TechFlow reports on March 2 that Ethereum researcher "Malik672" proposed a "decentralized random block proposal" aimed at eliminating MEV and addressing centralization issues.
The research highlights that currently around 80% of Ethereum blocks are proposed by just two entities, undermining the network's decentralized nature.
The proposal suggests all Ethereum clients use the same randomized algorithm to build blocks, reaching consensus via a Byzantine fault-tolerant mechanism. This system would eliminate maximum extractable value (MEV) at the block level, distributing block proposal rights from a few builders to thousands of clients worldwide, while remaining compatible with sharding technology.
Compared to the current proposer-builder separation (PBS) mechanism, this system prioritizes trustlessness over optimization, potentially reducing Ethereum's block time from 12 seconds to 6–8 seconds, though possibly at the cost of some Layer 2 efficiency. The researcher argues this trade-off is worthwhile for an Ethereum that values fairness and decentralization.
