以太坊開發者正測試一套基於零知識證明（ZK）的隱私協議，用於在鏈上實現「Secret Santa」（秘密聖誕老人）模式的匿名配對。參與者透過 ZK 驗證關係、中繼器隱藏交易來源，並使用共享隨機數加密收禮資訊，藉此避免地址暴露、重複註冊或自我配對的問題。該協議被視為以太坊隱私框架的重要落地案例，未來可進一步延伸至匿名投票、DAO 治理、吹哨管道、私密空投等場景。

Ethereum developers are testing a privacy protocol based on Zero-Knowledge Proofs (ZK) to enable 'Secret Santa'-style anonymous matching on the blockchain. Participants use ZK to verify relationships, relayers to hide transaction origins, and shared random numbers to encrypt gift recipient information—effectively preventing address exposure, duplicate registrations, or self-matching. This protocol is regarded as a key implementation of Ethereum’s privacy framework and can be further extended to scenarios such as anonymous voting, DAO governance, whistleblowing channels, and private airdrops.
