I would like to give an update on "federation" on Bluesky.

@ikuturso @benroyce @txtechnician @mcc
How much has actually been invested in Bluesky? Public information (https://accessipos.com/bluesky-stock-ipo/) is three rounds, a seed round and an $8M in 2023 and $15M (Blockchain Capital) in 2024. In January 2025 a round lead by Bain Capital (https://www.businessinsider.com/x-competitor-bluesky-valuation-new-funding-round-2025-1) was reported setting valuation at $700M, but no further info if that round closed has been reported. Is the total to date $23M plus seed accurate? What happened with the big January Bain Capital round?

@ikuturso @benroyce @txtechnician @mcc
In general, their finances are very opaque. Some are saying that the $15M can last them for 2 years, but it is hard to understand how a 25 person silicon valley company with 100 contract moderators, and no revenue can be running at $625K per month. In any case, as mentioned above, either they have to start raising more money or they have some other undisclosed source of funding.

@aeva @cthos either you rely on bluesky to get the content (meaning you have to trust them to convey the content) or you prepare and mirror the content yourself. No real third option, fundamentally. If there were several blacksky-like towers then they could potentially pool resources, but no other actor has gotten as far as blacksky so there's no one to pool with.
This is just me thinking out loud without much direct knowledge, but isn't live Atmosphere content supposed to remain available on its home PDS indefinitely? So couldn't an AppView implement an LRU cache rather than a full mirror of all content? Or does this storage cost come from something else that can't be trivially re-fetched later?

Update: Rudy who operates blacksky.community responded to this thread on bluesky. Above I said I wasn't clear on how independent Blacksky was of the Bluesky infra. His answer is "completely". They run their own relay (which scrapes PDSes itself), the relay feeds into their own appview, the appview feeds into their own client. https://bsky.app/profile/rude1.blacksky.team/post/3lyv5rwpc722c
And since they bridge end-to-end, in my Hypothetical Example above, they *could* choose to make different moderation decisions from Bluesky PBC.
@mcc what about the PLC DID directory?
AFAIK:
1) ‘blacksky community’ doesn’t have control over ‘their accounts’ as long as they don’t run their own directory.
2) running an ‘independent directory’ means: no zerocost migration between networks and no coherent communication between networks without bridging elements.
I find it distressing that, as of now, most bsky documentation still omits the fact that the directory underpins *everything*.

@cypherhippie PLC is bullshit and honestly, I believe it is not possible to work around it. Or rather I have an entire design proposal for how to fix plc (replace it) and I know at least one other person with a design proposal for how to fix it (by replacing it), but I don't know how to solve the social part because the social part is "convince bluesky to give up power" and I can't think of a reason they'd do that.
-
And that's why I say, TLDR:
- I am legitimately excited about the work being done by Blacksky Algorithms! I am using their frontend and happy with it.
- Northsky is an interesting development to watch
- If you're on a Bluesky PDS, I recommend migrating off with one of these tools https://bsky.app/profile/did:plc:ii5jchdzlmcojjw4dqczcgkh/post/3lyt6t6qfa22u
- Everything Sucks. A LOT of things would have to change at a social level for *any* entity other than Bluesky to have power or independence in the ATP ecosystem. I still don't trust Bluesky.
@mcc I'd love to migrate but it's all and I mean ALL way over my head

@mcc Right now there are people hosted on Blacksky who cannot post because they are banned by Bluesky.
I've been asking Rudy about how independent Blacksky is from Bluesky but have not heard back yet.
From what someone said, it seems that Blacksky is using the Bluesky labeling system which performs moderation. Thus, to be banned on Bluesky means you are locked out on any instance that uses its labeling.

So. The thread above. An update.
We finally got a live test of the "Gertrude scenario", when a popular Blacksky user got permbanned by Bluesky. I, using my own PDS and blacksky's website, can't see him or his posts ( https://blacksky.community/profile/did:plc:2aebn3xk5t63net43eeepire/post/3m2iokicegs2b ). What gives?
A lot of people claim this is because Blacksky really is using Bluesky's appview, and gave me a way to verify this looking at headers. This seems to contradict Rudy's previous claims. I've asked Rudy for clarification: https://bsky.app/profile/did:plc:2aebn3xk5t63net43eeepire/post/3m2jve23cf22m

@mcc my understanding - and this may be completely useless, but I've read a bunch of threads by a bunch of people - is that (a) the Blacksky app view migration is still in process, and that (b) Bluesky is still working on migrating their moderation from the firehose (where it isn't supposed to be) to the app view (where it is supposed to be).
Either of these might cause a blocked user to fail to appear in the Blacksky front end.

@tess But
1. Even if Blacksky's appview is limited to the last seven days, or limited only to information Blacksky controls (eg the blacksky pds), I should still be able to see Link's posts, or Link's last seven days of posts. So it seems blacksky's appview isn't being used at all.
2. The test linked above, too, seems to imply I am using Bluesky's appview in all cases.

@mcc Is Blacksky operating its own relay? Is it possible to ban users at the relay level?

@mcc Link, the banned user in question, is accessible via the raw Bluesky network feed (the "fire hose"). But he cannot be viewed by any server that utilizes Bluesky labelers. Does your PDS?
It seems as though Blacksky does, which is why he can't be seen there. But he can still post. I'm in touch with him and he's posted to me, which you can see here in the fire hose: https://pdsls.dev/at://did:plc:63hvnyjvqi2nzzcsjgnry5we/app.bsky.feed.post

@mattsheffield The pds doesn't view posts. The appview views posts. You need like five separate components in order to look at a post on Bluesky and every single one of them introduces the potential for censorship. I can't read the site through pdsls that's bonkers

@mcc The layers are indeed censorship choke points.
What I'm saying is that in this case, it appears to be the labeler of Bluesky that's the issue. Any app view that uses it will suppress Link's parts, even if he's not banned locally.
The app view of Blacksky would hide him locally but he wouldn't be banned. This is why he can post but can't see his own posts. The Blacksky app view (the site) is independent except for the labeling.

@mcc that all scans, and, I hope it's just a miscommunication as to the current state of BlackSky.
If nothing else, this is the five-alarm fire that should expedite the switchover.

@tess I am inclined to give Rudy a lot of leeway because he is clearly moving very fast. I'd rather him engineer than answer my questions and I'd rather not interrupt him while he's engineering a thing I want to use.
But I just want to know what the software I'm using… like… is.

@mcc *sigh* i get it
I'm holding out for Northsky even though I fear it's going to be the typical flameout but the fact that BlackSky is offering PDSes to people outside the community is also super appealing.
Seeing how they handle this situation might be what puts me over the edge.
That said, I'm also not trying to build my own tools; just use a nice platform run by people I trust.

I feel like I'm having a lot of repetitive conversations. The thing you are claiming was my conclusion as of last night, but then I was shown an additional piece of evidence, which makes me conclude something different. This was documented in one of the threads I link above, but I link a lot of things above, so I assume you didn't see it. I can explain it, but it would make more sense to just wait for Rudy (who I've asked for an explanation) to explain.
