Promote with Leviathan NewsTL;DR: Vitalik Buterin outlines Ethereum’s evolving block-building roadmap, starting with ePBS to separate proposers from builders and prevent staking centralization, while tackling builder centralization itself. Short term, FOCIL introduces randomly selected attesters who can force transaction inclusion to resist censorship, with “Big FOCIL” potentially expanding this toward multi-party block construction. Other focus areas include encrypted mempools to reduce toxic MEV (like sandwiching), improving the transaction ingress layer with network-level privacy protections, and exploring long-term distributed block building that preserves Ethereum’s shared state while making most activity cheaper and less globally dependent.
