Ethereum developers have drafted the EIP-7917 proposal, aimed at addressing the uncertainty issues in the existing proposer election process.

According to Wu, Ethereum developers @linoscope and @JustinDrake have jointly drafted the EIP-7917 proposal (Deterministic Proposer Lookahead), which aims to fundamentally resolve the uncertainty issues in the current proposer election process. In the current Ethereum consensus, the system selects a validator as the block proposer for a given slot from the entire active validator set using a random sampling algorithm based on random numbers (such as RANDAO) and effective balance. Although the RANDAO seed can be obtained in advance, the effective balance of validators may fluctuate within an epoch, making it difficult to fully predict the proposer for the next epoch, posing risks to on-chain applications based on pre-confirmation protocols. EIP-7917 addresses the uncertainty in proposer arrangements caused by the dynamic changes in validators' effective balances by precomputing and storing a deterministic proposer list at the beginning of each epoch. This not only enhances the security of the system, preventing validator manipulation, but also simplifies the implementation of on-chain protocols while maintaining backward compatibility and scalability.
