Ethereum Research Proposes Solution to Combat Centralization Issues

Ethereum’s ongoing research into decentralization addresses a significant issue within its current architecture, where centralized power has concentrated among just a few entities, undermining the network’s foundational goals. Even with the transition to Proof of Stake (PoS) and the adoption of Proposer-Builder Separation (PBS), a troubling concentration persists: approximately 80% of Ethereum blocks are proposed by only two entities. This concentration allows these entities to control most of the maximum extractable value (MEV), giving them disproportionate influence over the network.

To address this issue, new research proposes a decentralized random block proposal system. The core idea of this system is to move away from specialized builders creating blocks and instead have all Ethereum clients (e.g., Geth, Nethermind) use a standardized random algorithm to select transactions and roll-up blobs from their local mempools. This randomization would eliminate predictability in transaction ordering, making it far more difficult for any entity to control or manipulate the block-building process. Consequently, this would reduce MEV opportunities, such as arbitrage and front-running, which currently benefit a few centralized actors.

Additionally, this proposed randomization could lower Ethereum’s block time, potentially reducing it from the current 12 seconds to between 6-8 seconds, which would also support the future requirements of Danksharding, Ethereum’s sharding proposal.

This push for more decentralization is happening at a time when the Ethereum Foundation is undergoing leadership changes, which some view as a critical turning point in Ethereum’s evolution. Core developer Tim Beiko has highlighted the importance of these changes, particularly the appointments of Hsiao-Wei Wang and Tomasz Stanczak as co-executive directors of the Ethereum Foundation. Wang’s seven years of experience as an Ethereum researcher, notably contributing to the Beacon Chain, and Stanczak’s background as a developer and leader at Nethermind, are seen as valuable assets in steering the project forward.

While Beiko expressed optimism about these new appointments, he also acknowledged that Ethereum faces many challenges. He emphasized the need to balance optimization with the preservation of Ethereum’s core values, ensuring that the network remains both efficient and faithful to the ideals that made it successful in the first place. Despite the progress, Beiko reminded the community that significant work remains to achieve Ethereum’s ambitious goals.
