Lioncore

Infrastructure to build Lioncoin and blockchain-based applications for the next generation of financial technology.

Note: If you're looking for the Lioncore Library please see: https://github.com/lioncoin-project/lioncore-lib

Getting Started

Before you begin you'll need to have Node.js v4 or v0.12 installed. There are several options for installation. One method is to use nvm to easily switch between different versions, or download directly from Node.js.

npm install -g lioncore

Spin up a full node and join the network:

npm install -g lioncore
lioncored

You can then view the Insight block explorer at the default location: http://localhost:3001/insight, and your configuration file will be found in your home directory at ~/.lioncore.

Create a transaction:

var lioncore = require('lioncore');
var transaction = new lioncore.Transaction();
var transaction.from(unspent).to(address, amount);
transaction.sign(privateKey);
