Coconut

=======

Coconut [[paper](https://arxiv.org/abs/1802.07344)] is a distributed cryptographic signing scheme providing a high degree of privacy for its users. You can find an overview of how to use it in the [Coconut section](https://nymtech.net/docs/overview/private-access-control/) of the Nym documentation. 

A [simple explanation](https://constructiveproof.com/posts/2020-03-24-nym-credentials-overview/) is also available in blog form. 

This repo contains Go and Rust implementations of Coconut. 

Note: Currently the libraries are **not** interoperable - different methods of curve hash are being used.

[comment]: <> (They are interoperable - credentials created and re-randomized in Rust can be verified in Go, and vice versa.)

Running the Rust CLI demo

================

First, install Rust for your operating system. Instructions can be found at the [Rust](https://rust-lang.org) website.

Once Rust is installed:

```

git clone https://github.com/nymtech/coconut.git

cd coconut/cli-demo-rs

cargo run 

```

Follow the prompts to demonstrate Coconut functionality.

We suggest: 

4 issuing authorities

Threshold of 3

2 public attributes

1 private attribute

Running the Webassembly demo

==================

Instructions are in the [webassembly-demo README](wasm-demo)
