Trying to figure this out as in the recent threads a few people said that Bluesky was federated, but it didn’t seem to actually be the case.
https://bsky.social/about/blog/02-22-2024-open-social-web in February announced that Bluesky would allow federated servers
The Bluesky documentation on the topic isn’t very clear. They mention Bluesky.social a lot, as if it’s supposed to be the one central server other PDS need to federate with:
Bluesky runs many PDSs. Each PDS runs as a completely separate service in the network with its own identity. They federate with the rest of the network in the exact same manner that a non-Bluesky PDS would. These PDSs have hostnames such as morel.us-east.host.bsky.network.
However, the user-facing concept for Bluesky’s “PDS Service” is simply bsky.social. This is reflected in the provided subdomain that users on a Bluesky PDS have access to (i.e. their default handle suffix), as well as the hostname that they may provide at login in order to route their login request to the correct service. A user should not be expected to understand or remember the specific host that their account is on.
To enable this, we introduced a PDS Entryway service. This service is used to orchestrate account management across Bluesky PDSs and to provide an interface for interacting with bsky.social accounts.

Self-hosting a Bluesky PDS means running your own Personal Data Server that is capable of federating with the wider Bluesky social network.

The custom domain name is still something else, and does not seem to require a PDS: https://bsky.social/about/blog/4-28-2023-domain-handle-tutorial
So, to come back to the title question, do people know of an example of PDS that can be used to access Bluesky without being on the main server?
Long winded, nuanced answer, ready your eyeballs:
It’s a bit complicated, but since we’re on Fediverse and at least somewhat familiar with how things work here, I’ll try to explain with that comparison in mind.
On Fediverse, instances are in control of the user data directly. To “migrate” your account, you’d be switching instances and admins entirely.
BlueSky splits things up quite a bit more.
There, you can host your own “PDS” or Personal Data Server. That hosts your account and post info only.
Then, there’s the “AppView”. In comparison to Fediverse, these are like Lemmy, Mastodon, Mbin, etc. Right now, there’s VERY few Appviews to choose from.
Then, there’s the “relay”. Which to Fediverse, the only thing similar is also relays, but they work differently. On BlueSky, they relay every post and interactions of all the PDS data that connect to AppViews. I do not think there’s a choice on *what* is relayed, just a huge firehose. That being said, they’re not optional like Fediverse. To complete the network, relays are required on ATProto and apparently could be expensive to host, so right now, it appears the only relay is hosted by BlueSky the company. Which makes things slightly centralized.
Now, that we have those definitions out of the way, this is where things get a bit muddy and a bit of purposeful corporate created confusion for purpose of selfishness is quite apparent.
Right now, there’s very few AppViews. The ones I’m aware of are, BlueSky itself, Whitewind, and Frontpage.xyz.
The confusion happens because BlueSky, the company, doesn’t separate the fact that accounts hosted on self-hosted PDS, aren’t technically Bluesky accounts, they’re ATproto accounts. Everywhere you look to login, it says “login using your BlueSky account”. I can only assume they’re doing this on purpose so that anyone who tries to make an Appview, host a PDS, AND a relay, can’t have their own “identity” like different instances and platforms have here on Fedi.
That will confuse people and make them think *everything* is just hosted by BlueSky the company. However, as we’ve now established, there’s definitely a separation of “Bluesky” the company, “BlueSky” the AppView that you can login to using your “BlueSky” account, which doesnt technically have to be hosted by anything related to BlueSky.
I hope this all makes sense and you can tell that *technically* things are decentralized for the most part. It’s just that BlueSky is purposefully muddying their own definitions of things so that anyone that tries to build on ATproto, has a hard time making themselves known as *not* bluesky due to the way they conflate all these definitions.
Sorry for the huge post and hope it makes sense in some way.
Thanks for reading.😁👍
Thank you for the detailed explanation!
@Blaze no problem, friend.
I always worry if my long winded answers make sense to neurotypical people as I’m ADHD and slightly autistic.😅
So I hope it does make sense, at least even partially.
Overall, they’re mostly centralized because there’s *very* few relays and they’re required infrastructure, but decentralized in other ways, which may or may not matter in the bigger picture because of this previous information.
Your answer was concise and succinct, for such a complicated topic. Thank you!

Damn. This needs to be a blog article and saved somewhere! No need to apologize. You’ve done a great job explaining a very technical topic in a simple and relatable way.
@mark thank you for the compliment and assurance friend.
I am always self conscious about my long winded replies because sometimes even I wouldn’t wanna read a post that long.
Though, with topics like this that I’m very passionate about, I feel it’s very important to lay out all the information and knowledge I have so that others can make informed decisions themselves based on the most important details.
I discuss Fediverse and networks like it, literally constantly and there’s LOTS of nuances with these systems that need lots of explanations.

