Wu Shuo learned that Ethereum developers @ linoscope and @ JustinDrake have jointly drafted the EIP-7917 proposal (Deterministic Proposer Preview | Deterministic Proposer lookahead), aiming to completely solve the uncertainty problem of existing proposer elections. In the current Ethereum consensus, the system selects a validator from the entire set of active validators as the block proposer for the slot through a random sampling algorithm based on random numbers (such as RANDAO) and effective balance weighting. Although the RANDAO seed can be obtained in advance, the validator's effective balance may fluctuate within an epoch, making it difficult to fully predict the proposer for the next epoch, which poses a risk to on chain applications based on pre confirmation protocols. EIP-7917 solves the problem of proposer scheduling uncertainty in existing designs due to dynamic changes in verifier effective balances by pre calculating and storing a deterministic proposer list at the beginning of each epoch. This not only improves the security of the system and prevents validator manipulation, but also simplifies the implementation of on chain protocols while maintaining backward compatibility and scalability. https://www.
