraband data? Some in the community worry that, yes, this could give governments a “perfect excuse to outlaw Bitcoin or make running a node illegal”. Even if that outcome is unlikely in jurisdictions that understand how Bitcoin works, the mere perception that Bitcoin is hosting criminal content would be a PR disaster. It would hand ammunition to anti-crypto politicians and could make regulators slam the brakes on adoption. As a Bitcoiner who wants to see this technology thrive, I find that risk unacceptable. Bitcoin’s social contract might be robust against internal dissent, but it’s not immune to external legal attack. Preserving Bitcoin’s integrity means ensuring it doesn’t become synonymous with “dark web file storage” in the public eye.

Embracing Self-Sovereignty: Why I Run Bitcoin Knots

My response to this situation has been guided by one of Bitcoin’s core principles: self-sovereignty. In essence, self-sovereignty means taking full ownership of your participation in the network, holding your own keys, and running your own node with the rules you choose. In the book I authored on Bitcoin and self-sovereign principles, I emphasised that running a node is more than a technical task; it’s an expression of personal agency and values. Now, faced with Bitcoin Core’s direction that I deeply disagree with, I’m putting that ethos into practice.

For the past four months, I have been running Bitcoin Knots instead of the standard Bitcoin Core software. Bitcoin Knots is a well-established alternative client (maintained by Luke Dashjr) that, in many ways, is identical to Core except for a few important differences, notably, Knots retains stricter limits on OP_RETURN data and gives the user full control over relay filters. In fact, Knots by default still caps OP_RETURN at 40 bytes (the old limit from years ago) and allows only one OP_RETURN output per transaction. It’s basically “Bitcoin Core, but with the spam filter intact.” By running Knots, my node will not relay or mine the kind of oversized data-storing transactions that Core v30 endorses. More importantly, it signals my support for a vision of Bitcoin that prioritises financial transactions over arbitrary data. Knots users (myself included) see ourselves as defending Bitcoin’s integrity from a controversial experiment. We are effectively saying, “Not on my node!” when it comes to turning Bitcoin into an uncensored data dump.

I’m far from alone in this choice. As mentioned, a substantial minority of node operators are switching to Knots or sticking with older Core versions. This grass roots movement is reminiscent of how users can enforce their preferences in Bitcoin – much like the User Activated Soft Fork (UASF) concept, node runners can ‘vote’ by choosing which software to run. If enough of us reject Core v30, it could create economic incentives for miners to think twice about stuffing blocks with junk that a portion of the network won’t relay or perhaps even accept. (To be clear, Knots today does accept blocks created under Core’s new rules – it’s not a hard fork. The divergence is in relay policy and default behaviour, not consensus rules. This is a fight being waged via network policy, not chain splits… at least not yet.)

Self-sovereignty also means accepting personal responsibility for what I support in the network. That extends beyond just the software I run. It also influences my choices as a customer and community member. In light of the OP_RETURN controversy, I have decided on a few concrete actions, which I’ll outline here:

Running a “clean” node: I’ve migrated all my nodes to Bitcoin Knots and will continue to do so for the foreseeable future. This ensures that I am not propagating or validating illicit data beyond the absolute minimum required by consensus. If a bloated transaction or block crosses my node, Knots’ policies will treat it with the maximum strictness allowed (dropping it from mempool if possible, and certainly not relaying such transactions to peers). This is my way of keeping my corner of the Bitcoin network as clean of illicit content as possible. It’s a personal stand: I do not want even the chance of illegal material passing through my machine.

Boycotting services that endorse Core v30: I am discontinuing my use of any exchanges, custodians, or Bitcoin companies that I know are upgrading to or support the Core v30 software without protest. For example, if a company like River Financial or a tech firm like Blockstream chooses to run Core v30 nodes (thus knowingly accepting the relay of unlimited content, illicit or otherwise), then I will not be doing business with them. Those organizations might trust their lawyers or regulators to sort out the fallout of hosting illicit data on their nodes – that’s their prerogative. But I cannot in good conscience support institutions that, in my view, are inviting a flood of abusive content onto the Bitcoin blockchain and risking its reputation. My money and support will go to those who keep Bitcoin robust and respectable.

Advocating for a “clean” Bitcoin (even if it means a fork): Looking ahead, I suspect that other major players in the Bitcoin ecosystem share my concern, even if they aren’t voicing it loudly yet. Think of large public companies holding Bitcoin in their treasuries, or firms planning Bitcoin ETFs. The last thing these institutions want is to be entangled with a network that could inadvertently facilitate the spread of illegal content. It’s not hard to imagine some of them drawing a line: if Bitcoin’s protocol won’t address this problem, they might resort to extraordinary measures. This could include supporting a hard fork to create a “clean” version of Bitcoin that excises or filters out illicit material. BlackRock, for instance, is on the cusp of launching a spot Bitcoin ETF. In BlackRock’s own filings, they note that in the event of a fork, they have full discretion to decide which chain to consider the “real” Bitcoin for their fund.That means if a new fork gained momentum – say, a Bitcoin variant with strict protocol rules against arbitrary data – BlackRock could opt to adopt it for their ETF (or conversely, to abandon a chain that becomes too toxic). While this scenario sounds extreme, it’s entirely within the realm of possibility. The very fact that we’re discussing child pornography on the blockchain may prompt powerful stakeholders to assert control to protect their investments. I’m not actively calling for an immediate fork, that’s a complex, last-resort path, but I do believe that if Bitcoin Core’s path leads to legal quagmires, the market will find a way to course-correct, even if it means a chain split. My hope is that by raising awareness now, we can avert such drastic outcomes. But make no mistake: Bitcoin’s future must not include being a playground for criminal content, and I’ll support any serious effort to ensure that.

Bitcoin’s Future: Balancing Freedom and Responsibility

The controversy over OP_RETURN and illicit content forces an uncomfortable but necessary conversation about the future we want for Bitcoin. On one side is the ideal of total neutrality, Bitcoin as an unfilterable, permissionless ledger where “code is law” and even questionable data is just data. On the other side is the recognition that Bitcoin does not exist in a vacuum: if we undermine its primary use case as money or subject its participants to legal peril, we could kill the proverbial goose that lays the golden eggs. Finding the right balance is tricky. We cherish Bitcoin’s censorship-resistance precisely because it protects financial freedom and speech. Yet, does rejecting any filtering, even of grotesquely abusive content, truly serve the cause of freedom? Or does it hand enemies of Bitcoin the very weapon they need to attack it? These are challenging questions, and reasonable people in the community answer them differently.

For me, the answer comes back to self-sovereignty and consent. I did not sign up to store illicit images or arbitrary gigabytes of data on my node, that’s not the social contract under which I joined Bitcoin. My consent as a node operator matters. True decentralisation means we, the users get to collectively decide what the blockchain is for, by either running or not running certain code. It’s heartening to see that even Core developers acknowledge this in principle: “If Bitcoin Core’s contributors ever abandon [Bitcoin’s core] values… the community will switch to another node implementation that does it better,” wrote Gloria Zhao amidst the debate. I’d argue that forcing nodes to relay and store unlimited junk (with potentially ghastly contents) is a departure from the values that brought many of us to Bitcoin. And indeed, we’re seeing the community vote with its feet, or rather with its node software.

