Crypto Gadgets for Plonky2

A collection of efficient gadgets for Plonky2.

As we're building larger and larger circuits with Plonky2, we want to share some of our work and optimizations, packaged in a single and simple to use library.

Complete Example

See the hello-world example to get started and build your own circuit.

Or run:

cd examples/hello-world
cargo test --release -- --nocapture

(don't forget the --release!)

For more examples you can run the library tests:

cargo test --release -- --nocapture
