This library implements a twisted Edwards curve whose base field is the
scalar field of the curve BLS12-377. This allows defining cryptographic
primitives that use elliptic curves over the scalar field of the latter
curve. This curve was generated as part of the paper [\[BCGMMW20, “Zexe”\]](https://eprint.iacr.org/2018/962).
Curve information:
* Base field: q = 8444461749428370424248824938781546531375899335154063827935233455917409239041
* Scalar field: r = 2111115437357092606062206234695386632838870926408408195193685246394721360383
* Valuation(q - 1, 2) = 47
* Valuation(r - 1, 2) = 1
* Curve equation: ax^2 + y^2 =1 + dx^2y^2, where
* a = -1
* d = 3021
