Electronic health records (EHR) and patient health records are an Internet-based health application which is sharable to authorized stakeholders such as doctors, specialist, and patients. One of the important record is blood and sharing the blood record in secured manner is a challenging issue. Blockchain-based blood bank system can resolve the need for individuals to access, trace, manage, share their health and blood-related information, which is immutable. The blockchain-based system provides a secured environment which acts as communication hub between donors, doctors, testing laboratories, and recipients or patients. This work proposes the design of a blockchain-based solution for the blood bank system. Information related to the blood is communicated securely to the intended users from the blood bank. Additionally, the traceability feature included in the proposed system monitors detailed information of blood transfer from excess stock to the nearest place. The system model is designed, implemented and validated using solidity language platform.
