Ethereum Plans Anti-Censorship Mechanism FOCIL for 2026
With the Hegota upgrade, validators will be required to process valid transactions in the future – Buterin sees this as a crucial step toward censorship resistance.
Ethereum developers have announced FOCIL (Fork-Choice Enforced Inclusion Lists) as a central component of the Hegota upgrade for the second half of 2026. The mechanism is designed to require validators to consider all valid transactions from public mempools [1].
In conjunction with proposal EIP-8141, FOCIL enables "censorship-resistant, rapid inclusion of any transaction," explained Ethereum co-founder Vitalik Buterin. Smart accounts would thereby become full-fledged protocol participants. Transactions from smart wallets, gas-sponsored and privacy protocol transactions could be processed through one of 17 randomly selected actors per slot – typically within one to two slots [1].
The network thus gains the ability to reject blocks if validators deliberately omit certain valid transactions. This is intended to prevent individual validators from systematically blocking transactions, such as those from sanctioned addresses [1].
Ethereum developer Ameen Soleimani expressed concerns that the intervention could expose validators to incalculable risks. Other developers, however, point to the importance of censorship resistance as a fundamental principle of the network [1].
