Abstract - Organ donation plays a critical role in saving lives, yet traditional systems often struggle with issues such as lack of transparency, data tampering risks, and inefficient donor-recipient matching. This paper presents a blockchain-based decentralized application (DApp) designed to enhance the security, transparency, and efficiency of organ donation and transplantation processes. By leveraging smart contracts on a private Ethereum blockchain, the system automates key operations including donor registration, organ availability tracking, and recipient prioritization, all while maintaining the integrity of sensitive medical records. The use of a decentralized architecture ensures that data is tamper-proof and accessible only to authorized entities such as hospitals and regulatory bodies. A queue-based organ allocation algorithm is implemented to match recipients based on medical urgency and compatibility factors like blood type and organ requirements. The system is built using React.js for the frontend and Solidity for smart contract development, with Truffle and Ganache supporting local blockchain deployment. This approach not only secures sensitive health data but also improves the fairness and responsiveness of organ distribution.
