Verifier implementation​

This pallet implements a verifier for UltraPlonk proofs generated with barretenberg library. This library is part of the Aztec Protocol's suite of cryptographic tools. The Noir compiler generates UltraPlonk zk-SNARK proofs using the barretenberg library as the backend. To generate proofs from Noir code, the nargo tool is used.

  • verify_proof() uses the ultraplonk_verifier crate to verify proofs. The noir-cli tool can be used to transform the proving artifacts generated by barretenberg backend into the format compatible with this pallet.
