Nowadays, breakthrough technologies, such as virtual reality (VR), augmented reality (AR), and Blockchain, have definitively attracted the attention of a huge number of investors worldwide. Although, at first glance, Blockchain (traditionally used for financial services) seems to have little to none to share with VR and AR (originally adopted for entertainment), in the last few years several use cases started to appear showing effective ways to integrate these technologies. In this article, an overview of opportunities investigated by current solutions combining VR, AR, and Blockchain will be discussed, showing how they allowed both companies and academic researchers cope with issues affecting traditional services and products in a rather heterogenous set of application domains. Opportunities that could foster the convergence of these technologies and boost them further are also discussed.
