with the application of blockchain technology and metaverse scenarios, digital collections have become a hot spot and outlet for investment, and transaction disputes related to digital collections have also followed. Digital collections and virtual digital currencies represented by Bitcoin are all generated based on blockchain technology, which are unique, tamper-proof and non-replicable. Virtual digital currency transactions are prohibited by Chinese law, but there are no clear laws and regulations on the issuance and trading of digital collections. Many issues, such as how to determine the legal attributes of digital collections and whether their transactions are legal, not only affect the fairness and justice of individual cases, but also have an important impact on the development of industry innovation and new quality productivity.
