Implementations§

impl<P> ArithmeticCircuit<P>
where P: Fn(PartitionType, usize) -> Option<usize>,

pub fn commit(&self, v: &[Scalar], s: &Scalar) -> ProjectivePoint

Creates commitment to the arithmetic circuit witness.

pub fn verify( &self, v: &[ProjectivePoint], t: &mut Transcript, proof: Proof, ) -> bool

Verifies arithmetic circuit proof with respect to the v commitments vector.

pub fn prove<R>( &self, v: &[ProjectivePoint], witness: Witness, t: &mut Transcript, rng: &mut R, ) -> Proof
where R: RngCore + CryptoRng,

Creates arithmetic circuit proof for the corresponding witness. Also, v commitments vector should correspond input witness in witness argument.
