Struct snarkvm_polycommit::sonic_pc::SonicKZG10 [−][src]
pub struct SonicKZG10<E: PairingEngine> { /* fields omitted */ }
Expand description
Polynomial commitment based on [KZG10], with degree enforcement and batching taken from [MBKM19, “Sonic”] (more precisely, their counterparts in [Gabizon19, “AuroraLight”] that avoid negative G1 powers). The (optional) hiding property of the commitment scheme follows the approach described in [CHMMVW20, “Marlin”].
