Ethereum is implementing ePBS in Glamsterdam, allowing proposers to outsource block building to a permissionless market, aiming to prevent centralization in staking. The introduction of FOCIL, a multi-participant block building protocol, ensures transaction inclusion by allowing 16 randomly-selected attesters to choose transactions for blocks, mitigating risks of centralization. Further developments include the speculative "Big FOCIL," which could expand attester roles to include all transactions, reducing builders to handling only MEV-relevant transactions. Encrypted mempools are also being explored to combat "toxic MEV" by encrypting transactions until block inclusion, preventing exploitative practices like frontrunning. Efforts are underway to enhance transaction privacy and efficiency at the network layer, with initiatives like Tor routing and custom mixnets. Long-term visions for Ethereum include distributed block building akin to BitTorrent, aiming to process more transactions without centralizing block building, while maintaining synchronous shared state.
