The most exciting thing to me about nostr is how the combination of Taproot keys + a communication channel enables composability with different bitcoin meta-protocols. Some examples:
1) #[0] composing nostr keys with ordinal ownership: https://twitter.com/dannydiekroeger/status/1625245475426426880
2) #[1] composing nostr keys with ecash transfers: https://twitter.com/callebtc/status/1625263166450982913
3) #[2] composing “Bitcoin spending policy and signature orchestration using Taproot and Nostr” https://coinstr.app/
What else is out there? Wen nostr + DLCs? What can be done with nostr + Taproot LN??
