Deep Tide TechFlow news, on June 18, a proposal titled "Confidential Wrapped Ethereum Privacy" was published in the Ethereum research forum. This proposal introduces the concept of Confidential Wrapped Ethereum (cWETH), aiming to achieve privacy protection for ETH transactions at the application layer. cWETH combines the Elliptic Curve Twisted ElGamal commitment mechanism and the Diffie-Hellman protocol, utilizing zk-SNARKs to verify transaction validity, allowing users to make peer-to-peer payments without disclosing balances and transfer amounts. Compared to existing solutions, cWETH improves efficiency by allowing access to encrypted balances without having to solve the discrete logarithm problem. This solution is expected to evolve into a complete confidential token standard (EIP).