Moving forward, I believe Bitcoin will be stress-tested on this front. The coming months and years will reveal whether the network can accommodate new use-cases (like data inscriptions) without losing its soul – or whether a correction is needed. Perhaps Bitcoin Core’s gambit will pay off: maybe the “spam” will remain manageable, new pruning techniques will mitigate the bloat, and no criminal will attempt to abuse the blockchain’s openness. In that best case, my concerns would be eased (and I’d gladly acknowledge an overabundance of caution on my part). But if the worst case materialises, if obscene data starts showing up in blocks, if typical users find the chain clogged with non-financial data, if governments use this as a cudgel – then the community must be ready to respond decisively. Hard forks have happened before in Bitcoin’s history when values were at stake (recall the split that created Bitcoin Cash in 2017 over a blocksize dispute). A fork to preserve Bitcoin’s legal cleanliness and focused mission might become not just acceptable but essential to “future-proof” the network. And unlike a protocol tweak coming from a small group, a community or institution-driven fork would reflect a broad consensus that Bitcoin as it was is worth defending. BlackRock and other institutional players entering the space could ironically become allies in keeping Bitcoin safe for mainstream use – they will not tolerate holding an asset tainted by crime, so they have every incentive to back a solution, even if it’s a controversial one.

I didn’t need medication, I needed sovereignty.

For years I felt drained, distracted, and disconnected. I thought I was the problem. Turns out, it was the fiat system shaping my biology, attention, and habits. Bitcoin wasn’t just a financial shift, it rewired my incentives and my health. When you lower time preference, everything changes:

• Real food over fiat calories

• Sunlight over screens

• Strength over stress

• Creation over consumption

You’re not broken. The system is. And the fix isn’t another pill, it’s reclaiming your time, health, and money.

naddr1qv…ft0t

I once believed I was broken. Tired, distracted, restless. But the truth was harsher: I wasn’t broken, the system was.

Fiat incentives had trained me to live at a frantic pace, to consume instead of create, to chase dopamine over discipline. My calendar was full, but my life felt empty. Like many, I was medicating with convenience, processed food, endless scrolling, late nights under fluorescent light, thinking this was “normal.”

Then came the orange pill.

Bitcoin didn’t just change my portfolio. It changed my biology, my psychology, my very sense of time. Where fiat demanded instant gratification, Bitcoin rewarded patience. Where fiat created noise, Bitcoin restored signal. It was more than code; it was medicine.

Healing distorted incentives

Fiat medicine thrives on dependency. As I wrote in Brick by Brick:

“There’s no profit in a healthy person. And none in a dead one. The sweet spot is chronic dependency.”

We see it everywhere. Antidepressants handed out like candy. Supermarket aisles stacked with subsidized seed oils and sugar. Healthcare reduced to sickcare subscriptions.

In this environment, health isn’t the goal, compliance is. You are nudged, medicated, distracted, and kept just well enough to remain a customer.

Bitcoin flips that script. By lowering time preference, it rewards choices that compound health: eating real food, lifting heavy things, walking barefoot in the morning sun. The same mindset shift that helps you save in sats also helps you sleep deeper, think clearer, and eat with intention.

From Fiat Fog to Clarity

I remember deleting my social media apps, grounding barefoot at sunrise, and feeling the fog begin to lift. For the first time in years, I wasn’t drowning in notifications and stress. I was breathing again.

Bitcoin had rewired my incentives. It nudged me toward saving instead of speculating, nourishing instead of numbing, building instead of burning out.

As I put it in the book:

“Bitcoin restores signal. Fiat creates noise.”

That wasn’t just about economics. It was about my brain chemistry, my daily habits, and my mental health.

Bitcoin as Renaissance

This is why I call Bitcoin a renaissance, not just a revolution. It is more than a monetary upgrade, it’s a cultural reset.

Fiat culture tells us to chase shortcuts, hacks, and hype. Bitcoin culture invites us back to effort, patience, and proof-of-work.

I stopped hustling for fleeting highs and started cooking steak with my family. I swapped fast dopamine for slow strength. I began training my body with the same mindset I brought to my savings: small, consistent deposits that grow stronger over time.

You can’t build sovereignty on fiat food, fiat medicine, or fiat time. And you can’t fix your money without fixing your health.

Bitcoin heals both.

Let’s build your first brick

If you feel exhausted, inflamed, or distracted, you’re not broken. The system is. And the answer isn’t another pill. It’s sovereignty.

Start with money you can trust. Add food that nourishes instead of addicts. Reclaim attention from the feeds that steal it. Give yourself back to time itself.

That is the first brick. Once you lay it, the rest of the wall follows.

A Note on the Book

This article is drawn from my upcoming book, Brick by Brick: Building a Sovereign Life on Bitcoin. It weaves together money, health, data, attention, and energy into what I call the Sovereign Stack, a blueprint for opting out of fiat and reclaiming resilience.

Introduction: A New Controversy in Bitcoin’s Evolution

If you hold Bitcoin, if you call yourself a Bitcoiner, are you prepared to accept that the Bitcoin blockchain could be used to store illicit, even illegal content? This isn’t a hypothetical. Unless we act, by October 2025 the default Bitcoin Core software will make this the new reality. And if you don’t react now, your silence means acceptance.

Bitcoin is facing a pivotal controversy that cuts to the heart of its identity. The debate centres on a proposed change in Bitcoin’s core software that would remove longstanding limits on storing arbitrary data in transactions. On the surface, this change sounds technical – raising the OP_RETURN data limit from 80 bytes to nearly 4 megabytes, but its implications are profoundly human. Supporters hail it as an overdue embrace of censorship-resistance, while critics warn it could turn the blockchain into a host for illegal or abusive content. As a Bitcoiner who champions self-sovereignty and Bitcoin’s reputation as sound money, I find myself firmly in the latter camp. This article, written from my personal perspective and drawing on my book’s focus (Brick by Brick - <https://twentyone.life/brick-by-brick>) on self-sovereignty, explores why I’m taking a stand by running alternative software and even boycotting certain services, all in the name of a “clean” future for Bitcoin.

Background: Bitcoin Core v30 and the OP_RETURN Debate

At issue is a change slated for the upcoming Bitcoin Core version 30 (expected October 2025). Bitcoin Core is the dominant software for running nodes (over 75% of nodes run so its defaults largely define network behaviour. The core developers have decided to unshackle the OP_RETURN field, which historically allowed embedding only a tiny piece of data (≤83 bytes) in a transaction. This limit acted as a de facto “spam filter”, discouraging users from turning Bitcoin’s ledger into a generic data storage system.

