A nostr-did can go in a wallet with your sats, and digital art. The did itself could be any nostr account or sub account you own, or a friendly agent that does stuff for you. image

Stating the obvious: Miners should transparently prioritize financial transactions over image storage and spam transactions. They already have all the tools they need to do this. image

💡Threadlocks: One-Time Commitments with Bitcoin and Nostr What if you could make a promise, cryptographically bind it to Bitcoin, and close it forever with one action — all while broadcasting its intent through Nostr? 🧪 Use Cases Threadlocks enable: ✅ One-time claims ("I minted this", "I voted") 🔐 Access control (only those with unspent Threadlocks can act) 🗳️ DAO governance (commit → vote → finalize) 🎮 Game state progression (quests, puzzles, unlocks) 🧾 Credential issuance (proof of training, rights, NFTs)

I'm increasingly impressed with what can be vibe coded these days. Now it has learnt to deploy simple backends. Still a ways to go, but the future looks promising. image

There are few feelings like waiting 119 years to win a trophy. A true fairy tail incluing twice heartbreak, creation of the devil, and coming back from a 9-0 defeat. Well done Crystal Palace!

If we had someone who could act as an honest Oracle, we could make an AMM for this event on nostr using digital signatures, and on-chain commitments. People could bet on the team of their choice, and the odds would adjust according to how much is staked. At the end the contract pays out to all the bets made. However, you you need someone impartial to report the winner of the tournament. If the wrong winner is called the funds would go to the wrong place. View quoted note →

Nostr + Bitcoin: Built-in Time Boxing 1. Your npub is a BTC address. 2. Pay npub (event hash in tx) -> means NOT-BEFORE block time. 3. Spend output -> means NOT-AFTER block time. Now Events are time-boxed between two blocks. It turns out that this is all you need to solve the double-spend problem. And hence to unlock smart social contracts. image
