Blockchains are hard to understand, so let’s visualize their inner workings by building a front-end application in Angular. I’ll show you how to visualize blocks on the chain and the transactions inside them. We’ll also make a UI to create new transactions and to mine new blocks.
All of this is based on the Javascript blockchain implementation that we made in the previous 4 parts: SavjeeCoin!
