Tokamak zk-EVM: CLI and proving pipeline to convert Tokamak Layer 2 transactions into zk-SNARK proofs

Example circuits for circom 2.0

Implementation KZG zk-SNARKs protocol Marlin and Plonk in Python/SageMath

This example uses the libsnark library to define an R1CS (Rank-1 Constraint System) that represents a simple circuit, where the output is the product of two input values. It then generates a proof for this circuit using the ppzkSNARK proof system provided by libsnark, and verifies the proof using the same library.
