Blockchain technology is an emerging technology, and cryptocurrency is the most well-known and successful blockchain application. With the development of the concept of blockchain technology, scientists and practitioners have found the potential of blockchain technology in the supply chain, which has led to much research on blockchain applications. There have been many reviews on the subject, but most of them are specific to particular supply chains and lack specific research on published papers. This paper addresses this research gap by examining, through qualitative analysis, the study finds that blockchain applications are moving in the direction of efficient automation. Appropriate consensus algorithms in different supply chain contexts will improve efficiency while reducing costs, while smart contracts play a huge role in security. Therefore, this paper explored articles related to the topic and explored articles in recent years by keyword combination.

Chronic Disease Medication Data (CDMD) includes a great number of valuable patients’ information collected from smart pillboxes. CDMD sharing in the Chronic Disease Medication Compliance Management System is helpful to improve the medical level and service. Blockchain provides a new way to solve the problems, e.g., privacy security, user control rights, and single point of failure, in data sharing. In this paper, we propose a secure CDMD sharing method in a decentralized way based on blockchain and cryptography technology to realize secure data sharing among entities by a model of ’on-chain deposition to confirm rights, off-chain storage of transmission data’. This method can enable secure sharing of medication administration data between institutions, avoiding the trustless problem caused by data centralization.
