# bellman [![Crates.io](https://img.shields.io/crates/v/bellman.svg)](https://crates.io/crates/bellman) #
This is a research project being built for [Zcash](https://z.cash/).
`bellman` is a crate for building zk-SNARK circuits. It provides circuit traits
and primitive structures, as well as basic gadget implementations such as
booleans and number abstractions.
## Roadmap
`bellman` is being refactored into a generic proving library. Currently it is
pairing-specific, and different types of proving systems need to be implemented
as sub-modules. After the refactor, `bellman` will be generic using the `ff` and
`group` crates, while specific proving systems will be separate crates that pull
in the dependencies they require.

# librustzcash
This repository contains librustzcash, a static library for Zcash code assets written in Rust.
`librustzcash` is an FFI library crate that exposes the Zcash Rust components to
the `zcashd` full node.
The FFI API does not have any stability guarantees, and will change as required
by `zcashd`.
