Keyless ZK circuit and ZK proving service

This repo contains:

1. The circom implementation of the Aptos Keyless ZK relation from AIP-61 in circuit/templates/
2. An implementation of a ZK proving service in prover/
3. A circom unit testing framework in circuit/
4. Some shared rust code in keyless-common/
5. A VK diff tool in vk-diff (see its README)

Submodules

This repository uses a Git submodule for its rust-rapdisnark dependency. You should pull it via:

git submodule init
git submodule update

TODOs

Prover service

• Why is the description of keyless-common/ set to "Aptos Keyless circuit tests" in its Cargo.toml?
• The Cargo.toml description of circuit/ also seem inappropriate
• Redundant OnChainGroth16VerificationKey struct
• Move some shared prover and vk-diff code to keyless-common

Circuit

• Remove public inputs hash and do commit-and-prove
• Pedersen-based keyless addresses and avoid Poseidon hashing, except for Fiat-Shamir maybe
