Follow up, 2025-12-27: Rudy here confirms the Blacksky appview is still being worked on (eg: blacksky uses bluesky's appview still)

The sticking point, as he describes it, is "backfill". This alludes to the issue that makes me compare ATProto to blockchain: to get the features users expect, every node on the network must mirror the network's entire history. This is impractical, which is why bluesky is as of this moment a federated network with effectively only one node.

Funding for Cash comes from CCI and the Cypherpunk Fellowship ($70K total). I am still working on the app-view. I hit storage limits on the previous server during backfill and needed to buy a $14K OVH Cloud instance.

:frogsiren: BLUESKY HAS OFFICIALLY NETSPLIT :frogsiren:

There has always been more than one Fediverse. Different instances make different moderation decisions so some instances can't see posts by some users.

There has only ever been one Bluesky because every ATProto frontend uses the same Appview.

It is January 2026 and that's no longer true; Blacksky's Appview is available for beta use and there is at least 1 user banned on Bluesky but not Blacksky. And vice versa.

Bluesky runs an appview. Blacksky runs an appview. A complete appview is a several terabytes sized database of the >18 billion follows, likes and posts of all bsky users, ever and forever. To run a different appview is to make a fork in bsky’s timeline. One has new posts from Łink. One doesn’t.
