Up until now, every user on the network used a Bluesky PDS (Personal Data Server) to host their data. We’ve already federated our own data hosting on the backend, both to help operationally scale our service, and to prove out the technical underpinnings of an openly federated network. But today we’re opening up federation for anyone else to begin connecting with the network.

The PDS, in many ways, fulfills a simple role: it hosts your account and gives you the ability to log in, it holds the signing keys for your data, and it keeps your data online and highly available. Unlike a Mastodon instance, it does not need to function as a full-fledged social media service. We wanted to make atproto data hosting—like web hosting—into a fairly simple commoditized service. The PDS’s role has been limited in scope to achieve this goal. By limiting the scope, the role of a PDS in maintaining an open and fluid data network has become all the more powerful.

We’ve packaged the PDS into a friendly distribution with an installer script that handles much of the complexity of setting up a PDS. After you set up your PDS and join the PDS Admins Discord to submit a request for your PDS to be added to the network, your PDS’s data will get routed to other services in the network (like feed generators and the Bluesky Appview) through our Relay, the firehose provider. Check out our Federation Overview for more information on how data flows through the atproto network.

    This all implies Bluesky can be considered a massive tech corp (which it honestly isn’t even with investors, definitely not compared to Meta, or even Mozilla at this point), and can even be monetised.

    In the event that they do attempt that, users can move to a different PDS and not lose any of their data - that’s how AT was built. While on AP, it’s dependent on if the software powering the account supports migration, and even then I’ve not seen an implementation that carries over all of the user’s data (Mastodon only does followers/following, Lemmy has no migration whatsoever). That’s not to say it’s impossible, but I’ve not seen it happen.
