Validity and Integrity check in Supply Chain Management using Blockchain

Abstract

Existing centralized blood supply chain management systems have various drawbacks including lack of information on blood bags, inability to reflect real-time updates in detail and the factor of distrust. Apart from this, our literature survey indicates that the wastage of blood bags is at an all-time high, accredited to the reasons for poor management. We propose a blood collection chain system based on blockchain technology using a distributed ledger structure and transaction execution of the entire process from blood collection till the blood reaches the final stage-hospitals. In this respect, the blockchain technologies offer the possibility to maintain a transparent blood management system, especially since data cannot be counterfeited and tampered with. In addition, the system stores blood contracts between hospitals in the event of emergencies through the transaction and consensus flows. It will also act as a waste management strategy for Blood Bags by splitting and using various contents in the blood such as RBCs, WBCs, Platelets, Plasma to a maximum extent before its expiry.
