A proposal for a Blockchain based applicationto trace Healthcare Supply Chain across Sri Lanka

Healthcare Supply Chain (HSC) traceability involves a wide range of stakeholders, including raw material suppliers, manufacturers, distributors, regulatory authorities, pharmacies, hospitals, and patients. For a HSC system that is unalterable, trustworthy, accountable, and transparent, blockchain-based drug tracking offers a promising solution. In this piece, we examine the challenges associated in tracking products within the HSC and then go on to discuss how blockchain technology may be used to effectively combat counterfeit pharmaceuticals by providing a provenance, track, and trace solution. To fulfill the fundamental requirements for drug tracing, such as confidentiality, honesty, openness, safety, authentication, and scalability, we introduce two different blockchain-based decentralized architectures: Hyperledger Fabric and Besu. We highlight many open research issues about blockchain technology's potential for use in medication tracking and provide answers to those questions. Research and Development motivation toward the Health Informatics Sector now has a useful guide for creating and implementing a comprehensive blockchain-based solution for the healthcare industry in Sri Lanka. Through this paper we discuss how blockchain can improve the traceability in the healthcare supply chain sector.
