The Holy Trinity of Censorship Resistance in Ethereum

Thu, Jun 19, 2025, 02:03 PM · 23:04

Censorship resistance and decentralization have long been core principles of public blockchains, yet Ethereum faces increasing threats from real-time transaction censorship, particularly impacting DeFi users. The current Proposer-Builder Separation (PBS) supply chain has led to severe centralization, with two builders controlling over 80% of blocks and half of all relays censoring transactions. A promising approach to address this is the ""Holy Trinity of Censorship Resistance"", a combination of enshrined PBS (ePBS), FOCIL (Fork-Choice enforced Inclusion Lists), and encrypted mempools.
