In a wireless data network, Radio Access Networks (RANs) exchange user data between User Equipment (UEs) and core networks. The core networks exchange user data between the RANs and external data networks. The core networks transfer core information to distributed ledgers that characterizes the user data exchanges. The distributed ledgers add core data that characterizes core information state changes and store the core information. A data analytics engine filters the core data to detect core information states. The data analytics engine transfers core analytic data associated with the core information states.
