"Understanding #Bluesky’s architecture clarifies how this happened. Built on the #ATproto Protocol developed since 2019, the system uses #PDS nodes (Personal Data Servers), Relays (servers that gather and distribute data), and AppViews (which render the user interface).
Critically, while anyone can run their own PDS for greater control, doing so requires technical effort and resources. As a result, the vast majority access Bluesky through the official app."
