盲盒遊戲開發（功能）丨盲盒遊戲系統開發（規則及詳細）丨盲盒遊戲原始碼部署

　　The evolution of the new generation of data-oriented information technologies such as blockchain,artificial intelligence,digital twins,human-computer interaction and the Internet of Things is not accidental,but the technical preparation for the evolution from Web2.0 to Web3.0.Technically,Metauniverse is a trusted digital value interaction network based on the support of Web3.0 technology system and operation mechanism,and is a new Web3.0 digital ecosystem with blockchain as its core.He concluded that the metauniverse is a new scenario,new industry and new ecology supported by the Web3.0 technology system with blockchain as the core,which will generate a large number of innovative business models and form a new paradigm of digital space in the digital environment

　　區塊鏈是Web3.0和元宇宙實現的技術基礎之一，當前的網際網路只能實現資訊的傳遞，尚不能實現價值的流轉，而Web3.0能真正實現“價值的連線”。這種價值的流轉也成為元宇宙實現的基礎。