Under Core v30, that filter is being removed entirely: users will be able to attach much larger data payloads, up to the size of a full block (~4MB), in a single transaction output. Moreover, Bitcoin Core will eliminate the configuration options (data carrier settings) that previously let node operators refuse relaying big OP_RETURN transactions. In short, the new default policy is “anything goes” for data, and individual node runners won’t easily opt out. While v30 still offers command-line tweaks to impose custom limits, those are now deprecated warnings likely to be removed later.

Why make this change? Proponents argue it’s a pragmatic response to reality. The 80-byte cap, they say, has been routinely bypassed by creative users who already insert larger data through other means – for example, using Taproot witness data or fake outputs (as seen in the 2023 Ordinals/“inscriptions” craze that let people embed images and art on Bitcoin). These workarounds are actually worse for the network: since the data is hidden in spendable outputs or witness scripts, it can bloat the UTXO set (the list of unspent coins) and increase validation costs for all nodes. By contrast, OP_RETURN outputs are provably unspendable and easily prunable. In the eyes of Core developers, it’s better to let people put data in OP_RETURN (where it doesn’t harm UTXO or decentralisation) than to have them continue abusing more harmful trick. Removing the cap “yields at least two tangible benefits: a cleaner UTXO set and more consistent default behaviour,” explained developer Greg Sanders. The change also aligns with Bitcoin’s values of neutrality, if a transaction is valid and pays the fee, who are nodes to censor it? Core maintainers like Gloria Zhao argue that trying to filter transactions at the node level is futile and against the principle of censorship-resistance.

On the other side, critics are alarmed. They counter that dropping these limits will open the floodgates to arbitrary data, fundamentally altering Bitcoin’s purpose. The blockchain could become a bloated “immutable database” of random content, potentially crowding out financial transactions with higher fees and diluting Bitcoin’s use as peer-to-peer money. What’s more, unbounded data storage invites spam, people could stuff blocks with endless memes, ads, or junk simply because they’re willing to pay. It’s a replay of the Blocksize War arguments, but instead of bigger blocks for payments, it’s bigger payloads for non-monetary data. The community is starkly divided: should Bitcoin evolve to support broader use cases (data, NFTs, digital artifacts), or should it resist becoming a free-for-all content repository and stick to financial utility? These positions are diametrically opposed, and the conflict has been heated – drawing comparisons to the acrimony of the 2017 blocksize debates.

Notably, longtime Bitcoin developer Luke Dashjr (author of an alternative client called Bitcoin Knots - https://x.com/LukeDashjr) has been one of the most vocal opponents besides Bitcoin Mechanic and Bitcoin University ( primal.net/kratter). He warns that the removal of what he bluntly calls “spam filters” is potentially harmful to the network and its users. Dashjr has publicly urged node operators to avoid upgrading to Core v30 or to switch to alternative software like Bitcoin Knots. In fact, many Bitcoiners have already acted on that advice. When the OP_RETURN plan was announced and fast-tracked earlier this year, there was a surge of users migrating their nodes from Core to Knots, by some estimates, over 15% of previously Core nodes switched to Bitcoin Knots in protest. The stage is set for a grass-roots pushback using Bitcoin’s own strength: decentralisation. True to the mantra of self-sovereignty, if you disagree with the default rules, you are free to run a node that reflects your values. I count myself among those taking that step.

Illicit Content on the Blockchain: The Serious Risks

Why am I, and others, so concerned about lifting the data limits? Because it’s not just “cute cat pictures” or art collections that could find their way onto Bitcoin’s ledger. The most dire possibility is the inclusion of illicit and abusive content in an immutable, globally replicated chain. This isn’t idle paranoia; it’s a genuine risk recognised by both sides of the debate. Even the advocates of OP_RETURN freedom acknowledge the “undesirable second-order effects” that could follow. Let’s spell it out: What if someone starts embedding child sexual abuse material (CSAM) or other illegal data in Bitcoin transactions? Once mined into a block, that content is there forever, every full node would unknowingly host it on their hard drive as part of the blockchain spreaded on tens of thousands nodes across the world. This scenario is a nightmare for obvious moral reasons, and it also poses a legal and reputational threat to anyone running a node or the Bitcoin network as a whole. Besides this, to spin up a new node will take longer and need higher technical hardware which leads to centralisation.

Unfortunately, the threat is not theoretical. It has already happened on a small scale. Researchers have found that forbidden content made its way onto Bitcoin as early as 2013, albeit in an obscure form. In 2018, a paper famously claimed that Bitcoin’s blockchain contained links to child pornography; at the time, critics dismissed it as sensationalism since only a few bytes of encoded data were involved and Core’s filters limited further abuse. But today we’re looking at a very different landscape. The data per block is increasing dramatically with the new policy. A concerned Bitcoiner known as “Bitcoin Mechanic” ( primal.net/p/nprofile1qqs8fl79rnpsz5x00xmvkvtd8g2u7ve2k2dr3lkfadyy4v24r4k3s4sh8dmel) recently warned that removing the filter “will draw unforeseen consequences,” meaning content like child pornography can appear on the Bitcoin blockchain” once v30 goes live. His point is straightforward: if you give bad actors the ability to inject large payloads, someone will inevitably push the worst kind of content into the system. And perversely, there’s a twisted incentive for them to do so: “Getting other people to store it for you is vastly preferable to storing it yourself,” Mechanic notes, what better way for criminals to disseminate vile material than piggyback on tens of thousands of innocent Bitcoin nodes?

Core developers have responded that these fears may be overblown. They often cite examples of other blockchains (for instance, Monero or Ethereum) that don’t have such data limits yet haven’t become overrun with illegal content. They stress that Bitcoin’s permissionless nature means anything could be written to it, but that doesn’t mean an epidemic of criminal data is imminent. Perhaps, but I would counter that Bitcoin’s global prominence and immutable design make it a uniquely attractive target for someone trying to cause chaos or discredit the system. It only takes one high-profile incident of truly heinous content on Bitcoin to unleash a regulatory crackdown. Remember, Bitcoin’s censorship-resistance cuts both ways: it empowers individuals, but it also neutralises traditional controls, which is exactly why governments get antsy when crimes enter the mix.

The legal implications of this are untested and scary. If a Bitcoin block contains illegal pornography or violent propaganda, could authorities argue that every node operator is technically in possession of contraband data? Some in the community worry that, yes, this could give governments a “perfect excuse to outlaw Bitcoin or make running a node illegal”. Even if that outcome is unlikely in jurisdictions that understand how Bitcoin works, the mere perception that Bitcoin is hosting criminal content would be a PR disaster. It would hand ammunition to anti-crypto politicians and could make regulators slam the brakes on adoption. As a Bitcoiner who wants to see this technology thrive, I find that risk unacceptable. Bitcoin’s social contract might be robust against internal dissent, but it’s not immune to external legal attack. Preserving Bitcoin’s integrity means ensuring it doesn’t become synonymous with “dark web file storage” in the public eye.

