A Secure and Transparent Blockchain driven E-Voting System using Smart Contract and IPFS-based Scalability

Abstract

Elections are a cornerstone of democracy. Traditional voting systems such as ballots or Electronic Voting Machines face challenges such as voter fraud, reduced accessibility, security vulnerabilities, lack of transparency, and high operational costs. This paper presents a blockchain-based e-voting system that leverages InterPlanetary File System (IPFS) for secure data storage; smart contract is developed in Solidity and deployed to execute the e-voting system on the Ethereum blockchain network. Twilio-based OTP authentication is integrated to enhance security, while SHA-256 and AES-256 encryption ensure data integrity and confidentiality. The system is designed to minimize transaction costs while optimizing throughput and reducing latency. Preliminary outcomes show a significant reduction in transaction costs, increased scalability with improved system efficiency and resilience against fraudulent activities.
