The primary features of a real metaverse are interoperability, openness, and sustainable community autonomy. Moreover, we hope the DeHorizon metaverse is the place each player can build their second life. This means DeHorizon metaverse should provide a premium user experience, design attractive GameFi gameplay, establish world-famous IP collaborations and much more. Having such ambitious goals means that DeHorizon metaverse is an enormous undertaking. Thus, we begin with DeHorizon metaverse 1.0. Several DeHorizon games are already under development and will pave the way for the first version of DeHorizon metaverse, a place where players can play for fun and to earn.
