This library implements the Bendersnatch curve, 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 Simon Masson from
Anoma, and Antonio Sanso from Ethereum Foundation, and is also known as [bandersnatch](https://ethresear.ch/t/introducing-bandersnatch-a-fast-elliptic-curve-built-over-the-bls12-381-scalar-field/9957).
See [here](https://github.com/asanso/Bandersnatch/blob/main/README.md) for the specification of the curve.
There was also a Python implementation [here](https://github.com/asanso/Bandersnatch/).
