Many industries, including banking, government, energy, healthcare, etc., have taken an interest in blockchain technology since its inception in the last decade. A comprehensive overview of blockchain's potential uses in the healthcare industry is provided in this article. Research in this field is indeed progressing at a breakneck pace. Thus, we have discovered several cutting-edge applications of blockchain technology, such as medicine supply chain management, electronic medical record sharing, remote patient monitoring, etc. We have also highlighted the shortcomings of the methods that have been examined, and we have wrapped off by delving into some unanswered questions and potential spots for more study. The new Internet of Things applications in Industry 4.0 include blockchain technology, which is immutable, cryptographically secure, distributed ledgers, and a component of decentralized systems. Various entities or parties maintain and distribute exact copies of a succession of transaction lists using this technology. Blockchain technology's capacity to link disparate systems and improve the accuracy of electronic health data, together with a patient-centric approach to healthcare, make it an area with enormous promise.
