This is a halo2 backend for the Noir Programming Language
WARNING: This crate is experimental and under development. Expect bugs and unoptimized circuits.
This crate will not be possible without
- barretenberg backend
- halo2-zcash
- halo2-pse
- halo2-axiom
- the gadets and educational resources provided by the halo2 community see awesome-halo2
git clone https://github.com/Ethan-000/noir --branch demo-0.1.2
cd noir
To install pse's halo2 as backend:
cargo install --path crates/nargo_cli --locked --features pse_halo2_backend --no-default-features
To install axioms's halo2 as backend:
cargo install --path crates/nargo_cli --locked --features axiom_halo2_backend --no-default-features
Notice that axiom's fork is built on pse's fork and should be similar.
cd to the crates/noir_halo2_backend_common/test_programs folder of this crate and choose one of the tests/examples eg. 3_add
cd 3_add
to generate proof run
