WebBLS12-381 is a pairing-friendly curve from the BLS (Barreto, Lynn, Scott) family of curves with embedding degree k=12. BLS12 curves are parameterized by the polynomials p (t) = (t - 1)^2 * (t^4 - t^2 + 1) / 3 + t r (t) = t^4 - t^2 + 1. The curve equation is E: y^2 = x^3 + 4, which admits a a sextic twist E': y^2 = x^3 + 4 (u + 1) where u
