BLOCKCHAIN-BASED SECURE E-VOTING SYSTEM WITH PRIVACY-PRESERVING AND SCALABLE ARCHITECTURE

Abstract

Elections may be expedited, simplified, and enhanced through electronic voting. They are not frequently employed as a result of security, transparency, scalability, and voter confidentiality concerns. Our blockchain-based electronic voting system is impermeable, visible, and privacy-protective due to the use of advanced cryptographic algorithms and a permissioned distributed ledger. A permissioned blockchain that employs an expedited consensus method enhances throughput and minimizes latency during critical elections. Voter registration, voting, and tabulation are automated through the use of smart contracts. This mitigates centralization and manipulation. Privacy is safeguarded through encryption, decentralized identity (DID) frameworks, and verified methods. Comprehensive verification is facilitated by the protection of voter anonymity. In a hybrid architecture, scalability is enhanced and computational power is reduced through off-chain storage and on-chain validation. The proposed system is capable of withstanding unauthorized access, data manipulation, and duplicate voting, as evidenced by a comprehensive security and performance analysis. Furthermore, it surpasses voting systems that are founded on blockchain technology. The findings indicate that the secure digital election technology is both scalable and viable, thereby facilitating the implementation of transparent and dependable voting systems.
