A Secure Voting System using Blockchain Technology

Abstract

Secure voting remains a critical challenge in modern democracies due to concerns over transparency, tampering, and voter trust. This paper proposes a blockchain-based voting system designed to enhance the integrity, security, and reliability of electoral processes. By leveraging the decentralized and immutable nature of blockchain technology, the system ensures that each vote is securely recorded and cannot be altered once submitted. Smart contracts are utilized to automate vote validation and counting, eliminating intermediaries and reducing the risk of human error or manipulation. Cryptographic techniques preserve voter anonymity while ensuring authentication, thereby maintaining both privacy and legitimacy. The distributed ledger allows real-time verification and auditing, increasing transparency and public confidence in election outcomes. Performance analysis indicates that the system is scalable and resistant to common cyber threats such as double voting and unauthorized access.
