Smart Blockchain-Based Organ Donation System for Secure Donor-Recipient Matching

Although organ donation is a life-saving medical practice that has helped countless individuals, it continues to face major challenges that hinder its effectiveness and fairness. Issues such as lack of transparency, the rise of illegal organ trafficking, and ineffective donor-recipient matching often plague traditional systems. These problems not only lead to unnecessary delays in life- critical situations but also increase the chances of fraudulent practices and significantly reduce public confidence in the donation process. Many potential donors and recipients are left uncertain or excluded due to the inefficiencies and lack of trust in existing systems. To address these pressing concerns, we propose a Blockchain-Based Organ Donation System that leverages the decentralized, transparent, and immutable nature of blockchain technology. This system ensures that all data and transactions are securely recorded and cannot be altered, which enhances accountability and traceability. By integrating smart contracts, the platform can automatically execute and manage donor-recipient matching based on real-time medical data, compatibility, and urgency, ensuring that the allocation process is both fair and tamper-proof. This automation not only eliminates the need for third-party intermediaries but also minimizes the risk of human error and corruption. Additionally, every step in the process—from donor registration and organ availability updates to hospital coordination and recipient assignment—is permanently logged on the blockchain, creating a complete and auditable history. As a result, our approach reduces delays, curbs illegal activities, and fosters a reliable, efficient, and trustworthy ecosystem where patients, families, and healthcare providers can participate with greater confidence and transparency.
