Blockchain Based Voting

It is python based implementation of blockchain technology to be used for e-Voting. By considering each vote as transaction to be added to pending_transaction, which is ready to be mined and included in a Block. And then the newly created block is added to the blockchain and broadcast to all the nodes.

Features

The blockchain :

• Possibility of adding multiple nodes to the blockchain
• Proof of Work (PoW)
• Simple conflict resolution between nodes
• Transactions with ecdsa signature verification

The blockchain client has the following features:

• React based Web App
• Here is Client README.md

The blockchain API server for miners

• Block explorer
• Transaction and Block verification & Broadcasting
• Block mining
• p2p communication

Installation

• first clone the repository by typing this code into your terminal.

git clone https://github.com/ephremdeme/voting.git

• simply cd voting and install all the dependencies from requirement.txt by typing this code

pip install -r requirements.txt

• First export Flask api app using export FLASK_APP=api
• on linux terminal run ./run.sh, this will apen a 6 tab terminal for 6 network nodes
• or add each node like python BlockchainAPINode.py 5000
• to add peer node to the blockchain, open postman POST request localhost:5000/register-node/broadcast and send json { "new_node": "http://localhost:5002"}
• to start the blockchain client, go to cd client and execute: python clientGUI.py
• finally open your browser and go to localhost:5000
