According to @alice_und_bob, Polkadot researchers are developing a consensus upgrade that hides the next block leader via zero-knowledge lotteries to reduce DDoS risk on proposers and improve block production reliability on DOT (source: @alice_und_bob on X). According to @jarrodwatts, Ethereum’s EIP-7917 adds deterministic proposer lookahead so L1 users can obtain reliable, instant pre-confirmations from the next block proposer (source: @jarrodwatts on X). For traders, ETH’s visible proposer schedule enables pre-confirmation guarantees from the next proposer on L1, while DOT’s hidden-leader design focuses on mitigating targeted disruptions to block production (source: @jarrodwatts on X; source: @alice_und_bob on X).
