An Ethereum researcher, known by the pseudonym “Malik672,” has unveiled a potential solution to address centralization in Ethereum’s block proposal process, suggesting it could also mitigate Maximal Extractable Value (MEV) at the block level. The proposed “Decentralized Random Block Proposal” system aims to democratize the process by utilizing a shared random algorithm which leverages Byzantine Fault Tolerance (BFT). This could eradicate MEV, which is achieved through transaction reordering or censorship, enabling profit-driven strategies like arbitrage and front-running that disadvantage average network users.
Malik672 noted that while Ethereum’s proof-of-stake model and the proposer-builder separation have somewhat diluted MEV concentration, an increasing centralization around two entities, Beaverbuild and Titan Builder, remains a concern. These entities were responsible for producing 88.7% of Ethereum blocks in October, a figure that has since dropped to 80% yet still signifies significant centralization.
The proposed system would decentralize block building across thousands of clients worldwide, preventing any single entity from dominating the process. Unlike the existing Proposer-Builder Separation (PBS) builder pool, this approach would ensure a fairer, more robust system to counter mempool variance. The random block proposal method could also accelerate transaction propagation.
Aligning with Ethereum’s decentralization ethos, Malik672 claims the solution would be compatible with Ethereum’s scaling initiatives, such as Danksharding, and could even reduce block slot times from 12 to 6-8 seconds. This proposal comes as Ethereum developers and researchers have agreed to hasten upgrades to expedite Ethereum’s technical progress.
