BlockChainVotingApp

Ethereum blockchain web application for open voting scenarios (built using Solidity/Truffle/React.JS)

===== Ethereum BlockChain web application for transparent/open voting scenarios (with some degree of optional privacy) =====

• Ethereum key pair based authentication
• Node.JS/Javascript & React.JS frontend
• Smart Contract based backed (using Solidity language)
• Uses Truffle JS & MetaMask for interaction

Required: Node.JS, Ganache (to emulate a local blockchain)

Capabiltiies:

General Use-Case UML Diagram

• Unique vote is enforced
• Encrypted voter authentication data using xsalsa20-poly1305
• Role-based authorization (two roles - voter and election administrator)
• Manual approval of the voters
• Distributed data storage (specific to BlockChain)
• Uses homomorphic encryption (Paillier) to hide the vote count
• All the roles are constrained to follow the mutually estabilished rules of the smart contract
• Backend and frontend validation of the form received data

How to run:

1. Install node modules
2. Start Ganache (CLI or GUI)
3. truffle migrate --reset (to do migration & contract compilation)
4. npm run start (to run the frontend side of the web app)
