Abstract

This survey provides a state-of-the-art survey of the applications of blockchain technology in the healthcare industry with a few case studies. It aims to explore the significance of blockchain technology in healthcare and its potential to enhance healthcare services in the context of federated blockchain. The paper covers background information on healthcare technology and the benefits, challenges, and limitations of using blockchain technology in healthcare. In this regard, we proposed provenance-based architecture, Hyperledger Fabric-based architecture, and integrated architecture, which contains Aadhar verification and patient history features in the context of India. Overall, the paper demonstrates that blockchain technology has the potential to improve the healthcare industry significantly, but more research and development are required to overcome the challenges and limitations.
