Blockchain Voting Platform using React, Node.js & Ethereum

The Blockchain Voting Platform is a decentralized, web-based solution designed to ensure secure, transparent, and tamper-proof digital elections for institutions, developer communities, and governance applications. Leveraging React.js for the frontend, Node.js and Express for the backend, and Ethereum blockchain smart contracts coded in Solidity, the system offers end-to-end election lifecycle management. Voters register securely, authenticate with MetaMask, and cast votes that are permanently recorded on the Ethereum blockchain using smart contracts. Real-time vote counts and election analytics are displayed using interactive dashboards and charts (Recharts), with WebSocket technology supporting instantaneous updates. The admin panel empowers authorized personnel to initiate new elections, manage candidates, monitor live ballots, and export data as Excel reports. Database operations are managed through Drizzle ORM over PostgreSQL, ensuring high reliability and data integrity. The stack incorporates Vite for rapid development, Ethers.js for blockchain connectivity, TypeScript for strong typing, and robust session handling for secure operations. The platform is ideal for modern e-governance, campus elections, society polls, and Web3 learning labs, with future scope for blockchain integration into national voting, advanced cryptographic voter privacy, and cross-chain platform support.​
