–The purpose of this study is to empirically evaluate the potential of the blockchain technology intourism. The blockchain technology (BCT) holds potential to contribute significantly to tourism policy andpractice. Academic interest in the BCT is rapidly growing with studies looking at the opportunities andchallenges of its application. The shortcoming of research on the BCT in tourism has however been in itsconceptual nature. The lack of empirical investigations hinders an understanding of how the BCT can bemore broadly adopted in tourism, especially from the viewpoint of minimizing its risks. Design/methodology/approach –The initial screening of the opportunities, challenges and risks is undertaken via a systematic literature review. The Delphi study is subsequently applied to empirically confirm what opportunities, challenges and risks can be attributed to the BCT use in tourism. Twelve industry and academic experts have contributed to the Delphi study. Findings –The risks identified have been categorized as societal, technical, financial and legal. Propositions have been made on how these risks can, at least partially, be overcome. Originality/value –To the best of the authors ‘knowledge, it is the first known attempt to study the B CTfrom the perspective of academic and industry experts. This research is also one of the first to evaluate the risks of the BCT use in tourism. Most risks are identified as not critical and can be addressed as the BC T develop
