11//! This library implements a twisted Edwards curve whose base field is the
12//! scalar field of the curve BLS12-377.  This allows defining cryptographic
13//! primitives that use elliptic curves over the scalar field of the latter
14//! curve. This curve was generated as part of the paper [\[BCGMMW20, “Zexe”\]](https://eprint.iacr.org/2018/962).
