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.
Curve information:
- Base field: q = 21888242871839275222246405745257275088548364400416034343698204186575808495617
- Scalar field: r = 2736030358979909402780800718157159386076813972158567259200215660948447373041
- Valuation(q - 1, 2) = 28
- Valuation(r - 1, 2) = 4
- Curve equation: ax2 + y2 =1 + dx2y2, where
