Traditional organ donation management systems rely on centralized databases, which are vulnerable to data manipulation, lack transparency, and may suffer from trust deficits among stakeholders. This paper proposes a Blockchainbased Secure and Transparent Organ Donation Management System that ensures data integrity, traceability, and fairness in organ allocation. The system leverages smart contracts for automated matching and allocation, role-based access control for privacy preservation, and cryptographic hashing for immutable record maintenance. A decentralized ledger records donor registration, medical compatibility checks, waiting lists, and transplant confirmations. Experimental evaluation demonstrates improved transparency, reduced risk of data tampering, enhanced traceability, and secure multi-stakeholder coordination. The proposed system enhances trust among hospitals, organ banks, government agencies, and recipients while maintaining regulatory compliance.
