Abstract
This EIP introduces Payload Chunking, a protocol upgrade that restructures Ethereum block propagation into self-contained execution chunks with separated Chunk Access Lists (CALs). The proposer propagates beacon and execution payload headers, followed by CALs and chunks as independent network messages. CALs contain state diffs from chunk execution, enabling parallel chunk validation: chunk N can…