No need to be self-conscious - that’s a concise account of a complicated issue, which is going to go long. Long posts become an issue when they are rambling and unfocused.
So its activitypub, but worse because its designed from the ground up to be difficult to federate? Bro just use twitter at this point.
That’s a wild interpretation of what they said.
Dude described a branding problem, not a technical problem.
Man this is a Bruh moment comment from me, My bad guys
Bro just use twitter at this point.
That’s like choosing gangrene on your foot because you can’t decide which shoe to wear and tying the laces seems like a pain in the ass.

Or maybe they do it because it would be very confusing for 99% of users to read “sign in with your atproto account” when no one knows what that is. Its a good thing theyre keeping things simple for now instead of getting the mastodon “its too complicated” issue and having non tech users not use it.
Mastodon and the activitypub culture is very much either “its too complicated” or “how do you not understand its so simple maybe you’re just dumb and shouldnt be here” energy and its why 99% of topics here are just tech and politics. Almost no artists use it and the few that use it are on mastodon.art which defederates from so many instances.
Eu ainda não explorei a ferramenta. Entrei no Fediverse em vários lugares e estou meio perdido.
@Blaze AT (Bluesky’s protocol) is a little bit different then activity pub. There’s two types of servers, a PDS and a relay. A PDS is basically a git repository of all your posts/interactions, it’s super lightweight and doesn’t do anything but host them and provide it to any server that asks for it. The PDS basically does the profile hosting portion of a Mastodon server, and is very similar to a Nostr relay if you’re familiar with that.
A relay accesses data across a bunch of PDSs and provides it as one big network to the relay’s users. It’s basically the equivalent of the federated portion of what a Mastodon server does. It’s also doing what a Nostr client does (although Nostr does that on the user’s device) if you’re familiar with that.
Any relay can pull data from any PDS, so theoretically it’s very decentralized since anybody could host either a PDS and/or Relay. Bluesky was opened up very recently though, so there’s not many non-Bluesky-hosted PDSs on the network yet and most are small and experimental. There’s also no relays other than Bluesky that I’m aware of, although it’s only been open for ~6 months so I expect that’d change soon.
I think they do but they use AT protocol (theirs) instead of ActivityPub so that’s why you don’t see them in mastodon and they don’t have many servers in federation
Indeed, but I’m a bit surprised there isn’t any list of alternatives servers.
I would have to look more into the protocol specification, but it seems like this isn’t really federation, alternative servers are still relying on the central server, and that’s why nobody bothers with setting one up
Why would someone host a server and pay for it out of their own pocket, when the protocol just turns in to an invisible piece of infrastructure that people don’t even know exists?
AP instances allow for communities and identity to build around them, so there is a non monetary incentive to running them, but what’s the incentive to run an equivalent on bluesky and make it public?
That sounds like a really dumb design idea. Why make a federating protocol if you still rely on the server? I don’t even get why they did it at all then.
That’s indeed very interesting and peculiar.
They could pretend to be federated while they’re not.
Might show them in a more positive light to the general public
So, from up close it seems like people can have their own servers (i checked wurzelmann.at which is currently on the frontpage) but they do not seem to have their own frontend.
This indeed makes it so that for people to actually SEE your content you must federate with one entity and are controlled by them.
Imo this is very bad because it takes the freedom out of federation. Yes, you dont need to login to an app but if they ban you or defederate or delete your post, nobody will see it, right?
Please someone who has tried and gets the technical details shed light on this.

@Blaze $150-$300 per month is what a relay costs for the entire 10M account network. That is extremely efficient.
It’s also not necessary. Smoke Signal the events on ATProtoo connects to user PDS directly.
So what would happen if a billionaire buys out Bluesky and starts spreading right wing propaganda all over it?
Completely hypothetical scenario
Same thing if some Billionaire purchased Mastodon.social & Mastodon.online. You’d have most of the fedi under their control
But then people would still be able to easily instance switch. That’s not something that is possible for Twitter
But you weren’t discussing Twitter you were discussing Bluesky. They built it with decentralised identities so that users owned their identities and can move about freely. You saying people could “easily” move to another instance isn’t reality. People already find the Fediverse too difficult, as you and I discussed under a different thread people actually care about their data which also includes their posting history. Humans by nature do not like change. People complain about Mastodon.social being too big to block. So, if people that want to block mastodon.social due to what they believe is poor content moderation but feel they can’t because of its size how likely that people would find it “easy” to move to another instance ?
Indeed, I hadn’t looked at the full context as it’s a month old thread.

Could you provide an example of a relay that is not managed by Bluesky?

If we already discussed this, then is it worth it to go over this again?