Embracing Self-Sovereignty: Why I Run Bitcoin Knots

My response to this situation has been guided by one of Bitcoin’s core principles: self-sovereignty. In essence, self-sovereignty means taking full ownership of your participation in the network, holding your own keys, and running your own node with the rules you choose. In the book I authored on Bitcoin and self-sovereign principles, I emphasised that running a node is more than a technical task; it’s an expression of personal agency and values. Now, faced with Bitcoin Core’s direction that I deeply disagree with, I’m putting that ethos into practice.

For the past four months, I have been running Bitcoin Knots instead of the standard Bitcoin Core software. Bitcoin Knots is a well-established alternative client (maintained by Luke Dashjr) that, in many ways, is identical to Core except for a few important differences, notably, Knots retains stricter limits on OP_RETURN data and gives the user full control over relay filters. In fact, Knots by default still caps OP_RETURN at 40 bytes (the old limit from years ago) and allows only one OP_RETURN output per transaction. It’s basically “Bitcoin Core, but with the spam filter intact.” By running Knots, my node will not relay or mine the kind of oversized data-storing transactions that Core v30 endorses. More importantly, it signals my support for a vision of Bitcoin that prioritises financial transactions over arbitrary data. Knots users (myself included) see ourselves as defending Bitcoin’s integrity from a controversial experiment. We are effectively saying, “Not on my node!” when it comes to turning Bitcoin into an uncensored data dump.

I’m far from alone in this choice. As mentioned, a substantial minority of node operators are switching to Knots or sticking with older Core versions. This grass roots movement is reminiscent of how users can enforce their preferences in Bitcoin – much like the User Activated Soft Fork (UASF) concept, node runners can ‘vote’ by choosing which software to run. If enough of us reject Core v30, it could create economic incentives for miners to think twice about stuffing blocks with junk that a portion of the network won’t relay or perhaps even accept. (To be clear, Knots today does accept blocks created under Core’s new rules – it’s not a hard fork. The divergence is in relay policy and default behaviour, not consensus rules. This is a fight being waged via network policy, not chain splits… at least not yet.)

Self-sovereignty also means accepting personal responsibility for what I support in the network. That extends beyond just the software I run. It also influences my choices as a customer and community member. In light of the OP_RETURN controversy, I have decided on a few concrete actions, which I’ll outline here:

Running a “clean” node: I’ve migrated all my nodes to Bitcoin Knots and will continue to do so for the foreseeable future. This ensures that I am not propagating or validating illicit data beyond the absolute minimum required by consensus. If a bloated transaction or block crosses my node, Knots’ policies will treat it with the maximum strictness allowed (dropping it from mempool if possible, and certainly not relaying such transactions to peers). This is my way of keeping my corner of the Bitcoin network as clean of illicit content as possible. It’s a personal stand: I do not want even the chance of illegal material passing through my machine.

Boycotting services that endorse Core v30: I am discontinuing my use of any exchanges, custodians, or Bitcoin companies that I know are upgrading to or support the Core v30 software without protest. For example, if a company like River Financial or a tech firm like Blockstream chooses to run Core v30 nodes (thus knowingly accepting the relay of unlimited content, illicit or otherwise), then I will not be doing business with them. Those organizations might trust their lawyers or regulators to sort out the fallout of hosting illicit data on their nodes – that’s their prerogative. But I cannot in good conscience support institutions that, in my view, are inviting a flood of abusive content onto the Bitcoin blockchain and risking its reputation. My money and support will go to those who keep Bitcoin robust and respectable.

Advocating for a “clean” Bitcoin (even if it means a fork): Looking ahead, I suspect that other major players in the Bitcoin ecosystem share my concern, even if they aren’t voicing it loudly yet. Think of large public companies holding Bitcoin in their treasuries, or firms planning Bitcoin ETFs. The last thing these institutions want is to be entangled with a network that could inadvertently facilitate the spread of illegal content. It’s not hard to imagine some of them drawing a line: if Bitcoin’s protocol won’t address this problem, they might resort to extraordinary measures. This could include supporting a hard fork to create a “clean” version of Bitcoin that excises or filters out illicit material. BlackRock, for instance, is on the cusp of launching a spot Bitcoin ETF. In BlackRock’s own filings, they note that in the event of a fork, they have full discretion to decide which chain to consider the “real” Bitcoin for their fund.That means if a new fork gained momentum – say, a Bitcoin variant with strict protocol rules against arbitrary data – BlackRock could opt to adopt it for their ETF (or conversely, to abandon a chain that becomes too toxic). While this scenario sounds extreme, it’s entirely within the realm of possibility. The very fact that we’re discussing child pornography on the blockchain may prompt powerful stakeholders to assert control to protect their investments. I’m not actively calling for an immediate fork, that’s a complex, last-resort path, but I do believe that if Bitcoin Core’s path leads to legal quagmires, the market will find a way to course-correct, even if it means a chain split. My hope is that by raising awareness now, we can avert such drastic outcomes. But make no mistake: Bitcoin’s future must not include being a playground for criminal content, and I’ll support any serious effort to ensure that.

Bitcoin’s Future: Balancing Freedom and Responsibility

The controversy over OP_RETURN and illicit content forces an uncomfortable but necessary conversation about the future we want for Bitcoin. On one side is the ideal of total neutrality, Bitcoin as an unfilterable, permissionless ledger where “code is law” and even questionable data is just data. On the other side is the recognition that Bitcoin does not exist in a vacuum: if we undermine its primary use case as money or subject its participants to legal peril, we could kill the proverbial goose that lays the golden eggs. Finding the right balance is tricky. We cherish Bitcoin’s censorship-resistance precisely because it protects financial freedom and speech. Yet, does rejecting any filtering, even of grotesquely abusive content, truly serve the cause of freedom? Or does it hand enemies of Bitcoin the very weapon they need to attack it? These are challenging questions, and reasonable people in the community answer them differently.

For me, the answer comes back to self-sovereignty and consent. I did not sign up to store illicit images or arbitrary gigabytes of data on my node, that’s not the social contract under which I joined Bitcoin. My consent as a node operator matters. True decentralisation means we, the users get to collectively decide what the blockchain is for, by either running or not running certain code. It’s heartening to see that even Core developers acknowledge this in principle: “If Bitcoin Core’s contributors ever abandon [Bitcoin’s core] values… the community will switch to another node implementation that does it better,” wrote Gloria Zhao amidst the debate. I’d argue that forcing nodes to relay and store unlimited junk (with potentially ghastly contents) is a departure from the values that brought many of us to Bitcoin. And indeed, we’re seeing the community vote with its feet, or rather with its node software.

