Grand Prize:
25 Million Sats
Nostr Veil
A privacy extension for NIP-85 that layers ring-signature anonymity onto standard trust score events. Using LSAG ring signatures on secp256k1, trust circles can collectively score subjects while keeping individual contributors anonymous. Backwards compatible — any NIP-85 client displays the scores normally. 118 tests, full NIP-85 kind coverage, independently published npm cryptographic primitives.
