Blockchain-Based Voting System Using Zero-Knowledge Authentication

Elections, a democratic process, frequently encounter challenges with traditional voting methods, which are, vote manipulation, transparency deficits, delayed results, and security vulnerabilities. Although Electronic Voting Machines (EVMs) have enhanced efficiency, concerns persist regarding trust and data security. Blockchain technology presents a secure and decentralized server mechanism. Its important features are, transparency, immutability, decentralization, and distributed data storage, it saves voting data from unauthorized access. Our project develops a blockchain-based voting system, implementing in an Android application, leveraging programming technologies to provide secure and safe digital voting. Our system ensures single voter participation through blockchain verification and token- based authentication. This method enhances transparency, boosts security, and avoids vote tampering risks. Our paper further discusses and represents the advantages, limitations, and practical implementation of blockchain technology in electoral systems.
