Electronic voting systems have gained significant attention as a modern alternative to traditional paper-based electoral processes. However, existing electronic voting mechanisms often rely on centralized infrastructures that introduce vulnerabilities such as data tampering, insider manipulation, and lack of audit transparency. These limitations reduce public trust in digital election systems. This paper presents a secure blockchain-based electronic voting platform with cryptographic verification designed to ensure transparency, integrity, voter anonymity, and tamper detection. The proposed system implements a custom lightweight blockchain architecture where all electoral events are recorded as cryptographically linked blocks using SHA-256 hashing. Smart rule enforcement logic ensures voter eligibility verification, prevents duplicate voting, and maintains role based access control. SQLite is integrated for participation tracking while preserving vote anonymity by separating voter identity from ballot payload. The system architecture consists of user interface, logic control layer, blockchain ledger, and persistent storage. Experimental evaluation demonstrates realtime tamper detection, efficient vote recording, secure block validation, and scalability for localized deployments. The results confirm that the proposed model enhances electoral integrity, reduces operational cost, and strengthens trust in digital democratic processes
