Getting Started

To set up the project and install all dependencies, run the following command:

npm install -D

Explore the available scripts in the package.json file. Some key scripts include:

  • For the entire process from circuit compilation to verification with WASM:

    npm run circom:compile:wasm:witness:setup:prove:verify

  • Generate a verifier contract using:

    npm run circom:verifier

  • Generate calldata for a verifier contract with:

    npm run circom:calldata

Testing

Execute the tests using:

npm run test

Note

The implementation in both Circom and Noir is identical, with the exception of how commitments are calculated.

For Circom, the commitment is influenced by the number of registers (k). This is represented as MiMCSponge([address, msgHash]), where msgHash is of a length that matches the value of k specified in the parameters. On the other hand, in Noir, the commitment calculation is mimc_sponge([address, msg_hash]), with msg_hash consisting of 32 elements, each one byte in length.
