Expand description

A mutable prover state.

Can be persisted across EvalcheckProver::prove invocations. Accumulates new_sumchecks bivariate sumcheck instances, as well as holds mutable references to the trace (to which new oracles & multilinears may be added during proving)

where F: TowerField + From<PW::Scalar>, PW: PackedFieldIndexable + WithUnderlier, PW::Scalar: TowerField + From<F>, PW::Underlier: PackScalar<PW::Scalar, Packed = PW>, Backend: ComputationBackend,

source

pub fn new( oracles: &'a mut MultilinearOracleSet<F>, witness_index: &'a mut MultilinearExtensionIndex<'b, PW::Underlier, PW::Scalar>, backend: Backend ) -> Self

Create a new prover state by tying together the mutable references to the oracle set and witness index (they need to be mutable because new_sumcheck reduction may add new oracles & multilinears) as well as committed eval claims accumulator.

source

pub fn take_new_sumchecks(&mut self) -> Vec<BivariateSumcheck<'b, F, PW>>

A helper method to move out the set of reduced sumcheck instances

source

pub fn prove( &mut self, evalcheck_claim: EvalcheckClaim<F> ) -> Result<EvalcheckProof<F>, Error>

Prove an evalcheck claim.

Given a prover state containing MultilinearOracleSet indexing into given MultilinearExtensionIndex, we prove an EvalcheckClaim (stating that given composite poly equals eval at eval_point) by recursively processing each of the multilinears in the composition. This way the evalcheck claim gets transformed into an EvalcheckProof and a new set of claims on:

  • PCS openings (which get inserted into BatchCommittedEvalClaims accumulator)
  • New sumcheck instances that need to be proven in subsequent rounds (those get appended to new_sumchecks)

All of the new_sumchecks instances follow the same pattern:

  • they are always a product of two multilins (composition polynomial is BivariateProduct)
  • one multilin (the multiplier) is transparent (shift_ind, eq_ind, or tower basis)
  • other multilin is a projection of one of the evalcheck claim multilins to its first variables
