An Application for Tracking Organ Donation in Hospitals Using Blockchain

Abstract

Organ donation and transplantation systems are complex, sensitive, and often hindered by inefficiencies, lack of transparency, and data integrity issues. Traditional centralized systems struggle to manage consent, allocation, and tracking of organs in a secure and auditable manner. This paper proposes a blockchain-based application using a private Ethereum network to streamline and decentralize the organ donation process across hospitals. The system employs smart contracts and algorithm-driven matching to ensure secure donor registration, real-time tracking of organs, transparent allocation based on medical criteria, and immutable audit trails. Six core algorithms are implemented to manage consent, priority allocation, organ transport, and compliance verification. The experimental results demonstrate that the proposed system enhances privacy, accountability, and operational efficiency compared to existing methods. This solution not only reduces the risk of organ misuse and illegal trade but also builds trust among stakeholders, laying a strong foundation for ethical and technologically advanced organ donation management.
