Ethereum Foundation researcher proposes to increase the number of proposers in a single Ethereum PoS Slot

Michael Neuder, a researcher at the Ethereum Foundation, and Max Resnick, Chief Researcher at SMG, 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 included in a 12-second period, which can change the transaction list and make the second largest blockchain susceptible to centralization issues. Michael Neuder suggests introducing the simplest version of the "dual proposer construction" into the Slot, electing two validators as eligible proposers of blocks. According to previous reports, Ethereum may see more changes in its validation design after the 2024 Dencun upgrade. Currently, the validator deposit issue has been added to the Electra hard fork agenda from the fourth quarter of 2024 to the first quarter of 2025.
