In this chapter, we introduce blockchain as an effective system to manage patient records and track medical drugs along the pharmaceutical supply chain. Blockchain technology, in short, is a digitalized and decentralized ledger that could be made public or private depending on the user where transactional data is being recorded and unable to be tampered with in the system. Blockchain offers a robust tracking solution for healthcare patients and medical drugs. The application of blockchain technology to healthcare is in its infancy, and there are still some challenges in deploying it in the healthcare sector.
