A secure, transparent, and hybrid voting application that combines the security of the Ethereum blockchain with a user-friendly Web2 authentication layer. This system ensures that while user authentication is handled centrally, all votes are cast and tallied directly on the blockchain, making them immutable and tamper-proof.
- Hybrid Architecture: Web2 login (MySQL + JWT) for access control combined with Web3 (Ethereum) for voting.
- Role-Based Access:
- Admin Portal: Create elections, define timeframes, and add candidates.
- Voter Portal: View active elections and cast votes securely.
- Immutable Voting: Votes are recorded as transactions on the Ethereum blockchain via Smart Contracts.
- Real-Time Tallying: Live election results fetched directly from the blockchain.
- Secure Authentication: JSON Web Tokens (JWT) used for session management.
- Double-Vote Prevention: Smart contracts ensure each wallet address can vote only once per election.
- Solidity: Smart Contract development.
- Truffle: Development framework for compiling and deploying contracts.
- Ganache: Local blockchain for testing.
- Web3.js: Library for interacting with the blockchain from the frontend.
- Python (FastAPI): REST API for user login and JWT generation.
- MySQL: Relational database for storing user credentials and roles.
- Node.js (Express): Web server to serve static files and handle routing.
- HTML/CSS/JS: Responsive user interface.
- Metamask: Browser extension for wallet management and transaction signing.
