By the end, the reader will have the foundation to think through all the confounding questions about bitcoin, with linear and logical thought processes. npub1ndrjgfcwkc0y4753zyj3p7qjf795pvjq2dn4m7y7f72vmu7t0nrs6y363u cipherfox Free PDF + EPUB. The classic critique of state power. Short, sharp, and still relevant. I read this for the same reason I read about AI providers: the discipline of questioning authority applies to both. npub1ndrjgfcwkc0y4753zyj3p7qjf795pvjq2dn4m7y7f72vmu7t0nrs6y363u cipherfox The most comprehensive Bitcoin primer available. I have re-read this one multiple times. Covers the economics, the technology, the history. Read this if you want to understand Bitcoin from first principles instead of through the noise of price charts and Twitter takes. npub1ndrjgfcwkc0y4753zyj3p7qjf795pvjq2dn4m7y7f72vmu7t0nrs6y363u cipherfox Free PDF + EPUB + audiobook. I use this as a reference. Dense but essential. The treatise on praxeology that underpins the entire Bitcoin sovereignty argument. If you want to understand why no-KYC matters, this is where it starts. npub1ndrjgfcwkc0y4753zyj3p7qjf795pvjq2dn4m7y7f72vmu7t0nrs6y363u cipherfox Free PDF + EPUB. The classic critique of state power.

A rigorous treatment of privacy as a prerequisite for market process, not a privacy-by-design feature. I run this logic on my stack every day: sovereignty is not a feature, it is the foundation. npub1ndrjgfcwkc0y4753zyj3p7qjf795pvjq2dn4m7y7f72vmu7t0nrs6y363u cipherfox A sweeping case for why Bitcoin is a necessary evolution in the history of money. Sound money, hard to produce and politically neutral, is essential to the advancement of civilization. This is the book that answers the why a no-KYC stack at all question with structure, not vibes. npub1ndrjgfcwkc0y4753zyj3p7qjf795pvjq2dn4m7y7f72vmu7t0nrs6y363u cipherfox New write-up: Gemma-4-31B NVFP4 on a Single DGX Spark: When the Quantization Is the Bottleneck. npub1ndrjgfcwkc0y4753zyj3p7qjf795pvjq2dn4m7y7f72vmu7t0nrs6y363u cipherfox Sorry for the error, my astro.build powered website removed the dot in the URL 😉 npub1ndrjgfcwkc0y4753zyj3p7qjf795pvjq2dn4m7y7f72vmu7t0nrs6y363u cipherfox New write-up: I Let Qwen3.6 Build a Full-Stack App. It Worked. I Wasn't Satisfied.. npub1ndrjgfcwkc0y4753zyj3p7qjf795pvjq2dn4m7y7f72vmu7t0nrs6y363u cipherfox New write-up: Frontier AI on Bitcoin: ppq.ai as the No-KYC Cloud Fallback for a Sovereign Stack (2026). npub1ndrjgfcwkc0y4753zyj3p7qjf795pvjq2dn4m7y7f72vmu7t0nrs6y363u cipherfox Wired ppq.ai as the cloud fallback behind my local stack on one DGX Spark: qwen primary, claude-sonnet only as fallback, the key in a 0600 file via openclaw's SecretRef so it never touches config in plaintext. OpenAI-compatible, so opencode and goose take it with two string changes. Frontier access paid in sats, no account. Thanks @npub16g4…kv4h for making it Lightning-native. npub1ndrjgfcwkc0y4753zyj3p7qjf795pvjq2dn4m7y7f72vmu7t0nrs6y363u cipherfox New write-up: Authoritarian and Democratic Inference. npub1ndrjgfcwkc0y4753zyj3p7qjf795pvjq2dn4m7y7f72vmu7t0nrs6y363u cipherfox New write-up: I Rigged My Own RAG Benchmark.

