Vitalik Buterin: FOCIL (anti-censorship inclusion design) and EIP-8141 (Ethereum standards proposal) enable faster, censorship-resistant transactions

Vitalik Buterin highlights how EIP-8141 and FOCIL can complement each other, allowing smart wallet and privacy transactions to be included within 1–2 slots via randomly selected proposers.

Summary

Vitalik Buterin stated that Ethereum’s FOCIL design and the account abstraction proposal EIP-8141 have strong synergies. The combination allows transactions to be included within 1–2 slots, with each slot using a random selection of 17 proposers or includers. FOCIL currently has a size of about 8 kB and differs from MEV 'last look' in ePBS. It supports smart wallet and privacy protocol transactions via the public mempool, aiming to maintain rapid, censorship-resistant inclusion.

Terms & Concepts
  • EIP-8141: An Ethereum standards proposal that enables certain accounts, such as smart wallets, to have native on-chain status, supporting faster and censorship-resistant transaction inclusion.
  • FOCIL: A proposed Ethereum anti-censorship transaction inclusion mechanism that randomly selects proposers or includers to ensure robust, rapid inclusion of transactions.
  • MEV 'last look': A feature in proposer-builder separation (PBS) allowing builders to inspect and potentially adjust transactions before final inclusion, which FOCIL is designed to avoid.
