HNB (Happy Nice Brand) is a high-speed cross-chain asset circulation underlying public chain built with multi-chain consensus, multi-chain parallelism, multi-source mixed consensus mechanism and cross-chain atomic operating system. HNB is a decentralized, fair, transparent and distributed game ecological platform based on blockchain technology architecture. With a decentralized structure, it directly organically links the components of the entire game ecological chain, realizing the direct connection of individual values, non-destructive circulation and safe storage. By eliminating monopolists and intermediate links, HNB game development directly serves players and is responsible to players; players decide the success or failure of game products through democratic voting, and jointly create the future of the game industry; The chain will record and explain, the chain will not die, the game and its assets will always exist; game development, operation and other work will no longer be provided by centralized manufacturers, but will be transformed into a "core team + volunteers" similar to an open source community organizational form. The interests and item information of users in HNB games will not disappear due to the failure of development. The blockchain data will last forever to protect the interests of users and players.
