navio-blsct/dist/signature.d.ts

TypeScript bindings for the `libblsct` library used by the [Navio](https://nav.io/) blockchain to construct confidential transactions based on the BLS12-381 curve.

 * ```ts

 * sig.verify(pk, 'navio')
 * const ser = sig.serialize()
 * const deser = Signature.deserialize(ser)
 * ser === deser.serialize() // true
