This repository has been archived. In this library, I rewrote the API and codebase for Bellman. I think it is easier to read and review but it has fallen far behind master: do not use it for anything! If you like, some people have found it easier to understand the original protocol by reading the code in this repository.
We have publicly forked the Zcash library beacuase we are refactoring bellman. In its current state, the library is difficult to understand if you are not familiar with both the original Groth16 paper, as well as the work by the Zcash and Sonic team on extending the capabilities of the implementation. One consequence of this is that vetting the library for bugs and errors is considerably harder, because we are attempting to understand 200+ line functions with ambiguous names deeply connected to the academic works. Maintaining the work is also somewhat harder, because the original team is required to understand particular design decisions.
Feel free to raise issues if you have an improvement (however small) or notice that we have made an error, especially because there are parts of the library where we have had to make assumptions because the original work has elided or not documented components of the design.
This repository contains a fork of a (work-in-progress) set of Rust crates for working with Zcash.
These libraries are currently under development and have not been fully-reviewed.
