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.
Curve information:
- Base field: q = 52435875175126190479447740508185965837690552500527637822603658699938581184513
