Ecash zaps:
- Receiver (R) announces on their nostr profile which mints they're on
- R posts something dope on nostr
- Sender (S) mints P2PK-locked ecash from R's mint to R's nostr pubkey
- S attaches locked ecash to R's post
- Observer (O) sees ecash attached to R's note and verifies P2PK lock ("receiver is R") and DLEQ proof ("ecash is legit").
- O's nostr client shows "1234 sats zapped from S to R"
Crazy cool does this work on Damus or just Snort
It doesn't work anywhere unfortunately, I couldn't find the time to write the nostr spec and implement the necessary things in Cashu-TS, but the Cashu protocol is already there :)
guess I need to finish nut-11 implementation
This is missing double spending protection, the same valid ecash could be sent to a bunch of notes of the same author, the sender only looses 1 sat, but an observer sees 100000 sat zaps.
