Struct ConstraintCommitment

Source 
pub struct ConstraintCommitment<E: FieldElement, H: ElementHasher<BaseField = E::BaseField>, V: VectorCommitment<H>> { /* private fields */ }
Expand description

Constraint evaluation commitment.

The commitment consists of two components:

  • Evaluations of composition polynomial columns over the LDE domain.
  • Vector commitment where each vector element corresponds to the digest of a row in the composition polynomial evaluation matrix.

Implementations§

Source§

impl<E, H, V> ConstraintCommitment<E, H, V>
where E: FieldElement, H: ElementHasher<BaseField = E::BaseField>, V: VectorCommitment<H>,

Source

pub fn new( evaluations: RowMatrix<E>, commitment: V, ) -> ConstraintCommitment<E, H, V>

Creates a new constraint evaluation commitment from the provided composition polynomial evaluations and the corresponding vector commitment.

Source

pub fn commitment(&self) -> H::Digest

Returns the commitment.

Source

pub fn query(self, positions: &[usize]) -> Queries

Returns constraint evaluations at the specified positions along with a batch opening proof against the vector commitment.
