Struct ExecutionWitnessRecord 

Source 
pub struct ExecutionWitnessRecord {
    pub hashed_state: HashedPostState,
    pub codes: Vec<Bytes>,
    pub keys: Vec<Bytes>,
    pub lowest_block_number: Option<u64>,
}
Available on crate feature witness only.
Expand description

Tracks state changes during execution.

Fields§

§hashed_state: HashedPostState

Records all state changes

§codes: Vec<Bytes>

Map of all contract codes (created / accessed) to their preimages that were required during the execution of the block, including during state root recomputation.

keccak(bytecodes) => bytecodes

§keys: Vec<Bytes>

Map of all hashed account and storage keys (addresses and slots) to their preimages (unhashed account addresses and storage slots, respectively) that were required during the execution of the block.

keccak(address|slot) => address|slot

§lowest_block_number: Option<u64>

The lowest block number referenced by any BLOCKHASH opcode call during transaction execution.

This helps determine which ancestor block headers must be included in the ExecutionWitness.

None - when the BLOCKHASH opcode was not called during execution
