This repository contains an implementation of the DPC scheme called VERI-ZEXE [XCZ+22].

This library is released under the GPLv3 License (see License).

WARNING: This is an academic proof-of-concept prototype, and in particular has not received careful code review. This implementation is NOT ready for production use.

Ensure you have the following installed:

• nix
• direnv

Then, run direnv allow at the project root, you should see all dependencies installed.

Feel free to explore src/examples folder for example applications (including simplified Zcash, Zcash, TornadoCash) built on top of the VERI-ZEXE.
