1/6 What is EIP-7917? It’s an Ethereum proposal that makes the block proposer schedule fully deterministic, meaning we’ll know, ahead of time, exactly who is proposing each block. 2/6 Right now, proposer schedules are partly unpredictable. Ethereum uses RANDAO, a built-in randomness source, to fairly assign validators to propose blocks and perform other duties on the Beacon Chain. Even though RANDAO seeds are known in advance, sudden changes in validator balances can shift who becomes proposer, even at the last second. That unpredictability causes problems. 3/6 EIP-7917 fixes it. How does it work? At the start of each epoch, Ethereum creates a list called proposer_lookahead showing which validators will propose blocks for the current and upcoming epochs. When a new epoch starts, the list updates by removing old proposers and adding new ones. This list is stored on-chain, so smart contracts can easily see who proposes next, making confirmations faster and more reliable. Simple, yet brilliant! 4/6 Why it matters? • It boosts Layer 2 solutions by making preconfirmation protocols simpler and more reliable, which supercharges based rollups. • Predictable proposer schedule. • Cleaner design: Resolves a long-standing beacon chain inconsistency. 5/6 Connection with other EIPs. EIP-7917 is joining seven other EIPs in the lineup. It’ll debut in the fusaka-devnet-1 release, set to launch June 9. Devs call it a “minimal lift” with outsized impact, just 22 lines of spec code to unlock all these goodies. 6/6 Ethereum is evolving fast. Fusaka is just one more step. Ethereum just keeps getting better. EIP-7917 is the kind of upgrade that makes Ethereum feel more complete. What do you want to see fixed or improved next?
