[Vitalik: Ethereum to Address Privacy and Data Issues This Year] Foresight News reports that Vitalik Buterin tweeted that by 2026, Ethereum will systematically address issues related to privacy and data. This includes reducing the barrier for running full nodes with ZK-EVM and BAL; verifying the authenticity of RPC returned data through Helios; using ORAM and PIR to request data from RPC without revealing specific content; promoting social recovery wallets and time locks to reduce the risk of fund loss after private key compromise; achieving privacy payments consistent with the experience of regular transfers; enhancing privacy and censorship resistance under ERC-4337, future native account abstraction, and FOCIL; and advancing on-chain application interfaces based on IPFS to reduce reliance on centralized servers.
