Rendez-vous routing
Also covering Hidden destinations, Blinded paths, and Route blinding
Rendez-vous routing, hidden destinations, and blinded paths are names for techniques that allow an LN node to send a payment to an unannounced node without learning where that node is in the network topology or what channels it shares with other nodes.
