VoteChain – Blockchain Based E-Voting System

Abstract

The integrity of electoral systems is fundamental to democratic governance, yet existing paper-based and centralized electronic voting mechanisms face persistent challenges related to security, transparency, scalability, and public trust. This paper proposes VoteChain, a blockchain-based electronic voting framework that leverages decentralization, immutability, and cryptographic security to ensure trustworthy elections. Votes are recorded as encrypted transactions on a distributed ledger, while smart contracts automate voter verification, vote validation, and real-time tallying, minimizing human intervention. The framework preserves voter anonymity, enforces vote uniqueness, and enables end-to-end verifiability without exposing sensitive data. VoteChain’s modular architecture supports scalable deployment across institutional and public elections.
