Smart Contract-Based Decentralized Voting System for Transparent Elections on Ethereum Blockchain

Abstract - This paper presents a secure, transparent and tamper-proof decentralized electronic voting system leveraging Ethereum blockchain and smart contracts. Traditional voting systems are prone to manipulation, centralization risks and accessibility issues. This study proposes a blockchain-based architecture that removes the need for intermediaries, utilizes smart contracts for automating election logic and records votes immutably. The prototype is implemented using Solidity, Truffle Suite, Ganache and MetaMask to demonstrate secure authentication, vote casting and real-time result visualization. The system ensures voter anonymity, prevents double voting and enables auditability through public ledger transparency. The paper concludes with testing results and outlines potential scalability and privacy enhancements. Key Words: Blockchain, Ethereum, Voting System, Smart Contracts, Transparency, e-Voting and dApp
