【以太坊隐私新方案 cWETH 草案发布】6月18日消息，一则名为"Confidential Wrapped Ethereum Privacy"的提案在以太坊研究论坛发布。该提案介绍了机密版包装以太坊(cWETH)的概念，旨在通过应用层实现 ETH 交易的隐私保护。cWETH 结合椭圆曲线 Twisted ElGamal 承诺机制和 Diffie-Hellman 协议，并利用 zk-SNARKs 验证交易合法性，使用户能够在不泄露余额和转账金额的情况下进行点对点支付。 与现有方案相比，cWETH 无需解决离散对数问题即可访问加密余额，提高了效率。该方案有望发展成为完整的机密代币标准(EIP)。
