E-VOTING SYSTEM USING BLOCKCHAIN

Abstract: The credibility of democratic systems relies heavily on the integrity and transparency of electoral processes. Traditional voting mechanisms, including paper ballots and electronic voting machines, suffer from several drawbacks such as centralized control, susceptibility to manipulation, lack of transparency, and delayed result declaration. To address these limitations, this paper proposes a Blockchain-Based E-Voting System that leverages decentralized ledger technology to ensure secure, transparent, and tamper-proof elections. The system utilizes Ethereum-compatible blockchain networks and smart contracts written in Solidity to automate vote validation, storage, and counting. A modern frontend built using React, TypeScript, and Vite provides an intuitive voting interface, while Supabase serves as a cloud backend for authentication, election metadata, and audit logging. Wallet-based voter authentication using MetaMask ensures secure participation and prevents duplicate voting. Experimental evaluation demonstrates that the proposed system significantly improves trust, efficiency, and transparency while reducing operational overhead. The results validate blockchain as a viable solution for secure digital voting systems.
