//! This library implements a twisted Edwards curve whose base field is the
|
|
//! scalar field of the curve BLS12-381. This allows defining cryptographic
|
|
//! primitives that use elliptic curves over the scalar field of the latter
|
|
//! curve. This curve was generated by Sean Bowe, and is also known as [Jubjub](https://github.com/zkcrypto/jubjub).
