The research paper proposes a decentralized system to replace Ethereum's current centralized block-building model, aiming to eliminate MEV risks and enhance participation. The current Proposer-Builder Separation (PBS) framework has led to centralization, with two entities controlling 80% of block production. The proposed system suggests using a Byzantine Fault Tolerance (BFT)-backed system where all clients propose blocks via a shared random algorithm, thereby restoring decentralization. The system aims to eliminate block-level MEV by randomizing block construction, distributing block-building across numerous clients. While it prioritizes decentralization over optimization, it may sacrifice some rollup efficiency. The conclusion discusses the choice between scalability and egalitarian ideals for Ethereum, with future work focusing on testing synchronization and optimizing rollups.
