This document outlines the steps to run a blockchain project using Python and Django. It describes setting up the development environment with Python 3.7 and installing Django using pip. The project contains 4 modules: a Peer module to add peer details, a Block module to add peers to blocks, a Transaction module for peers to transfer coins, and a Chain module that validates transactions and adds them to the chain if the hash is validated. It provides instructions on using the web interface to add peers, view peers and blocks, perform transactions between peers, and view the full transaction chain. The blockchain code uses functions to validate all transactions by comparing old and new hash codes.
