I'm a fan of bitcoin core up to v29. Consider v30+ risky. But, whatever your disageements please dont encourage denial of service attacks on bitcoin nodes. image

#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. image

Great presentation by Maxim at Honey Badger conference. Great to see the first 1000 smart contracts issued on bitcoin, and the first 200,000 users. Yes, it's mainly testnet, for now. But surely a bright future ahead for programmable bitcoin. image

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! image

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. image

A fairly decent summary. I would add one thing. A nostr client could upgrade its censorship resistance with a relatively easy #pubky integration. The two protocols are complementary. image
