There is no doubt that the future will excite and thrill everyone. With the continuous breakthroughs in the underlying technologies such as blockchain, VR/AR and network transmission, people are more convinced that the day will surely come. However, the decentralization of application, as the core requirement to ensure the eternal life, free creation and security of the metaverse, is still not fully implemented: nowadays blockchain can only support the decentralization of digital assets of DApps but can't support the large-scale and complex computing, so almost all applications such as logical computation, data storage and image rendering are centrally processed to control the distribution of the digital assets on the blockchain. In this way, the whole metaverse will be controlled by the minority, and all users will be the captive lambs in the virtual world. A real metaverse must achieve the full decentralization of large-scale applications. For this reason, we build the Ethanim.
