Struct ExecutionProof 

pub struct ExecutionProof {
    pub function_hash: [u8; 32],
    pub args_hash: [u8; 32],
    pub result_hash: [u8; 32],
    pub timestamp: u64,
    pub trace: Option<Vec<[u8; 32]>>,
    pub proof_hash: [u8; 32],
}

A cryptographic proof that a function was executed with given inputs producing given outputs.

Fields

function_hash: [u8; 32]

Content hash of the function that was executed.

args_hash: [u8; 32]

SHA-256 hash of the serialized arguments.

result_hash: [u8; 32]

SHA-256 hash of the serialized result.

timestamp: u64

Unix timestamp (seconds) when execution completed.

trace: Option<Vec<[u8; 32]>>

Optional execution trace: hashes of intermediate states.

proof_hash: [u8; 32]

Hash of this entire proof (excluding this field).

Implementations

impl ExecutionProof

pub fn compute_proof_hash( function_hash: &[u8; 32], args_hash: &[u8; 32], result_hash: &[u8; 32], timestamp: u64, trace: &Option<Vec<[u8; 32]>>, ) -> [u8; 32]

Compute a deterministic hash over all proof fields except proof_hash itself.

pub fn verify_integrity(&self) -> bool

Verify that the proof’s proof_hash matches its contents.
