Abstract
Blockchain technology is the technology of the twenty-first century. Web
3.0 is the name given to the next digital revolution. It was first developed to provide a
secure payment mechanism, but it was later adapted and utilized in various industries.
Healthcare is one of the domains where this technology has been deployed in the last
few years and has yielded considerable results. The fast adoption of digital technology
in the clinical sector has led to the construction of massive health records. As a result of
this growth, there are never-before-seen requirements for clinical information security
throughout usage and exchange. This adoption of the blockchain method as a
reasonable and effective data storage and handling platform is opening up new
opportunities in healthcare for tackling key data privacy, security, and integrity issues.
Patients and healthcare providers have difficulty accessing, storing, integrating, and
transmitting health information. Individuals are likely to access and control their
medical information from everywhere on the planet, process and report their clinical
findings, grant permissions, and even securely exchange that data with certain medical
professionals. Straightforward health information access and an even more complete
digital information architecture might help the medical industry better prepare for
public health threats like COVID-19. We will examine several of the numerous ways
that blockchain methodology has been employed in the clinical area, as well as its
prospective scopes and possibilities for a better tomorrow, in this research.
