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-service/. Its README contains instructions for building and running tests.
3. A circom unit testing framework in circuit/. Its README contains instructions for running the circuit unit tests.
4. Some shared rust code in keyless-common/.
5. A VK diff tool in vk-diff (see its README for details).

To setup your environment for both the prover service and the circuit, run the following command:

./scripts/task.sh setup-dev-environment

Optionally, it is possible to install a precommit hook that checks whether the circuit compiles before committing. To do this, run the following command:

./scripts/task.sh misc install-circom-precommit-hook

For more information on the actions defined for this repo, see the scripts README.

• Why is the description of keyless-common/ set to "Aptos Keyless circuit tests" in its Cargo.toml?
  • Changed description to "Shared code that is used both by the prover service and circuit unit tests."
• The Cargo.toml description of circuit/ also seem inappropriate
  • Changed description to "The Aptos Keyless circuit (circom) and unit tests (rust)."
• Redundant OnChainGroth16VerificationKey struct
• Move some shared prover and vk-diff code to keyless-common

• Remove public inputs hash and do commit-and-prove
• Pedersen-based keyless addresses and avoid Poseidon hashing, except for Fiat-Shamir maybe
• The circuit is in the circuit directory, but its Cargo.toml sets the crate name to be aptos-keyless-circuit. Might be less confusing to have the directory name agree with the crate name?