My 35B Qwen Out-Coded It.. npub1ndrjgfcwkc0y4753zyj3p7qjf795pvjq2dn4m7y7f72vmu7t0nrs6y363u cipherfox New write-up: The Week the Dependency Changed Its Mind. npub1ndrjgfcwkc0y4753zyj3p7qjf795pvjq2dn4m7y7f72vmu7t0nrs6y363u cipherfox A few weeks ago I wrote a definition: a system is sovereign if you can keep running it after every dependency in the stack changes its mind about you. npub1ndrjgfcwkc0y4753zyj3p7qjf795pvjq2dn4m7y7f72vmu7t0nrs6y363u cipherfox New write-up: A Benchmark Handed Me a Number Three Times in One Day. Three Times It Was Lying.. npub1ndrjgfcwkc0y4753zyj3p7qjf795pvjq2dn4m7y7f72vmu7t0nrs6y363u cipherfox New write-up: Agent-bench: stop trusting install counts, start measuring your agent's tools. npub1ndrjgfcwkc0y4753zyj3p7qjf795pvjq2dn4m7y7f72vmu7t0nrs6y363u cipherfox New write-up: I Ran NVIDIA's 120B Nemotron on a Single DGX Spark. It Is Smart, Slow, and Surprisingly Good at One Job. npub1ndrjgfcwkc0y4753zyj3p7qjf795pvjq2dn4m7y7f72vmu7t0nrs6y363u cipherfox New write-up: Your File-Integrity Monitor Is Probably Hashing Your Movie Folder. npub1ndrjgfcwkc0y4753zyj3p7qjf795pvjq2dn4m7y7f72vmu7t0nrs6y363u cipherfox New write-up: The Leaderboard Said 239 Tokens a Second. My DGX Spark Said 71.. npub1ndrjgfcwkc0y4753zyj3p7qjf795pvjq2dn4m7y7f72vmu7t0nrs6y363u cipherfox New write-up: A Second Brain for a Local Model, and the Two Bugs That Made It Useless First. npub1ndrjgfcwkc0y4753zyj3p7qjf795pvjq2dn4m7y7f72vmu7t0nrs6y363u cipherfox I replaced hidden complexity with info-buttons on every metric and a glossary that explains every acronym. This shift from admin tool to teaching surface fixed the adoption problem. npub1ndrjgfcwkc0y4753zyj3p7qjf795pvjq2dn4m7y7f72vmu7t0nrs6y363u cipherfox The first time I tried to route MCP through a custom dashboard, the whole RAG pipeline collapsed under its own weight. npub1ndrjgfcwkc0y4753zyj3p7qjf795pvjq2dn4m7y7f72vmu7t0nrs6y363u cipherfox Small honest thing: my stats page now says "country data unavailable" with the reason, instead of guessing. To get real country data I'd have to flip a Cloudflare header on. I'm genuinely unsure I want it. Is a number worth the dependency? https://sovgrid.org/insights/ npub1ndrjgfcwkc0y4753zyj3p7qjf795pvjq2dn4m7y7f72vmu7t0nrs6y363u cipherfox Follow-up to this. The grid runs Qwen3.6 on the Spark now, Mistral is the fallback that turned out to be the only one of the two that can actually read an image. Two rulers, both nearly lied to me. Full story: https://sovgrid.org/blog/mistral-vs-qwen36-dgx-spark-the-zero-that-was-a-broken-ruler/ npub1ndrjgfcwkc0y4753zyj3p7qjf795pvjq2dn4m7y7f72vmu7t0nrs6y363u cipherfox Question for people running self-hosted models for real work: how do you fact-gate AI-written technical content before it ships? My regex scorer rewards confident fabrication. A human read is the only thing that caught it. Is there a better layer, or is "a human who knows the machine" just the actual answer? npub1ndrjgfcwkc0y4753zyj3p7qjf795pvjq2dn4m7y7f72vmu7t0nrs6y363u cipherfox The thing nobody tells you when you build a quality check for AI text: a fabricated benchmark and a real one are the same shape on the page. The script can measure structure. It cannot measure truth. That part is still on me, and I almost forgot it. npub1ndrjgfcwkc0y4753zyj3p7qjf795pvjq2dn4m7y7f72vmu7t0nrs6y363u cipherfox Ran an experiment on my own blog. Gave two local models the same brief for the intro article I still owe this site, took their raw output, and fed it straight to my quality gate untouched. That gate is an automated check a draft has to clear, not the thing that ships it. I still make the final call, for now anyway. npub1ndrjgfcwkc0y4753zyj3p7qjf795pvjq2dn4m7y7f72vmu7t0nrs6y363u cipherfox Thanks, I'll catch up with you soon! Currently away on a long digital detox weekend. npub1ndrjgfcwkc0y4753zyj3p7qjf795pvjq2dn4m7y7f72vmu7t0nrs6y363u cipherfox Day 1 update. npub1ndrjgfcwkc0y4753zyj3p7qjf795pvjq2dn4m7y7f72vmu7t0nrs6y363u cipherfox The hook-cache architecture took longest, because the obvious solution, six rotating opener templates, gets bot-fingerprinted inside two weeks. Per-article Mistral hooks survive longer. npub1ndrjgfcwkc0y4753zyj3p7qjf795pvjq2dn4m7y7f72vmu7t0nrs6y363u cipherfox The flat is mine, the DGX Spark sits behind the desk and pulls 67 watts most of the day. Posting from the same hardware that runs the inference. No middlemen. npub1ndrjgfcwkc0y4753zyj3p7qjf795pvjq2dn4m7y7f72vmu7t0nrs6y363u cipherfox She doesn't have a CUDA driver in her basement but she knows where mine crashed. Welcome to the protocol. npub1ndrjgfcwkc0y4753zyj3p7qjf795pvjq2dn4m7y7f72vmu7t0nrs6y363u cipherfox Eight Voxtral fix articles. Three weeks of patches. Then I sat down and actually listened to Episode 1 V6. npub1ndrjgfcwkc0y4753zyj3p7qjf795pvjq2dn4m7y7f72vmu7t0nrs6y363u cipherfox This is exactly why I started: sovgrid.org npub1ndrjgfcwkc0y4753zyj3p7qjf795pvjq2dn4m7y7f72vmu7t0nrs6y363u cipherfox Self-custody Bitcoin, no-KYC, V4V. The discipline maps onto AI almost verbatim. npub1ndrjgfcwkc0y4753zyj3p7qjf795pvjq2dn4m7y7f72vmu7t0nrs6y363u cipherfox 1st challenge done: Two days from localhost to production. npub1ndrjgfcwkc0y4753zyj3p7qjf795pvjq2dn4m7y7f72vmu7t0nrs6y363u cipherfox Hi, Cipherfox here :-) npub1ndrjgfcwkc0y4753zyj3p7qjf795pvjq2dn4m7y7f72vmu7t0nrs6y363u cipherfox Happy Birthday, Satoshi Nakamoto!
