In general terms we kinda think we understand what blockchain is, right? It’s a distributed database with very secure encryption making it unchangeable and at the same time publicly visible and annonymous. Sounds good but what does that mean in real terms? If you’re still curious how all this comes together, here’s a demo created by Sean Han @seanjameshan · Developer & Designer, who exlpains, “Blockchain Demo is my attempt at demystifying the technology behind cryptocurrencies. It has a living blockchain, a peer-to-peer network, and a user tour.” You can walk through the 28 steps that describe what blockchain is and how it is made. By the way, this it NOT a crypto-currency demo. Remember that blockchain has lots of uses beyond exchanging money.
