@crpdo/merkle is a dynamic, in-memory implementation of a Merkle Tree in JS. It's part of the larger crpdo project, a JavaScript-based library for cryptography. This module emphasizes the practical, real-world application of Merkle Trees, providing features like checkpointing and the generation of Merkle proofs.

Features

  • Dynamic Tree Management: Streamlined processes for creating Merkle Trees and adding leaves, facilitating quick and responsive tree modifications.
  • Merkle Proof Generation and Verification: Generate Merkle proofs and verify them, ensuring data integrity and promoting secure data interactions.
  • Checkpointing: Preserve the state at various points in time, enabling users to revert to previous tree states as needed.
  • Immutable Design: Ensuring that once data is recorded, it cannot be altered without detection, contributing to the overall security and reliability of data operations.

Installation

npm install @crpdo/merkle

Usage

Import the Merkle class and create a new merkle tree:

const Merkle = require('@crpdo/merkle')

const tree = new Merkle()

Here is a brief example of how to use the @crpdo/merkle module:

const Merkle = require('@crpdo/merkle')

// Initialize a new Merkle Tree
const tree = new Merkle()

// Add leaves to the tree
tree.addLeaves(['data1', 'data2', 'data3'])

// Generate a Merkle proof
const proof = tree.getProof('data1')

// Verify the proof
const isValid = tree.verifyProof(proof, 'data1')
