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”].

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
