Online Voting System Using Blockchain: A Secure and Transparent Approach

Abstract

Blockchain technology has emerged as a viable solution for secure and transparent digital voting systems. Traditional voting systems, particularly online voting mechanisms, are often vulnerable to security risks such as hacking, tampering, and vote manipulation. Furthermore, maintaining voter anonymity and ensuring data integrity are significant challenges. Blockchain, with its distributed and immutable ledger, offers potential solutions by providing a secure and decentralized approach to recording votes. This paper explores the architecture, implementation, and advantages of a blockchain-based online voting system that leverages the security features of blockchain technology to improve the voting process. By utilizing cryptographic principles and decentralized data storage, the system enhances transparency, reduces fraud risks, and ensures that votes remain immutable. The proposed system includes mechanisms for voter registration, vote casting, and result verification, all of which are secured by smart contracts. Experimental results demonstrate that blockchain can maintain voter anonymity, resist tampering, and provide an auditable voting trail. Additionally, the study discusses challenges in scalability, latency, and regulatory compliance, offering insights into potential improvements and future work. Overall, the research indicates that blockchain based voting has the potential to transform electoral processes, providing a trusted digital voting alternative that aligns with democratic principles.
