P2P stands for Peer-To-Peer. In plain English, a P2P network is created when two or more computers are connected and share resources without going through a separate server computer. All computers in a P2P network have the equal privilege. There is no need for central coordination. A computer in a P2P network is usually called a node. One of the most famous P2P systems is Napster, a file sharing system.

The blockchain is a decentralized, distributed database. The data in a Blockchain will reside at every single node of the Blockchain network. There are always computers join the network and computers left the network, so we can’t rely on a particular computer for storing data and exchanging data. Therefore, a P2P network is the best option for building a Blockchain network.

There are a lot of ways to implement a P2P network, for demo purposes, I decided to use a high-level protocol, WebSocket. WebSocket provides full-duplex communication channels over a single TCP connection. It is located at layer 7 in the OSI model. The WebSocket handshake uses the HTTP Upgrade header to change from the HTTP protocol to the WebSocket protocol.
