ElectraGuard:A Blockchain-Based Opinion Polling System for Tamper-Proof Surveys

Abstract

In our Society public opinion surveys are necessary for understanding societal viewpoints, but the conventional polling platforms are at a high risk of forgery, data breaches and manipulation. To ensure the reliability and integrity of polling outcomes, there is a growing need for secure and transparent mechanisms [1]. This paper presents ElectraGuard, a blockchain-based online polling platform designed to deliver trustworthy, tamper-resistant, and user-friendly opinion polling. Built on the Ethereum blockchain using smart contracts, ElectraGuard ensures decentralised execution, voter anonymity, and one-response-per-participant integrity [2]. The system leverages cryptographic hashing and distributed ledger technology to record each submission immutably, preventing result falsification or post-hoc modification. Supporting multiple categories of institutional and organizational polls, the platform features a web-based interface that enables secure participation and real-time result visualization. Testing shows that ElectraGuard greatly improves the security, ability to check results, and trustworthiness of online polling, providing a strong base for clear and checkable digital surveys.
