/**
|
||||
* BLS (Barreto-Lynn-Scott) family of pairing-friendly curves.
|
||||
* Implements BLS (Boneh-Lynn-Shacham) signatures.
|
||||
* Consists of two curves: G1 and G2:
|
||||
* - G1 is a subgroup of (x, y) E(Fq) over y² = x³ + 4.
|
||||
* - G2 is a subgroup of ((x₁, x₂+i), (y₁, y₂+i)) E(Fq²) over y² = x³ + 4(1 + i) where i is √-1
|
||||
* - Gt, created by bilinear (ate) pairing e(G1, G2), consists of p-th roots of unity in
|
||||
* Fq^k where k is embedding degree. Only degree 12 is currently supported, 24 is not.
|
||||
* Pairing is used to aggregate and verify signatures.
|
||||
* We are using Fp for private keys (shorter) and Fp₂ for signatures (longer).
|
||||
* Some projects may prefer to swap this relation, it is not supported for now.

* `k256.Point.BASE.add(p256.Point.BASE)`
|
||||
* * For this purpose we want to use `instanceof` operator, which is fast and works during runtime
|
||||
* * Different calls of `curve()` would return different classes -
|
||||
* `curve(params) !== curve(params)`: if somebody decided to monkey-patch their curve,
|
||||
* it won't affect others
|
||||
*
|
||||
* TypeScript can't infer types for classes created inside a function. Classes is one instance of nominative types in TypeScript and interfaces only check for shape, so it's hard to create unique type for every function call.
|
||||
*
|
||||
* We can use generic types via some param, like curve opts, but that would:
|
||||
* 1. Enable interaction between `curve(params)` and `curve(params)` (curves of same params)
|
||||
* which is hard to debug.
|
||||
* 2. Params can be generic and we can't enforce them to be constant value:
|
||||
* if somebody creates curve from non-constant params,
|
||||
* it would be allowed to interact with other curves with non-constant params
|
||||
*

||||
