* [MD] Metadata-private messaging designs that can accommodate millions of users, are inflexible. They restrict users to a single online device that transmits data at regular short intervals and demand users to specify when their friends can send them messages. This creates high network and energy expenses for the clients, restricting users to communicate through a single powerful device, such as their desktop.
Groove is the first scalable metadata-private messaging system that gives users flexibility: It enables users to use multiple devices, send messages to friends at any time, and even when the friends are offline. Additionally, Groove conserves the user's device bandwidth and energy.
All this is possible by introducing protocols for oblivious delegation that allows users to have an untrusted service provider participate in the rigid messaging protocol on their behalf.
