@walletsardine and @anchorwatch are building/have timelock capabilities, but theyre the only ones i know of. the reasons for this are a bit complex

10 relays? Sounds decentralized to me unless they’re all run by the same person/entity. How many do you suggest are needed to actually be decentralized?

Clearly written specifications are becoming just as good as code, now that the more advanced LLMs are starting to produce high quality code just from a spec doc. Latest chatgpts can input NIPs and produce working demos. Its wild.

Great explainer. Does any wallet implement access to CLTV for the regular user? I don’t think so but maybe Nostr knows.

you fkn know it!

Satoshi Nakamoto proved that the world can become a better place on a perfect monetary system. He gave us #Bitcoin. And disappeared.

The state takes half of everything you earn and redistributes it arbitrarily, inequitably and inefficiently, paying the 'ruling class' handsomely in the process. Hodl your #Bitcoin

Absolutely! 32k sats and it’s yours shipped Monday!

Navigating #Bitcoin with an ETF on Wall Street? Tougher than it sounds! Why? #Bitcoin never sleeps - it's a 24/7/365 game, but Wall Street? Not so much. This mismatch means potential missed opportunities when the market moves while the stock market's closed. 🌙☀️ The downside? It could limit gains for those trading within the confines of the #USDollar stock market hours. Thoughts? #ETFs #WallStreetVsBitcoin Let's debate! 💬🔥 . .

Possibly!! I’ll check, might be in budget! You ship to California?
