Abstract - Blockchain technology has emerged as a practical solution for secure and transparent digital voting systems. Traditional voting systems, especially online voting methods, often face security risks like hacking, tampering, and vote manipulation. Maintaining voter anonymity and ensuring data integrity are also major challenges. Blockchain, with its distributed and unchanged able ledger, offers solutions by providing a secure and decentralized way to record votes. This paper looks at the structure, implementation, and bene f its of a blockchain-based online voting system that uses blockchain’s security features to improve the voting process. By using cryptographic methods and decentralized data storage, the system boosts transparency, lowers fraud risks, and makes sure votes are unchangeable. The proposed system includes steps for voter registration, vote casting, and result verification, all secured by smart contracts. Experimental results show that blockchain can keep voter anonymity, resist tampering, and provide a traceable voting record. The study also discusses challenges in scalability, timing, and following guidelines, offering ideas for improvements and future efforts. Overall, the research suggests that blockchain-based voting could change electoral pro cases, providing a reliable digital voting option that supports democratic values.
