Blockchain in Python

This project contains multiple pieces to create a functional of blockchain (although not production ready)

It also suport wallet as an escrow and leverages the events triggered from the blockchain.

overview of the project

• Blockchain.py file: This file is the main class used to define functions such as transaction, wallet, proof of work, mining hashing, nonce and generating the genesis.
• block.py file: This file is defined as the class of block synchronisation.
• Transcation.py file: This file is defined the class of transaction which can be added to a block in the blockchain.
• Wallet.py file: This file is defined the class of the wallet conception used to interact with the blockchain. Creates, loads and holds private and public keys. Manages transaction signing and verification.
• Node.py file: This file is the flask app class that combined the others class to run.
• OLD-node.py file: This file is run two diffrent blockchain for synchronisation.
• ui file content the user interface for (network.html and node.html).
• Utility file, this file contents the support of the verfication and imporovment.

Requirements

• python 3 and above
• pip install Flask
• pip install crypto
• pip install Flask-Cors

Build & Compile

• Python3 node.py
• Running on all addresses (0.0.0.0)

• Running on http://127.0.0.1:5000 new node
• Running on http://192.168.1.8:5000 old node

Front-end

• UI , will run the flask on network.html by calling the class of the node.py.

Back-end

• Node.py class will calling the class of the blockchain.py, old-node.py, Transcation.py, block.py and wallet.py.
