Tent is decentralized, not federated or centralized. Any Tent server can connect to any other Tent server. All features are available to any server as first-class citizens. Anyone can host their own Tent server. Tent servers can also be run as Tor hidden services to create a social darknet for at-risk organizers and activists. Anyone can write applications that connect to Tent in order to display or create user content.
Relationships are between users, independent of their service providers, so users take their data and relationships with them when they change Tent service providers. Every user decides which other users can follow them and what information will be shared with each of their followers.