Moving forward, I believe Bitcoin will be stress-tested on this front. The coming months and years will reveal whether the network can accommodate new use-cases (like data inscriptions) without losing its soul – or whether a correction is needed. Perhaps Bitcoin Core’s gambit will pay off: maybe the “spam” will remain manageable, new pruning techniques will mitigate the bloat, and no criminal will attempt to abuse the blockchain’s openness. In that best case, my concerns would be eased (and I’d gladly acknowledge an overabundance of caution on my part). But if the worst case materialises, if obscene data starts showing up in blocks, if typical users find the chain clogged with non-financial data, if governments use this as a cudgel – then the community must be ready to respond decisively. Hard forks have happened before in Bitcoin’s history when values were at stake (recall the split that created Bitcoin Cash in 2017 over a blocksize dispute). A fork to preserve Bitcoin’s legal cleanliness and focused mission might become not just acceptable but essential to “future-proof” the network. And unlike a protocol tweak coming from a small group, a community or institution-driven fork would reflect a broad consensus that Bitcoin as it was is worth defending. BlackRock and other institutional players entering the space could ironically become allies in keeping Bitcoin safe for mainstream use – they will not tolerate holding an asset tainted by crime, so they have every incentive to back a solution, even if it’s a controversial one.

Conclusion: Upholding Bitcoin’s Integrity

In closing, my stance can be distilled to this: Bitcoin’s strength lies in our ability to choose and enforce the rules that best uphold the network’s purpose and integrity. As a self-sovereign participant, I choose to reject the notion that Bitcoin must accept everything in the name of “freedom,” especially when that freedom can be cynically exploited to Bitcoin’s detriment. Instead, I align with the principle that some judicious constraints, whether at the software policy level or the community social level, are necessary to keep Bitcoin healthy, useful, and legally accessible to all. This is a nuanced position, and it may be polarising. Some will accuse me of advocating “censorship” or betraying Bitcoin’s neutrality. I respect the purist viewpoint, but I humbly disagree in this case. Refusing to store illegal content is not tyranny; it’s common sense. We can defend freedom of transaction without turning Bitcoin into a sanctuary for the worst humanity has to offer.

In my book on self-sovereignty, I wrote that with great power comes great responsibility, running a Bitcoin node is indeed powerful, and it’s up to each of us to act responsibly with that power. Today, responsibility calls for vigilance about what changes we adopt. I am communicating these thoughts as part of my ongoing effort to ensure Bitcoin remains future-proof. “Future-proofing” Bitcoin doesn’t just mean scaling it or boosting hash rate; it also means safeguarding its social acceptance and moral foundation. By voicing dissent, by switching implementations, by potentially forking if needed, we the users are stress-testing Bitcoin’s resilience in exactly the way it was designed to be: from the bottom up.

Bitcoin’s story has always been about empowerment of the individual. This current saga, the Node Wars over OP_RETURN and content, is yet another chapter in that story. I, for one, am determined to see Bitcoin thrive as a tool of financial liberation, unsullied by association with illicit content. It may ruffle feathers now, but principled stances often do. As the saying goes, “Bitcoin is for enemies”, but that doesn’t mean we have to let enemies turn it against us. My hope is that through self-sovereign action and frank dialogue, we will navigate this challenge and emerge with a Bitcoin network that is both freer and more secure, a network that can confidently serve the world for decades to come, without any shadow of disgrace on its ledger.

The choice is in front of us. By October 2025, Bitcoin Core v30 will normalise the relaying of arbitrary, potentially illicit content across the network. If we do nothing, if we keep quiet, then we silently consent to this shift. As Bitcoiners, we must ask ourselves: do we want our blockchain remembered as the foundation of sound money, or as a storage ground for abuse?

I’ve made my decision, I run Bitcoin Knots, I reject services that endorse Core v30, and I will defend a “clean” Bitcoin that remains worthy of global trust. The question is: what kind of Bitcoin are you willing to stand behind?

The European Central Bank is pushing ahead with the digital euro. Politicians and officials describe it as efficient, modern, and inclusive. But behind the glossy language lies a project that could reshape not just money, but freedom itself. In my book Brick by Brick: Building a Sovereign Life on Bitcoin I explored what CBDCs mean for democracy, autonomy, and human dignity. Here is why the digital euro should concern every European citizen.

Central Bank Digital Currencies are promoted as the inevitable next step in the evolution of money. In the European Union, the digital euro is marketed as citizen-friendly, efficient, and inclusive. Yet behind this polished language lies a project of control rather than progress.

In Brick by Brick I wrote that CBDCs are money with strings, while Bitcoin is money with freedom. This contrast captures the core of the issue. A CBDC is not simply digital cash. It is programmable, meaning that conditions can be attached to how, when, and where money is spent. In the book I described it as a digital cage dressed up as convenience. Cash is freedom. Programmable money is prison with a user interface.

We have already seen glimpses of what financial deplatforming looks like. In 2022, during the Canadian trucker protests, bank accounts were frozen, donations seized, and ordinary citizens suddenly excluded from their financial lives. And this happened without the infrastructure of a CBDC. Imagine what it means when the central bank itself has direct control over every transaction, with the ability to switch off dissent not with riot police, but with a keystroke in your wallet.

The leadership of this project matters. The European Central Bank is run by officials who are not elected by the public. Its president, Christine Lagarde, was convicted in 2016 for negligence over a 400 million euro payout while serving as France’s finance minister. This is the person now shaping a currency that could govern the everyday transactions of hundreds of millions of Europeans. Should unelected technocrats, led by someone with such a record, be entrusted with such sweeping power?

Professor Richard Werner, one of the most insightful critics of central banking, has shown that central banks were never designed as neutral guardians of stability. Watch the video below, it the best invest for your time, it is simple eye-opening.

<<https://www.youtube.com/watch?v=StTKHskg5Tg>>

Many were created to finance wars without asking citizens to pay for them upfront. They are instruments of state power. Handing them the tools of total financial surveillance should concern anyone who values democracy and human dignity.

There is another layer of disruption that is rarely discussed. Under many designs, CBDCs allow citizens to hold accounts directly with the central bank. This bypasses commercial banks and raises the possibility that their traditional role as deposit takers could become redundant. Banking consultancies like McKinsey openly warn that a fully account-based CBDC could displace a significant share of deposits. Academics note that such a model forces the central bank into direct competition with commercial banks. In short, the banking system as we know it could shrink into a thin service layer while the central bank becomes everyone’s bank. Whether the banking industry fully recognises this existential risk is still unclear.

The European Central Bank outlines several features of the digital euro. On the surface, they sound beneficial. But for citizens, each feature carries implications that deserve scrutiny:

Digital cash backed by the ECB: balances become direct claims on the central bank, not on private banks. This centralises all trust in a single authority.

Universally accepted: works in all shops and online. Convenient, but also makes opting out difficult.

Free of charge for basic use: no fees at first glance, but hidden costs may emerge through other mechanisms like negative interest.

Offline capability: useful for resilience, but requires hardware trust and may introduce limits on usage.

Privacy within limits: promises of cash-like anonymity can be revoked for compliance, leaving citizens only conditionally private.

