lethean-util

CryptoNote node utility for Lethean — address generation, validation, and block/transaction processing.

This is Lethean's equivalent of cryptoforknote-util. It's a C++ native Node.js addon that links against the Lethean blockchain source tree.

Install

npm install
# Requires: cmake, g++, libboost-all-dev
# The native addon links against ../blockchain/src/ via the Lethean symlink

Usage

var cn = require('lethean-util');

// Validate address
var decoded = cn.address_decode(Buffer.from('iTHNUNiuu3VP...'));

// Get block hash
var hash = cn.get_pow_hash(blockBlob);

// Convert block blob
var converted = cn.convert_blob(blockBlob);
