+  - **Vidiverse:** same as Fediverse, but federating videos specifically.
   - **Instance:** a server which runs PeerTube in the fediverse.
   - **Origin instance:** the instance on which the video was uploaded and which
     is seeding (through the WebSeed protocol) the video.
+  - **Cache instance:** an instance that decided to make available a WebSeed
+    of its own for a video originating from another instance. It sends a `ptCache`
+    activity to notify the origin instance, which will then update its list of
+    WebSeeds for the video.
   - **Following:** the action of a PeerTube instance which will follow another
     instance (subscribe to its videos).
