  The utilisation of blockchain has moved beyond digital currency to other
fields such as health, the Internet of Things, and education. In this paper, we
present a systematic mapping study to collect and analyse relevant research on
blockchain technology related to the higher education field. The paper
concentrates on two main themes. First, it examines state of the art in
blockchain-based applications that have been developed for educational
purposes. Second, it summarises the challenges and research gaps that need to
be addressed in future studies.
