Ethereum Privacy Upgrade: ZKSS protocol makes on-chain transactions like a "Secret Santa" game

Ethereum is迎 coming a privacy revolution, with the zero-knowledge secret Santa (ZKSS) protocol released by Distributed Lab enabling the verification of transaction validity while ensuring transaction confidentiality. This protocol utilizes zk-SNARKs to hide the identification of the sender and receiver, while also addressing double voting and insufficient randomness issues, achieving on-chain private transactions.

The working mechanism of ZKSS is similar to the secret Santa game: participants submit anonymous random values for gift distribution, and transactions are verified while maintaining privacy. This process combines hash functions, ECDSA signatures, and Merkle proofs to ensure that operations are secure and tamper-proof. Enterprises and institutions can conduct confidential transactions through this protocol while retaining audit trails, reducing the risk of supply chain and financial information being disclosed.

The development of privacy technology has also benefited from regulatory pressure. The Financial Stability Board (FSB) has warned that strict privacy laws may hinder global cooperation on cryptocurrency regulation, while the European Union will require exchanges and wallet providers to report cryptocurrency asset holdings and verify the identification of large transfers starting in 2026. Vitalik Buterin emphasized the importance of metadata privacy protection and donated nearly $390,000 to the decentralized communication application Session to support permissionless privacy accounts.

The Ethereum privacy upgrade marks the transition of the blockchain from a completely transparent ledger to a platform for confidential operations. By combining privacy smart contracts such as RAILGUN and Aztec, users can create shielded balances, enabling controllable private transaction records. As the demand for institutional adoption grows and regulatory pressures increase, zk-SNARKs technology will become a key driving force in promoting the development of the Ethereum ecosystem and the entry of enterprises.
