This paper investigates the application of blockchain technology in the tourism industry, reviews its evolution and develops a future research agenda. A semi-systematic literature review was conducted of 98 publications from 2017 to the first quarter of 2023, indexed in the Web of Science database. This is followed by an in-depth analysis of the most recent papers (2022 to March 2023). The research focuses on the improvement of processes, their interaction with other technologies and adaptation to the environment. However, the studies show the need for further study on social and legal aspects. In addition, blockchain technology could be an enabling tool in the face of new sustainability paradigms or crisis environments. Finally, considering new lines of research, five dimensions were identified (social, organisational, technological, sustainable and economic) as well as the need to develop a regulatory framework and interaction with other technologies.
