Struct ExecutionWitnessV1 

Source 
pub struct ExecutionWitnessV1 {
    pub state: Vec<WitnessNodeV1>,
    pub codes: Vec<WitnessCodeV1>,
    pub headers: Vec<WitnessHeaderV1>,
}
Expand description

Canonical execution witness for POST /payloads/witness.

state and codes are produced in lexicographic ascending byte order. headers are RLP-encoded and ordered by ascending block number; consecutive headers must be parent-linked. These ordering rules are producer-side requirements from the execution-specs witness builder.

This is a REST-SSZ wire container, not the JSON-RPC debug witness shape.

Fields§

§state: Vec<WitnessNodeV1>

Hashed trie-node preimages required during execution and state-root recomputation.

§codes: Vec<WitnessCodeV1>

Contract bytecode preimages required from the pre-state.

§headers: Vec<WitnessHeaderV1>

RLP-encoded ancestor headers used for pre-state and BLOCKHASH correctness proofs.
