The total amount of FP (Flow Pay) issued is 1 billion pieces. Users can get rewards by contributing value and purchasing computing power. The rewarded FP is used in all interfaces of the city agreement. FP pays the underlying application of the public chain, and the design of payment super nodes on the basis of FP solves the shortcomings of traditional payment (centralized management). The settlement of the traffic generated by all entities enters the entire computing power pool, and then feeds back to users of computing power of all nodes, which creates a self-ecological mechanical watch function, which is an ecosystem that operates on the kinetic energy of traffic and self-circulates. Coupled with multi-scenario modular payment and AI payment supervision, it brings a new "payment is mining" business model to the entire third-party payment market.
