Meanwhile, behind the spectacular growth of the metaverse market, there is a dark shadow of proof of ownership, the absence of an integrated platform for virtual reality and metaverse, and an unreasonable content revenue structure. In other words, when the value of goods traded in the market increases as the metaverse market grows, proof of ownership of the item is required. In addition, there is still a lack of a proper integrated platform that can bring together virtual reality users and metaverse contents. In addition to this, in addition to content sales, developers can make profits by utilizing the economic ecosystem configured in the metaverse, so attractive content must be abundantly supplied to the market.