Guaranteed parity with the euro: stability in name, but value can be manipulated through features like expiration or conditional spending.

Not a crypto-asset: entirely centralised, without the neutrality of decentralized systems like Bitcoin.

Dual structure with intermediaries: banks may survive as front ends, but lose deposits and become service providers.

Individual holding limits: caps on wallet balances allow authorities to restrict how much of your wealth can sit in a CBDC.

Programmable features: the most powerful lever, enabling restrictions on where, when, and how money is used.

Taken together, these features could fundamentally reshape daily life. You may no longer need a commercial bank for everyday transactions, but you also may no longer be free to use money without oversight. Your spending, savings, and even your choices could be managed through central infrastructure. Commercial banks will fight to remain relevant, but in a system that sees them as optional, their survival is not guaranteed.

A possible future one CBDCs are taking over - Not just fiction take a look to China's social scoring.

The deeper question remains. Should we trade autonomy for convenience? Should we allow unelected technocrats, led by Christine Lagarde, to design programmable money with built-in surveillance? Should institutions created to fund wars without citizen consent now be upgraded into tools of total financial control?

A financial system where the central bank is your bank is not progress. It is control. Bitcoin, by contrast, is voluntary, neutral, and permissionless. It is money without strings. That difference is not technical. It is civilizational.

CBDCs are not just about modernization. They are about control. We stand at a turning point where money can either remain a tool of human freedom or become a mechanism of surveillance. In Brick by Brick I go deeper into these questions, connecting money, health, and sovereignty.

🔥 “The lie begins with money, but it does not end there. Fiat distorts our very existence.”

Introduction: A New Controversy in Bitcoin’s Evolution

If you hold Bitcoin, if you call yourself a Bitcoiner, are you prepared to accept that the Bitcoin blockchain could be used to store illicit, even illegal content? This isn’t a hypothetical. Unless we act, by October 2025 the default Bitcoin Core software will make this the new reality. And if you don’t react now, your silence means acceptance.

Bitcoin is facing a pivotal controversy that cuts to the heart of its identity. The debate centres on a proposed change in Bitcoin’s core software that would remove longstanding limits on storing arbitrary data in transactions. On the surface, this change sounds technical – raising the OP_RETURN data limit from 80 bytes to nearly 4 megabytes, but its implications are profoundly human. Supporters hail it as an overdue embrace of censorship-resistance, while critics warn it could turn the blockchain into a host for illegal or abusive content. As a Bitcoiner who champions self-sovereignty and Bitcoin’s reputation as sound money, I find myself firmly in the latter camp. This article, written from my personal perspective and drawing on my book’s focus (Brick by Brick - <https://twentyone.life/brick-by-brick>) on self-sovereignty, explores why I’m taking a stand by running alternative software and even boycotting certain services, all in the name of a “clean” future for Bitcoin.

Background: Bitcoin Core v30 and the OP_RETURN Debate

At issue is a change slated for the upcoming Bitcoin Core version 30 (expected October 2025). Bitcoin Core is the dominant software for running nodes (over 75% of nodes run so its defaults largely define network behaviour. The core developers have decided to unshackle the OP_RETURN field, which historically allowed embedding only a tiny piece of data (≤83 bytes) in a transaction. This limit acted as a de facto “spam filter”, discouraging users from turning Bitcoin’s ledger into a generic data storage system.

Under Core v30, that filter is being removed entirely: users will be able to attach much larger data payloads, up to the size of a full block (~4MB), in a single transaction output. Moreover, Bitcoin Core will eliminate the configuration options (data carrier settings) that previously let node operators refuse relaying big OP_RETURN transactions. In short, the new default policy is “anything goes” for data, and individual node runners won’t easily opt out. While v30 still offers command-line tweaks to impose custom limits, those are now deprecated warnings likely to be removed later.

Why make this change? Proponents argue it’s a pragmatic response to reality. The 80-byte cap, they say, has been routinely bypassed by creative users who already insert larger data through other means – for example, using Taproot witness data or fake outputs (as seen in the 2023 Ordinals/“inscriptions” craze that let people embed images and art on Bitcoin). These workarounds are actually worse for the network: since the data is hidden in spendable outputs or witness scripts, it can bloat the UTXO set (the list of unspent coins) and increase validation costs for all nodes. By contrast, OP_RETURN outputs are provably unspendable and easily prunable. In the eyes of Core developers, it’s better to let people put data in OP_RETURN (where it doesn’t harm UTXO or decentralisation) than to have them continue abusing more harmful trick. Removing the cap “yields at least two tangible benefits: a cleaner UTXO set and more consistent default behaviour,” explained developer Greg Sanders. The change also aligns with Bitcoin’s values of neutrality, if a transaction is valid and pays the fee, who are nodes to censor it? Core maintainers like Gloria Zhao argue that trying to filter transactions at the node level is futile and against the principle of censorship-resistance.

On the other side, critics are alarmed. They counter that dropping these limits will open the floodgates to arbitrary data, fundamentally altering Bitcoin’s purpose. The blockchain could become a bloated “immutable database” of random content, potentially crowding out financial transactions with higher fees and diluting Bitcoin’s use as peer-to-peer money. What’s more, unbounded data storage invites spam, people could stuff blocks with endless memes, ads, or junk simply because they’re willing to pay. It’s a replay of the Blocksize War arguments, but instead of bigger blocks for payments, it’s bigger payloads for non-monetary data. The community is starkly divided: should Bitcoin evolve to support broader use cases (data, NFTs, digital artifacts), or should it resist becoming a free-for-all content repository and stick to financial utility? These positions are diametrically opposed, and the conflict has been heated – drawing comparisons to the acrimony of the 2017 blocksize debates.

Notably, longtime Bitcoin developer Luke Dashjr (author of an alternative client called Bitcoin Knots - https://x.com/LukeDashjr) has been one of the most vocal opponents besides Bitcoin Mechanic and Bitcoin University ( primal.net/kratter). He warns that the removal of what he bluntly calls “spam filters” is potentially harmful to the network and its users. Dashjr has publicly urged node operators to avoid upgrading to Core v30 or to switch to alternative software like Bitcoin Knots. In fact, many Bitcoiners have already acted on that advice. When the OP_RETURN plan was announced and fast-tracked earlier this year, there was a surge of users migrating their nodes from Core to Knots, by some estimates, over 15% of previously Core nodes switched to Bitcoin Knots in protest. The stage is set for a grass-roots pushback using Bitcoin’s own strength: decentralisation. True to the mantra of self-sovereignty, if you disagree with the default rules, you are free to run a node that reflects your values. I count myself among those taking that step.

