//! This library implements the BLS12_377 curve generated in [\[BCGMMW20, “Zexe”\]](https://eprint.iacr.org/2018/962).
|
|
//! The name denotes that it is a Barreto--Lynn--Scott curve of embedding degree
|
|
//! 12, defined over a 377-bit (prime) field. The main feature of this curve is
|
|
//! that both the scalar field and the base field are highly 2-adic.
|
|
//! (This is in contrast to the BLS12_381 curve for which only the scalar field
|
|
//! is highly 2-adic.)
