Project template to create as simple as possible implementation of a blockchain with Node.js 4+ and JavaScript.

Blockchain Starter Kit

An extremely simple blockchain: a project template to create as simple as possible blockchain system.

Block # 0, also known as Genesis Block, is the first block of its blockchain system. This project provides a minimal blockchain implementation for teaching and research, and you can be provided the simplest way to understand the blockchain.

Features

• Import Genesis Block
• An exetremly simple mining algorithm
• A simple and lightweight REST-style RPC system
• A p2p network system over WebSocket
• There is no proof-of-work implementation

Testing

To start a miner node:

git clone https://github.com/jollen/blockchain-starter-kit.git
cd blockchain-starter-kit
npm install
node index.js

The server will start at localhost:8000 by default. To start another miner node at port 8001 and join an existing network:

export PORT=8001
node node1.js

After index.js has been joined, its successor will become node1.js. To fix the default join node, please open node1.js and modify the join property:

server.start({
    onstart: onstart,
	onmessage: onmessage,
	join: {
		address: 'localhost',
		port: 8000
	}
});
