navio-blsct/dist/keys/doublePublicKey.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.

/** The unique source from which an address is derived.
 * A `DoublePublicKey` is a pair of `PublicKey`s that can be used to derive an address.
 *
 * Instantiating a `DoublePublicKey` object without a parameter returns a `DoublePublicKey` consisting of two randomly generated `PublicKey`s.
 *
 * Examples:
 * ```ts
 * const { DoublePublicKey, PublicKey } = require('navio-blsct')
 * const dpk = new DoublePublicKey()
 * const pk1 = PublicKey.random()
 * const pk2 = PublicKey.random()
 * const dpk2 = DoublePublicKey.from_public_keys(pk1, pk2)
 * const vk = Scalar.random()
 * const spendingPk = PublicKey.random()
 * const dpk3 = DoublePublicKey.fromKeysAndAcctAddr(vk, spendingPk, 1, 2)
 * const ser = dpk3.serialize()
 * const deser = DoublePublicKey.deserialize(ser)
 * deser.serialize() == ser
 * ```
