A process generates a certificate of authenticity for a virtual item. Further, the process sends, with the processor, the certificate of authenticity to a decentralized network of computing devices such that two or more of the computing devices store the certificate of authenticity. The two or more of the computing devices receive, from a user device that provides a virtual reality experience in which a virtual item is purchased, a request for authentication of the certificate of authenticity. In addition, the two or more computing devices authenticate the certificate of authenticity based on one or more consistency criteria for the certificate of authenticity being met by the two or more computing devices.
