Implementation of Trust-based Blood Donation and Transfusion System using Blockchain Technology

The current solutions for managing blood are based on a centralised database management system. Even though it serves better than the manual system that was in place previously, several problems still exist, including the inability to trace blood components from their collection until consumption, lack of blood quality control and the potential for transfusion-related diseases like HIV, Hepatitis B and C, Syphilis and Malaria. Blood is scarce in some areas, while blood is wasted in other areas due to its short shelf life. The traceability and immutability of the data kept in the chain make Blockchain Technology (BCT) appropriate for blood donation and transfusion management. Numerous real-time cryptocurrency and non-crypto currency applications now use BCT. Hyperledger Fabric, a permissioned BC platform, is employed in constructing a block-chain-based Blood Donation and Transfusion Management System (BDTMS) in this research. The system users may quickly trace the blood with the established model. In addition, smart contracts have been developed to verify the accuracy of the blood data, so only the legitimate data may be kept in the blockchain. The implemented system's performance has been tested using real-time blood data obtained from a blood bank.
