Struct BatchSumcheckOutput

Source

pub struct BatchSumcheckOutput<F> {
    pub batch_coeff: F,
    pub eval: F,
    pub challenges: Vec<F>,
}

Expand description

The reduced output of a sumcheck verification.

The batch_verify function reduces a set of claims on multivariate polynomials over the boolean hypercube to their evaluation at a challenge point. See the function docstring for details.

Fields§

§batch_coeff: F

The challenge value of the batching variable.

§eval: F

The evaluation of the sumcheck multivariate at the challenge point.

§challenges: Vec<F>

Verifier challenges for each round of the sumcheck protocol.

One challenge is generated per variable in the multivariate polynomial, with challenges[i] corresponding to the i-th round of the protocol.

Note: reverse when folding high-to-low to obtain evaluation claim.
