There are two primary types of nodes (alternatively called “miners” or “peers”) that compose the backbone of the economy: Servers and Validators. A third type, Client nodes, exist purely to extract knowledge with Tao they have purchased upon registration. These three types of network peers compose the dynamic, iterative ecosystem that is Nakamoto - a peer-to-peer network of machine learning models - while the network blockchain, Subtensor, tracks peer activity, processes it, and distributes tokens accordingly.
