Since #145 is a huge PR, I would like to separate it into several parts. This PR adds traits
Witness{Var}ExtandCommittedInstance{Var}Ext, serving as abstractions for witnesses and committed instances in Nova, HyperNova and ProtoGalaxy.Looking ahead, the methods in these traits are going to be used by the unified generic decider circuit in #145.
Also, the
hashmethod inCommittedInstance{Var}Exthas a default implementation, so we can eliminate the duplicated code ofhashfor Nova'sCommittedInstance, HyperNova'sLCCCS, and ProtoGalaxy'sCommittedInstance.The signature of
hashis also changed, wherez_0andz_iare now slices rather than owned vectors.In this way, we can avoid cloning
z_iin augmented circuits, asz_imight be very large.
