BLOCKCHAIN APPLICATIONS FOR COVID-19– A SURVEY

ABSTRACT

The COVID-19 has changed the way technology has been perceived and adapted. It has revealed the potential of technology in overcoming the challenges caused by this pandemic. COVID-19 has disturbed all essential activities especially education, business, healthcare, etc. People were forced to employ technology to carry out their day-to-day tasks like grocery shopping, education, business, healthcare etc. Various computing technologies such as Internet of Things (IoT), big data, Artificial Intelligence (AI) and Blockchain are being widely adopted to help track the outbreak of panademic, enforce restrictive measures, ensure availability of medical equipemnts, develop, and test vaccine. Blockchain is among these technologies that can be used as a potential problem solver to overcome numerous challenges. It has various key features, such as immutability, decentralization, and transparency, that can be utilized to benefit different sectors affected by the COVID-19 pandemic. This research aims to present COVID-19 applications that are based on blockchain technology. Further, we have illustrated the applicability blockchain technology in various fields like healthcare, education, government, finance, etc. We have also discussed a comparison of blockchain-based applications. Features and benefits of these applications are discussed along with the challenges associated with the adoption of blockchain-based COVID-19 applications. © 2022, Suranaree Journal of Science and Technology.
