Design and Implementation of a Blockchain-Based Tamper-Proof E-Voting System for Secure...

Objective: To design, develop, and validate a blockchain-based e-voting system that ensures end-to-end vote integrity, transparency, and tamper-resistance for Indian institutional elections.

Problem: Traditional electronic voting systems in India face significant challenges such as vote tampering, lack of transparency, and susceptibility to cyber-attacks, undermining trust in election outcomes for universities, societies, and local bodies.

Solution: This project proposes an engineering solution leveraging blockchain technology to create a decentralized, immutable ledger for e-votes, integrating cryptographic mechanisms for voter authentication, vote privacy, and real-time auditability. The system is designed to be cost-effective and scalable for institutional-scale elections, with a user-friendly web/mobile interface for voters and administrators.

Key Features: The working prototype will include voter registration and authentication using Aadhaar-based OTP verification, a web application for casting votes, a smart contract-based backend on Ethereum (testnet), end-to-end vote encryption, real-time result tabulation, and an admin dashboard for audit trails. The system will be tested against common attack scenarios (double voting, vote modification, insider threats) and its tamper-proof nature will be demonstrated to an examiner panel.

Impact: Adoption of this solution can enhance trust and participation in e-governance and institutional elections across India, setting a benchmark for secure digital voting. Its modular architecture supports scalability for municipal and cooperative elections, aligning with 'Digital India' and e-governance initiatives.
