Methods, systems, and apparatus are described providing networking engines. Specifically, a method for implementing software containers implementing network engines that may be configured to act in a zero-knowledge environment is described. All information pertaining to the network engine associated with a user that is stored in the container is solely that of a user unless explicitly shared by the user. The containers may be configured to participate in a publish-and-subscribe network in order to share information. In addition, the containers may be provisioned with controls so that global operators may comply with local privacy rules.
