## User Layer

* **Device Integration:** Profiles sync locally.
* **Online Uplinks:** Internet-bridging nodes for scaling adoption.

### Online Uplinks

* Act as switchboards between offline and online worlds.
* Identify nearest regional nodes for message relaying.
* Ensure data validity & global availability.
