Detailed Description

Profiling program that exercises the ppzkSNARK (first generator, then prover, then verifier) on a synthetic R1CS instance.

The command

$

libsnark/zk_proof_systems/ppzksnark/r1cs_ppzksnark/profiling/profile_r1cs_ppzksnark 1000 10 Fr

exercises the ppzkSNARK (first generator, then prover, then verifier) on an R1CS instance with 1000 equations and an input consisting of 10 field elements.

(If you get the error zmInit ERR:can't protect, see the discussion above.)

The command

$

libsnark/zk_proof_systems/ppzksnark/r1cs_ppzksnark/profiling/profile_r1cs_ppzksnark 1000 10 bytes

does the same but now the input consists of 10 bytes.
