halo2-axiom
growingv0.5.2
Fast PLONK-based zero-knowledge proving system. This is a fork of <https://github.com/privacy-scaling-explorations/halo2>, which is itself a fork of ZCash's "halo2_proofs" crate. This fork uses the KZG polynomial commitment scheme for the proving backend, which requires a one-time universal trusted setup. Publishing this crate for better versioning in Axiom's production usage.
