GcoinJS (gcoinjs-lib)
The pure JavaScript Gcoin library for node.js and browsers. Forked from BitcoinJS.
Installation
npm install gcoinjs-lib
Setup
Node.js
var gcoin = require('gcoinjs-lib')
Examples
For most part of the library, it is the same as bitcoinjs-lib. The main different part from Gcoin to Bitcoin is that Gcoin support multi-color native currency. As a result, when creating new transaction, the addOutput([:address], [:amount], [:color]) method of the TransactionBuilder is different. The color should be added into the last parameter.
