Application of Blockchain in Healthcare

Blockchain appears to be the way of the future in today’s technological age. Blockchain technology has recently proven itself worthy of praise by facilitating cryptocurrency financial transactions. Despite being widely researched, there have recently been growing worries about the privacy and security of patient data because of the use of a centralized system to handle patient data. The General Data Protection Regulation (GDPR) grants the subject the right to know where and how his or her personal data is stored, as well as who is privy to it and to what extent. Blockchain has been shown in numerous studies to be capable of supporting the safe and secure recording of patient data in the health-care system. This paper summarizes recent research into how blockchain technology can be successfully implemented in the healthcare field. In our assessment of such publications, we discovered that the majority of blockchain applications are limited when only briefly examined. The products are only used by a small number of people. Perhaps this is due to the fact that healthcare blockchain applications have more demanding authentication, interoperability, and record sharing requirements. However, the quality of the products is constantly improving.
