Thomas Thiery: Fossil enhances transaction inclusion in Ethereum, MEV threatens decentralization, and upcoming changes will reshape block construction | Epicenter Fossil improves transaction inclusion guarantees by allowing validators to enforce transaction inclusion in Ethereum blocks. The design of Fossil aims to prevent MEV from compromising censorship resistance. MEV introduces a centralization force among validators, challenging decentralization. Key takeaways Fossil improves transaction inclusion guarantees by allowing validators to enforce transaction inclusion in Ethereum blocks. The design of Fossil aims to prevent MEV from compromising censorship resistance. MEV introduces a centralization force among validators, challenging decentralization. Block building on Ethereum is currently dominated by a few builders, undermining decentralization. MEV refers to the context in which a transaction is placed in a block, affecting transaction ordering. The extractable value from MEV dwarfs the transactions themselves, previously estimated to be around 1% of the transaction volume. Block construction involves searchers creating transaction bundles and builders compiling them into full blocks. The auction process between proposers and builders is mediated by a relay to ensure fair exchanges. A commit and reveal scheme will replace the current relay system in the next Ethereum hard fork. Proposers hold significant power in the auction process, capturing value before redistribution. The Ethereum Foundation is focused on enhancing censorship resistance and transaction inclusion. The upcoming changes in Ethereum’s infrastructure could impact transaction processing dynamics. Guest intro Thomas Thiery is a researcher in the Robust Incentives Group at the Ethereum Foundation, where he focuses on blockchain economics and protocol design. He is the primary architect of FOCIL (Fork-Choice Enforced Inclusion Lists), a mechanism proposed for inclusion in Ethereum’s Hegota upgrade that addresses centralization risks in block production by enabling decentralized validators to enforce transaction inclusion. His work directly tackles the censorship resistance challenges posed by the concentration of block-building power…
