Detailed Description

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

The command

$

libsnark/zk_proof_systems/ppzksnark/uscs_ppzksnark/profiling/profile_uscs_ppzksnark 1000 10 Fr

exercises the ppzkSNARK (first generator, then prover, then verifier) on an USCS 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/uscs_ppzksnark/profiling/profile_uscs_ppzksnark 1000 10 bytes

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