Electronic voting systems have been increasingly adopted to improve the efficiency and accessibility of modern elections. However, traditional electronic voting platforms often suffer from several limitations, including security vulnerabilities, lack of transparency, centralized control, and potential risks of vote tampering. These challenges can undermine public trust in electoral processes and highlight the need for more secure and transparent voting mechanisms. Recent advancements in Block chain Technology provide a promising solution for addressing these issues by enabling decentralized, tamper-resistant, and verifiable systems. This study proposes a blockchain-based secure electronic voting framework designed to ensure data integrity, voter privacy, and transparent vote counting. The proposed system utilizes a distributed ledger to record votes as immutable transactions, making it nearly impossible for unauthorized parties to alter or manipulate the stored data. Each vote is encrypted using modern Cryptography techniques before being added to the block chain network, ensuring voter anonymity while maintaining the authenticity of the election process. In addition, smart contracts automate the voting procedures, including voter authentication, vote casting, and result tabulation, thereby reducing human intervention and potential errors. The system architecture integrates a voter registration module, authentication mechanism, block chain network, and secure voting interface. Through the use of decentralized consensus mechanisms, the proposed approach eliminates reliance on a central authority and enables transparent verification of election results by authorized participants. Performance evaluation of the system demonstrates improved security, reliability, and transparency compared with conventional Electronic Voting approaches. Furthermore, the system provides an auditable and tamper-proof record of all voting transactions, ensuring accountability throughout the electoral process.
