> Implementation of basic functions of a binary Merkle tree. This module handles binary trees like this (v = value, n = node, r = nonce): ```ts n0 | --------- | | n1 n2 | | |-----| | v0 r0 | --------- | | n3 n4 | | |-----| | v1 r1 r2 ``` A user defines an array of values where these values are hashed into an `imprint`, which is a Merkle root tree hash. A user can expose selected values to a third-party by providing the evidence file which includes a recipe of `values` and `nodes`. This file holds enough information for a third-party to recreate the imprint. ```js import { sha } from '@0xcert/utils'; import { Merkle } from '@0xcert/merkle'; const merkle = new Merkle({ hasher: (v, p, k) => sha(256, v), noncer: (p) => Math.random().toString(36).substring(7), }); const values = ['A', 'B', 'C', 'D', 'E']; const expose = [2, 3]; const fullRecipe = await merkle.notarize(values); const minRecipe = await merkle.disclose(fullRecipe, expose); const imprint = await merkle.imprint(minRecipe); ``` The [0xcert Framework](https://docs.0xcert.org) is a free and open-source JavaScript library that provides tools for building powerful decentralized applications. Please refer to the [official documentation](https://docs.0xcert.org) for more details. This module is one of the bricks of the [0xcert Framework](https://docs.0xcert.org). It's written with [TypeScript](https://www.typescriptlang.org) and it's actively maintained. The source code is available on [GitHub](https://github.com/0xcert/framework) where you can also find our [issue tracker](https://github.com/0xcert/framework/issues).
