CommitterKey is used to commit to, and create evaluation proofs for, a given polynomial.

Fields

powers_of_beta_g: Vec<E::G1Affine>

The key used to commit to polynomials.

lagrange_bases_at_beta_g: BTreeMap<usize, Vec<E::G1Affine>>

The key used to commit to polynomials in Lagrange basis.

powers_of_beta_times_gamma_g: Vec<E::G1Affine>

The key used to commit to hiding polynomials.

shifted_powers_of_beta_g: Option<Vec<E::G1Affine>>

The powers used to commit to shifted polynomials. This is None if self does not support enforcing any degree bounds.

shifted_powers_of_beta_times_gamma_g: Option<BTreeMap<usize, Vec<E::G1Affine>>>

The powers used to commit to shifted hiding polynomials. This is None if self does not support enforcing any degree bounds.

enforced_degree_bounds: Option<Vec<usize>>

The degree bounds that are supported by self. Sorted in ascending order from smallest bound to largest bound. This is None if self does not support enforcing any degree bounds.

max_degree: usize

The maximum degree supported by the UniversalParams from which self was derived
