Riemann Network (Riemann Network) is deeply involved in the field of big data. It is the underlying public chain that focuses on the research and development of artificial intelligence, distributed storage and VRF core technologies. It can realize data analysis, models, computing power, Storage and other multi-dimensional applications can be expanded, and then build a new generation of AI big data ecology of decentralized community autonomous data network. RAN is the fuel of the Riemannian network, applicable to a variety of application scenarios, and circulated in the Riemannian ecology.
