On June 18th, a proposal titled "Confidential Wrapped Ethereum Privacy" was released on the Ethereum Research Forum. The proposal introduces the concept of Confidential Wrapped Ethereum (cWETH), which aims to achieve privacy protection of ETH transactions through the application layer. cWETH combines the Elliptic Curve Twisted ElGamal commitment mechanism and the Diffie-Hellman protocol, and uses zk-SNARKs to verify the legitimacy of transactions, enabling users to make peer-to-peer payments without revealing balances and transfer amounts.
Compared to existing schemes, cWETH can access crypto balances without solving the discrete logarithm problem, improving efficiency. This scheme is expected to develop into a complete confidential token standard (EIP).
