Struct RingSwitchPCS

source
pub struct RingSwitchPCS<F, FDomain, PE, DomainFactory, Inner> { /* private fields */ }
Expand description

A polynomial commitment scheme constructed as a reduction to an inner PCS over a field extension.

This implements the Construction 4.1 in DP24. The polynomial is committed by committing its corresponding packed polynomial with the inner PCS. Evaluation proofs consist of a sumcheck reduction followed by a PCS evaluation proof for the packed polynomial using the inner PCS.

§Type parameters

  • F - the coefficient subfield
  • FDomain - the field containing the sumcheck evaluation domains
  • PE - a packed extension field of F that is cryptographically big
  • DomainFactory - a domain factory for the sumcheck reduction
  • Inner - the inner polynomial commitment scheme over the extension field
