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

[mcc@mastodon.social]

@ellyxir I honestly don't think their architecture is very good

[jdp23@neuromatch.social]

@mcc mmmmkay it looks like Rudy is now in the process of "standing up an app.bsky.* API server" (aka appview) which "Is different from our community.blacksky.* API which is going on hold". So, my best guess is that his answer to you reflected the architecture (where the ommunity.blacksky,* API server is conceptually part of blacksky,.community) rather than the currently-available public implementation at the time.

(And no idea whether he's standing up an early implementation of their Rust appview or doing the off-the-shelf Bluesky appview or something else.)

@jdp23 What's interesting to me here is, the bluesky line is "ha ha it's super good everyone is angry at us because it accelerates federation", but you're making it sound like Rudy is having to upend his software engineering schedule to do stuff he otherwise wouldn't have had to do at all early, because of this incident forcing him to protect his users

@eniko @mcc if you're on your own PDS, you at least don't lose all your existing posts if bsky decides to permaban you. (If you're on one of their mushroom PDSes, they'll nuke all your content along with a permaban.)

[anna@hexile.witches.live]

@adrienne @eniko @mcc one thing i was never clear on, if you have your own pds and get permad, can you migrate and get around the perma, or is it some kind of cryptographic seed/hash of your pds data that's perma'd so you're fucked?

@mcc @jdp23 here guys this might help clarify why Rudy has to rearrange his epics in jira:

moderation can only be additive until/unless you pony up the CSAM/hashmatch API key money plus roll and run yr own mod sys at scale. thats the real Achilles heel of composable moderation-- replacing the bottom layer is incredibly expensive

[jdp23@neuromatch.social]

@mcc yeah have a look at Rudy's thread there, he makes that very clear. And similarly Northsky is saying well, our original plan was do PDS as Phase 1, Relay as Phase 2, and AppView as Phase 3, but now we're acceslerating Relay and AppView up and treating it all as Phase 1. My take is that everybody always took the approach of treating Bluesky PBC as a potential adversary but didn't expect them to be this adversarialy this quickly.

(If this is all an N-dimensional chess play to blow up the company to speed up the decentralization ... well as shitposting goes, that's pretty darned epic. But it's probably just horrbile comms accelerating and magnifying the tensions that were always inherent. Time will tell I guess.)

@by_caballero it's true that's a huge hole in the composable moderation model (and Rudy and others had been looking at it even before this -- https://discourse.atprotocol.community/t/how-should-we-fairly-split-the-costs-of-commons-moderation-across-producer-and-consumer-apps/122 is interesting thinking from the Eurosky perspective although doesn't yet point to any conclusions). But for this particular case they just need an appeal method for community members that allows themm to override the Bluesky mod service's app-level takedowns in their own AppView. On the deeper issue though I feel pretty vindicated because I've always said that composable moderation is interesting and valuable in some important use cases but doesn't actually solve the moderation scalability issue.

@anna @adrienne @eniko @mcc all the records in your PDS contain references to your identity (DID document), it's theoretically possible to modify the data to change that but requires rewriting your entire PDS for that account, so not particularly practical.

It's the DID that is moderated against in the higher layers, not your handle.

So it doesn't matter if you're @fred.example or @jason.example, if the DID used for one becomes the DID used for another handle.

It's kinda like how on ActivityPub, software has often encoded your username into the identifier for all your posts, meaning you can't change it without breaking everything.

(Though Mastodon is starting to fix this long-standing issue, there's fix only applies on new accounts, there's no protocol level way to fix it yet — it's kinda a weakness in JSON-LD)
