Wu Shuo learned that Vitalik Buterin, co-founder of Ethereum, shared a simple privacy roadmap for Ethereum L1. This includes the idea of effectively improving the privacy status of Ethereum users without changing the Ethereum consensus, and focuses on four forms of privacy: on chain payment privacy, partial anonymization of on chain activities within applications, on chain read privacy, and network anonymity. The solution includes integrating privacy tools such as Railgun into the wallet, default 'one address per application', implementing FOCIL and EIP-7701, and using TEE and PIR technologies to protect RPC privacy, aiming to enhance user privacy and reduce metadata leakage. https://www.