Illicit Content on the Blockchain: The Serious Risks

Why am I, and others, so concerned about lifting the data limits? Because it’s not just “cute cat pictures” or art collections that could find their way onto Bitcoin’s ledger. The most dire possibility is the inclusion of illicit and abusive content in an immutable, globally replicated chain. This isn’t idle paranoia; it’s a genuine risk recognised by both sides of the debate. Even the advocates of OP_RETURN freedom acknowledge the “undesirable second-order effects” that could follow. Let’s spell it out: What if someone starts embedding child sexual abuse material (CSAM) or other illegal data in Bitcoin transactions? Once mined into a block, that content is there forever, every full node would unknowingly host it on their hard drive as part of the blockchain spreaded on tens of thousands nodes across the world. This scenario is a nightmare for obvious moral reasons, and it also poses a legal and reputational threat to anyone running a node or the Bitcoin network as a whole. Besides this, to spin up a new node will take longer and need higher technical hardware which leads to centralisation.

Unfortunately, the threat is not theoretical. It has already happened on a small scale. Researchers have found that forbidden content made its way onto Bitcoin as early as 2013, albeit in an obscure form. In 2018, a paper famously claimed that Bitcoin’s blockchain contained links to child pornography; at the time, critics dismissed it as sensationalism since only a few bytes of encoded data were involved and Core’s filters limited further abuse. But today we’re looking at a very different landscape. The data per block is increasing dramatically with the new policy. A concerned Bitcoiner known as “Bitcoin Mechanic” ( primal.net/p/nprofile1qqs8fl79rnpsz5x00xmvkvtd8g2u7ve2k2dr3lkfadyy4v24r4k3s4sh8dmel) recently warned that removing the filter “will draw unforeseen consequences,” meaning content like child pornography can appear on the Bitcoin blockchain” once v30 goes live. His point is straightforward: if you give bad actors the ability to inject large payloads, someone will inevitably push the worst kind of content into the system. And perversely, there’s a twisted incentive for them to do so: “Getting other people to store it for you is vastly preferable to storing it yourself,” Mechanic notes, what better way for criminals to disseminate vile material than piggyback on tens of thousands of innocent Bitcoin nodes?

Core developers have responded that these fears may be overblown. They often cite examples of other blockchains (for instance, Monero or Ethereum) that don’t have such data limits yet haven’t become overrun with illegal content. They stress that Bitcoin’s permissionless nature means anything could be written to it, but that doesn’t mean an epidemic of criminal data is imminent. Perhaps, but I would counter that Bitcoin’s global prominence and immutable design make it a uniquely attractive target for someone trying to cause chaos or discredit the system. It only takes one high-profile incident of truly heinous content on Bitcoin to unleash a regulatory crackdown. Remember, Bitcoin’s censorship-resistance cuts both ways: it empowers individuals, but it also neutralises traditional controls, which is exactly why governments get antsy when crimes enter the mix.

The legal implications of this are untested and scary. If a Bitcoin block contains illegal pornography or violent propaganda, could authorities argue that every node operator is technically in possession of contraband data? Some in the community worry that, yes, this could give governments a “perfect excuse to outlaw Bitcoin or make running a node illegal”. Even if that outcome is unlikely in jurisdictions that understand how Bitcoin works, the mere perception that Bitcoin is hosting criminal content would be a PR disaster. It would hand ammunition to anti-crypto politicians and could make regulators slam the brakes on adoption. As a Bitcoiner who wants to see this technology thrive, I find that risk unacceptable. Bitcoin’s social contract might be robust against internal dissent, but it’s not immune to external legal attack. Preserving Bitcoin’s integrity means ensuring it doesn’t become synonymous with “dark web file storage” in the public eye.

Embracing Self-Sovereignty: Why I Run Bitcoin Knots

My response to this situation has been guided by one of Bitcoin’s core principles: self-sovereignty. In essence, self-sovereignty means taking full ownership of your participation in the network, holding your own keys, and running your own node with the rules you choose. In the book I authored on Bitcoin and self-sovereign principles, I emphasised that running a node is more than a technical task; it’s an expression of personal agency and values. Now, faced with Bitcoin Core’s direction that I deeply disagree with, I’m putting that ethos into practice.

For the past four months, I have been running Bitcoin Knots instead of the standard Bitcoin Core software. Bitcoin Knots is a well-established alternative client (maintained by Luke Dashjr) that, in many ways, is identical to Core except for a few important differences, notably, Knots retains stricter limits on OP_RETURN data and gives the user full control over relay filters. In fact, Knots by default still caps OP_RETURN at 40 bytes (the old limit from years ago) and allows only one OP_RETURN output per transaction. It’s basically “Bitcoin Core, but with the spam filter intact.” By running Knots, my node will not relay or mine the kind of oversized data-storing transactions that Core v30 endorses. More importantly, it signals my support for a vision of Bitcoin that prioritises financial transactions over arbitrary data. Knots users (myself included) see ourselves as defending Bitcoin’s integrity from a controversial experiment. We are effectively saying, “Not on my node!” when it comes to turning Bitcoin into an uncensored data dump.

I’m far from alone in this choice. As mentioned, a substantial minority of node operators are switching to Knots or sticking with older Core versions. This grass roots movement is reminiscent of how users can enforce their preferences in Bitcoin – much like the User Activated Soft Fork (UASF) concept, node runners can ‘vote’ by choosing which software to run. If enough of us reject Core v30, it could create economic incentives for miners to think twice about stuffing blocks with junk that a portion of the network won’t relay or perhaps even accept. (To be clear, Knots today does accept blocks created under Core’s new rules – it’s not a hard fork. The divergence is in relay policy and default behaviour, not consensus rules. This is a fight being waged via network policy, not chain splits… at least not yet.)

Self-sovereignty also means accepting personal responsibility for what I support in the network. That extends beyond just the software I run. It also influences my choices as a customer and community member. In light of the OP_RETURN controversy, I have decided on a few concrete actions, which I’ll outline here:

Running a “clean” node: I’ve migrated all my nodes to Bitcoin Knots and will continue to do so for the foreseeable future. This ensures that I am not propagating or validating illicit data beyond the absolute minimum required by consensus. If a bloated transaction or block crosses my node, Knots’ policies will treat it with the maximum strictness allowed (dropping it from mempool if possible, and certainly not relaying such transactions to peers). This is my way of keeping my corner of the Bitcoin network as clean of illicit content as possible. It’s a personal stand: I do not want even the chance of illegal material passing through my machine.

Boycotting services that endorse Core v30: I am discontinuing my use of any exchanges, custodians, or Bitcoin companies that I know are upgrading to or support the Core v30 software without protest. For example, if a company like River Financial or a tech firm like Blockstream chooses to run Core v30 nodes (thus knowingly accepting the relay of unlimited content, illicit or otherwise), then I will not be doing business with them. Those organizations might trust their lawyers or regulators to sort out the fallout of hosting illicit data on their nodes – that’s their prerogative. But I cannot in good conscience support institutions that, in my view, are inviting a flood of abusive content onto the Bitcoin blockchain and risking its reputation. My money and support will go to those who keep Bitcoin robust and respectable.

