Build a Blockchain with Javascript

In this class we will learn how to write your own Blockchain with JavaScript. In this video I'll show you what is behind a blockchain by using simple code. It's not a complete implementation, but enough to understand how blockchains work and how they guarantee that blocks can never be changed.
After creating our blockchain we'll try and tamper with it. This will demonstrate a blockchains ability to detect fraud.
