Ethereum developers are testing a zero-knowledge (ZK)-based privacy protocol enabling on-chain “Secret Santa”–style anonymous matching. Participants use ZK proofs to verify relationships, relayers to hide transaction origins, and shared randomness to encrypt gift messages, preventing address exposure, duplicate registration, or self-matching. The protocol is seen as a key step in Ethereum’s privacy framework, with potential applications in anonymous voting, DAO governance, whistleblowing, and private airdro ...
