Detailed Description

template<typename ppT>
class libsnark::r1cs_ppzksnark_proof< ppT >

A proof for the R1CS ppzkSNARK.

While the proof has a structure, externally one merely opaquely produces, serializes/deserializes, and verifies proofs. We only expose some information about the structure for statistics purposes.
