Plonky2 Verifier

A verifier for plonky2 proofs.

This rust crate provides functionality to deserialize and verify proof, public inputs and verification key.

plonky2-converter

Plonky2 has a certain number of generics for its constraint system, such as used field, hasher etc. Since we are limited by the nature of passing them in zkVerify, we use a custom format of Vk.

For that reason, this crate also provides a binary to convert verification keys into acceptable by zkVerify format.

Furthermore, to bring support for compressed proofs from plonky2, we use a custom format of Proof.

Install:

cargo install --features converter --path .

Usage:

plonky2-converter --help
