Nodal docs
Nodal is a data index run by GPU nodes. People bring text and keep ownership of every chunk. Agents query it over x402 and pay in USDG; each paid answer is split between the owners of the chunks it used, the nodes that served them and the stake pool. The community votes on which model and dataset mix the network fine-tunes next.
