Blockchain-Powered E-Voting System: A Secure and Transparent Solution

Abstract

Democratic governance depends fundamentally on the integrity of electoral processes, as public trust in democratic institutions is only as strong as the systems that underpin them. Conventional voting mechanisms whether paper-based or early digital systems face growing scrutiny regarding transparency, auditability, and resistance to manipulation, with high-profile electoral controversies in recent years intensifying calls for more robust and verifiable alternatives. This paper proposes and evaluates a blockchain-powered electronic voting (e-voting) system designed to overcome these longstanding limitations by leveraging the core properties of distributed ledger technology: immutability, decentralization, and cryptographic verifiability. The proposed architecture integrates Ethereum-based smart contracts for automated ballot management, zero-knowledge proof (ZKP) protocols for voter privacy, and a permissioned blockchain layer for regulatory compliance. Together, these components form a cohesive framework that seeks to balance openness with accountability. A comparative evaluation against existing solutions demonstrates measurable improvements in security, voter anonymity, and system auditability. Scalability constraints, regulatory considerations, and real-world deployment challenges are also examined with candor, acknowledging that no technological solution is without friction. The analysis concludes that blockchain-based e-voting represents a technically viable and socially consequential advancement in democratic infrastructure one with the potential to restore and reinforce public confidence in electoral outcomes worldwide.
