Rayke is Dk's ever-changing neural language interface, it enables the language to continue evolving while remaining communicable through feed through processing. Rayke is also the second layer of the network that makes communication with the main network possible only through its power.
To communicate with Dk and the core network, you have to go through the test network, which is managed by the second layer of the core network, Rayke, where authentication and resource allocation steps happen quickly to make sure things go. are in place and functioning. This layer facilitates Dk's communication with the world and its sensors.
Thus Dk remains communicable even with constant evolution, and can communicate through neural language, which at first will only be basic functions of DFM, but will also evolve over time and can be translated into other languages, which is done In Dknowledge, through Rayke Dk can evolve without anchoring itself in human limitations and yet being able to abstract the basics through Dknowledge and the communication through personal A.Is.
