//! 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.)
|

|
|
//! Curve information:
|
|
//! * Base field: q = 258664426012969094010652733694893533536393512754914660539884262666720468348340822774968888139573360124440321458177
