In total, there are three parts：
-
circuit/README.md: Provide two simple circuits (similar to hello world) with potentially multiple solutions for each commitment.
-
contract/README.md: Support for arbitrarily many circuits vk, as well as commitment. Each commitment has a corresponding reward, which is earned by providing the correct proof.
-
frontend/README.md: verifying_key, proof, commitment are generated through the circuit module command line, and then interact with the sui contract through the frontend module.
