//! This library implements a twisted Edwards curve whose base field is the scalar field of the
|
|
//! curve BN254. This allows defining cryptographic primitives that use elliptic curves over
|
|
//! the scalar field of the latter curve. This curve is also known as [Baby-Jubjub](https://github.com/barryWhiteHat/baby_jubjub).
