According to online reports, Ethereum co-founder Vitalik Buterin shared the Ethereum L1 Simple Privacy Roadmap. These include the idea of effectively improving the privacy of Ethereum users without changing the Ethereum Consensus, and focus on four forms of privacy: on-chain payment privacy, partial anonymity of on-chain activities within applications, on-chain reading privacy, and network anonymity. Solutions include integrating privacy tools such as Railgun into wallets, default to "one address per application", implementing FOCIL and EIP-7701, and using TEE and PIR technology to protect RPC privacy, aiming to improve user privacy and reduce metadata leakage.