Advocating for a “clean” Bitcoin (even if it means a fork): Looking ahead, I suspect that other major players in the Bitcoin ecosystem share my concern, even if they aren’t voicing it loudly yet. Think of large public companies holding Bitcoin in their treasuries, or firms planning Bitcoin ETFs. The last thing these institutions want is to be entangled with a network that could inadvertently facilitate the spread of illegal content. It’s not hard to imagine some of them drawing a line: if Bitcoin’s protocol won’t address this problem, they might resort to extraordinary measures. This could include supporting a hard fork to create a “clean” version of Bitcoin that excises or filters out illicit material. BlackRock, for instance, is on the cusp of launching a spot Bitcoin ETF. In BlackRock’s own filings, they note that in the event of a fork, they have full discretion to decide which chain to consider the “real” Bitcoin for their fund.That means if a new fork gained momentum – say, a Bitcoin variant with strict protocol rules against arbitrary data – BlackRock could opt to adopt it for their ETF (or conversely, to abandon a chain that becomes too toxic). While this scenario sounds extreme, it’s entirely within the realm of possibility. The very fact that we’re discussing child pornography on the blockchain may prompt powerful stakeholders to assert control to protect their investments. I’m not actively calling for an immediate fork, that’s a complex, last-resort path, but I do believe that if Bitcoin Core’s path leads to legal quagmires, the market will find a way to course-correct, even if it means a chain split. My hope is that by raising awareness now, we can avert such drastic outcomes. But make no mistake: Bitcoin’s future must not include being a playground for criminal content, and I’ll support any serious effort to ensure that.

Bitcoin’s Future: Balancing Freedom and Responsibility

The controversy over OP_RETURN and illicit content forces an uncomfortable but necessary conversation about the future we want for Bitcoin. On one side is the ideal of total neutrality, Bitcoin as an unfilterable, permissionless ledger where “code is law” and even questionable data is just data. On the other side is the recognition that Bitcoin does not exist in a vacuum: if we undermine its primary use case as money or subject its participants to legal peril, we could kill the proverbial goose that lays the golden eggs. Finding the right balance is tricky. We cherish Bitcoin’s censorship-resistance precisely because it protects financial freedom and speech. Yet, does rejecting any filtering, even of grotesquely abusive content, truly serve the cause of freedom? Or does it hand enemies of Bitcoin the very weapon they need to attack it? These are challenging questions, and reasonable people in the community answer them differently.

For me, the answer comes back to self-sovereignty and consent. I did not sign up to store illicit images or arbitrary gigabytes of data on my node, that’s not the social contract under which I joined Bitcoin. My consent as a node operator matters. True decentralisation means we, the users get to collectively decide what the blockchain is for, by either running or not running certain code. It’s heartening to see that even Core developers acknowledge this in principle: “If Bitcoin Core’s contributors ever abandon [Bitcoin’s core] values… the community will switch to another node implementation that does it better,” wrote Gloria Zhao amidst the debate. I’d argue that forcing nodes to relay and store unlimited junk (with potentially ghastly contents) is a departure from the values that brought many of us to Bitcoin. And indeed, we’re seeing the community vote with its feet, or rather with its node software.

Moving forward, I believe Bitcoin will be stress-tested on this front. The coming months and years will reveal whether the network can accommodate new use-cases (like data inscriptions) without losing its soul – or whether a correction is needed. Perhaps Bitcoin Core’s gambit will pay off: maybe the “spam” will remain manageable, new pruning techniques will mitigate the bloat, and no criminal will attempt to abuse the blockchain’s openness. In that best case, my concerns would be eased (and I’d gladly acknowledge an overabundance of caution on my part). But if the worst case materialises, if obscene data starts showing up in blocks, if typical users find the chain clogged with non-financial data, if governments use this as a cudgel – then the community must be ready to respond decisively. Hard forks have happened before in Bitcoin’s history when values were at stake (recall the split that created Bitcoin Cash in 2017 over a blocksize dispute). A fork to preserve Bitcoin’s legal cleanliness and focused mission might become not just acceptable but essential to “future-proof” the network. And unlike a protocol tweak coming from a small group, a community or institution-driven fork would reflect a broad consensus that Bitcoin as it was is worth defending. BlackRock and other institutional players entering the space could ironically become allies in keeping Bitcoin safe for mainstream use – they will not tolerate holding an asset tainted by crime, so they have every incentive to back a solution, even if it’s a controversial one.

Conclusion: Upholding Bitcoin’s Integrity

In closing, my stance can be distilled to this: Bitcoin’s strength lies in our ability to choose and enforce the rules that best uphold the network’s purpose and integrity. As a self-sovereign participant, I choose to reject the notion that Bitcoin must accept everything in the name of “freedom,” especially when that freedom can be cynically exploited to Bitcoin’s detriment. Instead, I align with the principle that some judicious constraints, whether at the software policy level or the community social level, are necessary to keep Bitcoin healthy, useful, and legally accessible to all. This is a nuanced position, and it may be polarising. Some will accuse me of advocating “censorship” or betraying Bitcoin’s neutrality. I respect the purist viewpoint, but I humbly disagree in this case. Refusing to store illegal content is not tyranny; it’s common sense. We can defend freedom of transaction without turning Bitcoin into a sanctuary for the worst humanity has to offer.

In my book on self-sovereignty, I wrote that with great power comes great responsibility, running a Bitcoin node is indeed powerful, and it’s up to each of us to act responsibly with that power. Today, responsibility calls for vigilance about what changes we adopt. I am communicating these thoughts as part of my ongoing effort to ensure Bitcoin remains future-proof. “Future-proofing” Bitcoin doesn’t just mean scaling it or boosting hash rate; it also means safeguarding its social acceptance and moral foundation. By voicing dissent, by switching implementations, by potentially forking if needed, we the users are stress-testing Bitcoin’s resilience in exactly the way it was designed to be: from the bottom up.

Bitcoin’s story has always been about empowerment of the individual. This current saga, the Node Wars over OP_RETURN and content, is yet another chapter in that story. I, for one, am determined to see Bitcoin thrive as a tool of financial liberation, unsullied by association with illicit content. It may ruffle feathers now, but principled stances often do. As the saying goes, “Bitcoin is for enemies”, but that doesn’t mean we have to let enemies turn it against us. My hope is that through self-sovereign action and frank dialogue, we will navigate this challenge and emerge with a Bitcoin network that is both freer and more secure, a network that can confidently serve the world for decades to come, without any shadow of disgrace on its ledger.

The choice is in front of us. By October 2025, Bitcoin Core v30 will normalise the relaying of arbitrary, potentially illicit content across the network. If we do nothing, if we keep quiet, then we silently consent to this shift. As Bitcoiners, we must ask ourselves: do we want our blockchain remembered as the foundation of sound money, or as a storage ground for abuse?

I’ve made my decision, I run Bitcoin Knots, I reject services that endorse Core v30, and I will defend a “clean” Bitcoin that remains worthy of global trust. The question is: what kind of Bitcoin are you willing to stand behind?
