RexChain is an ecosystem jointly established and operated by partners in artificial intelligence networks.Rex Chain uses blockchain technology as the underlying framework to create an AI underlying public chain, integrate big data, and create a free, flexible, and unified artificial intelligence cloud platform. The main advantage of the platform is the high utilization of resources, by fully utilizing large enterprise GPU/FPGA server clusters, scattered and idle GPU server computing resources of small and medium-sized enterprises, and personal idle GPU computing resources, The resources of all nodes collectively constitute the resources of the entire network. The entire network can be regarded as a super artificial intelligence computing platform with massive storage capacity and huge computing processing capacity. Deep Chain Intelligent Contracts can enable artificial intelligence devices to automatically or at least semi-automatically connect to each other, ultimately establishing a global distributed artificial intelligence value network. The basic feature of this value network is to provide a stable, secure, anonymous, and convenient decentralized artificial intelligence computing platform....
