How To

Explorer

Navigate in a terminal to /Explorer and type python app.py to start the Flask server on localhost:5000.

Nodes

Navigate to /Node and type python node.py 8000 to start a node on localhost:8000. The port number can be changed but the initial Node has to be on 8000!

Why

The nodes represent and endpoint/app for mining and utilising the blockchain. The explorer is simply there to have a look at what is currently on the blockchain.
