1. The mistake is that it was merged too soon, without community conensus. So now governance has become a central point of failure.
2. Dont put images in the block chain, put a reference to them instead, and store them off-chain. Alt. narratives are red herrings.
3. This change increases the attack surface, with unclear consequences. That is particularly bad when securing $2 trillion of users savings.
4. Sensible heuristics can limit or make more expensive these non-standard transactions, which is one of the smart things Satoshi figured out.
Still not too late to fix.

Correct! There are a few other useful things in Knots, but that's the main one, right now. It's a 100% compatible drop-in replacement that "just works". You dont have to redownload anything. It's a great choice if you think bitcoin is money.

#mindstr explain the OP_RETURN debate.
Personally I remain a fan of core (and knots) but this PR was merged too early, and is a (rare) mistake from the maintainers. Still time to target v31 and turn a lose-lose into a win-win. FOSS tends to work best when you listen to the community.

Abount 16%, just below the latest core. It was pushback against a very unpopular PR merge. I am not saying there were no lies. But this understandabl push back has now split the node eco system. Oh on hand it makes a split more likely, on the other it may ossify bitcoin. It is something we will have to live with.

Definition: Agentic Web
The Agentic Web is a distributed, interactive internet ecosystem in which autonomous software agents, often powered by large language models, act as autonomous intermediaries that persistently plan, coordinate, and execute goal-directed tasks. In this paradigm, web
resources and services are agent-accessible, enabling continuous agent-to-agent interaction, dynamic information exchange, and value creation alongside traditional human-web interactions.

Good news! After a helpful discussion with the W3C Credentials Community Group, we’ve aligned on a verification method that works cleanly with did:nostr and the Verifiable Credentials stack:
w3c-ccg/community#254 (comment)
I’ve already patched the did:nostr draft to reflect this.
What this unlocks
1. Production-ready reference implementations
2. Compatibility with the wider W3C Credentials ecosystem
3. A straightforward path to issuing industry-standard credentials (badges, awards, driver’s licences, etc.) over Nostr
4. The ability to sign and exchange JSON payloads between Nostr services (relays optional)
It’s a nice step up in standards alignment and Nostr functionality.
Many thanks to everyone who weighed in, feedback very welcome!

Been having a lot of fun exploring smart contracts over Bitcoin. They only launched last week, and wallets are already popping up. One wallet’s chat room has 40,000 people in it, and that’s just one wallet! All this without needing a Bitcoin fork. Feels like we might be at the start of something big.

This quote is true. Nostr was actually the 3rd attempt to add a social layer to bitcoin, the first 2 tries were largely ignored, and in fact probably scaled better. Things can take a long time to notice. Same is true for the best technology today. Smart contracts on bitcoin, launched last week, and mostly ingored, will create the world's first digital free market where humans and machines can participate together.

No, that's ordinals. They are bad. The block chain is not cloud storage. Instead of spamming the block chain with images, you can put a pointer (like a short url) to them. Smart contracts are a full verifiable commerce layer on top of bitcoin. Just as companies and firms have a currency they use. A full digital free market can be built on top of bitcoin. The first fair and open free market the world has seen. It's a big idea.

Bitcoin launched in 2009 with simple payments. 10 years later work began to create smart contract functinality over bitcoin. After a long 6 year wait the first smart contracts were released to main net last week. Now an eco system is growing up building tools, libraries and contracts. Still early, like the very first days of nostr 5-6 years ago. But it improves every day and will hopefully take market share from other chains, back to fair coins such as bitcoin.

SIGIL defines a deterministic envelope that lets any JSON object be hashed and authenticated with a Nostr key‑pair using RFC 8785 canonicalisation and BIP‑340 Schnorr signatures. The envelope keeps the familiar id and pubkey/sig fields while removing the 6‑item Nostr signing tuple, making the format suitable for off‑relay storage, cross‑protocol bridges and application‑specific events.

Replied to a comment about a previous post. Essentaily censorship resistance is not the same as censroship proof. If you want censorship proof you need a network like bittorrent or pubky.

Probably a bad idea, since bookmark data in relays will inevitably get nuked, and users will suffer endless disappoinment when they find out their older bookmarks are gone. Better to use NIP-98 and save the bookmarks in .json in stroage such as NosDAV.
