ME News reports that on October 9 (UTC+8), Ethereum Foundation researcher frisitano published a draft EIP. The draft includes proofs that verify the validity of all execution payloads from the head back to the starting beacon block, binding them to the beacon chain. Each proof extends one additional block after validating the previous full payload proof. Public inputs commit to the roots of the starting and head beacon blocks, the chain ID, and the stateless input mode version; only these two roots are broadcast during propagation. Consecutive proofs are chained via beacon state, with the guest program reusing EIP-7732’s envelope processor and verifying through the execution engine. Newer proofs on the same branch include earlier proofs, enabling execution layer synchronization to complete in constant time from a weak subjectivity checkpoint. Proofs are propagated via gossip, with at most one additional minimal request-response protocol serving from a bounded-memory cache. (Source: Foresight News)

Summary
Ethereum news: On October 9 (UTC+8), Ethereum Foundation researcher frisitano published a draft EIP proposing execution layer proofs to enable constant-time synchronization from weak subjectivity checkpoints. The draft outlines recursive verification of execution payloads from the head to the starting beacon block, with each proof validating the prior one before extending to the next block. Public input commitments include the roots of the start and head beacon blocks, chain ID, and the stateless input mode version. Proofs are linked through beacon states, reuse EIP-7732’s envelope processor, and are validated by the execution engine. Newer proofs on the same branch include older ones, enabling constant-time execution layer synchronization from weak subjectivity checkpoints. Proofs are propagated via gossip, with a minimal request-response protocol serving from a bounded-memory cache. This Ethereum ecosystem update highlights a key advancement in layer synchronization efficiency.
