Want to Know How the Blockchain Really Works?
This enterprising young developer built an app to demonstrate. It’s called Blockchain-CLI, which obviously runs on the command line, and uses node.js. If you don’t have node.js installed, you can install it here. You can see a web version of the demo here.
The app shows you what a Block looks like while defining some relevant terms. It also explains what happens when a new Block is mined and how the hash is calculated. It also discusses what a nonce is and why it matters. Pretty valuable info for people getting started with the Blockchain and who have some development knowledge.
