Ethereum Foundation researcher proposes increasing the number of proposers in a single Ethereum PoS slot

Ethereum Foundation researcher Michael Neuder and SMG Chief Researcher Max Resnick proposed to increase the number of proposers in a single Ethereum PoS slot in their article "Concurrent Block Proposers in Ethereum." Currently, block proposers have unilateral power over the transaction set contained within a 12-second period, which can change the transaction list, making it easy for the second largest blockchain to trigger centralization issues. Michael Neuder suggests introducing the simplest version of "dual proposer construction" into slots by electing two validators as eligible block proposers. According to previous reports, Ethereum may see more changes in validation design after the 2024 Dencun upgrade. The validator deposit issue has already been added to the Electra hard fork agenda from Q4 2024 to Q1 2025.
