P5 - Python frontend interface for Ethereum Layer 2 Blockchain

Adding data to the blockchain with the Clientside callback in Dash. In this tutorial series we'll create the front end interface in Python using Dash. We will use a pre-built smart contract, written in solidity, to create and deploy a decentralized application on top of it. There will be a little bit of javascript used for inserting data into the blockchain, but most of the app will be in Python.
