Struct ExecutionProof 

pub struct ExecutionProof {
    pub proof: Vec<u8>,
    pub hash_fn: HashFunction,
    pub pc_requests: Vec<PrecompileRequest>,
}

A proof of correct execution of Miden VM.

The proof contains the STARK proof, the hash function used during proof generation, and a set of precompile requests deferred during proof generation. However, the proof does not contain public inputs needed to verify the proof.

Fields

proof: Vec<u8>

hash_fn: HashFunction

pc_requests: Vec<PrecompileRequest>

Implementations

impl ExecutionProof

pub const fn new( proof: Vec<u8>, hash_fn: HashFunction, pc_requests: Vec<PrecompileRequest>, ) -> Self

Creates a new instance of ExecutionProof from the specified STARK proof, hash function, and list of all deferred PrecompileRequests.

pub fn stark_proof(&self) -> &[u8]

Returns the underlying STARK proof.

pub const fn hash_fn(&self) -> HashFunction

Returns the hash function used during proof generation process.

pub fn precompile_requests(&self) -> &[PrecompileRequest]

Returns the list of precompile requests made during the execution of the program.

pub fn security_level(&self) -> u32

Returns conjectured security level of this proof in bits.

Currently returns a hardcoded 96 bits. Once the security estimator is implemented in Plonky3, this should calculate the actual conjectured security level based on:

• Proof parameters (FRI folding factor, number of queries, etc.)
• Hash function collision resistance
• Field size and extension degree

pub fn to_bytes(&self) -> Vec<u8>

Serializes this proof into a vector of bytes.

pub fn from_bytes(source: &[u8]) -> Result<Self, DeserializationError>

Reads the source bytes, parsing a new proof instance.

The serialization layout matches the Serializable implementation of ExecutionProof.

pub fn into_parts(self) -> (HashFunction, Vec<u8>, Vec<PrecompileRequest>)

Returns components of this execution proof.

Trait Implementations

impl Clone for ExecutionProof

fn clone(&self) -> ExecutionProof

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ExecutionProof

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Deserializable for ExecutionProof

fn read_from<R: ByteReader>( source: &mut R, ) -> Result<Self, DeserializationError>

Reads a sequence of bytes from the provided source, attempts to deserialize these bytes into Self, and returns the result.

fn min_serialized_size() -> usize

Returns the minimum serialized size for one instance of this type.

fn read_from_bytes(bytes: &[u8]) -> Result<Self, DeserializationError>

Attempts to deserialize the provided bytes into Self and returns the result.

fn read_from_bytes_with_budget( bytes: &[u8], budget: usize, ) -> Result<Self, DeserializationError>

Deserializes Self from bytes with a byte budget limit.

impl PartialEq for ExecutionProof

fn eq(&self, other: &ExecutionProof) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serializable for ExecutionProof

fn write_into<W: ByteWriter>(&self, target: &mut W)

Serializes self into bytes and writes these bytes into the target.

fn to_bytes(&self) -> Vec<u8>

Serializes self into a vector of bytes.

fn get_size_hint(&self) -> usize

Returns an estimate of how many bytes are needed to represent self.
