Earlier quoted context omitted.
The OP does not take issue with the algorithm part, but the claim of decentralization. I'm currently running my own instance of an ActivityPub server (GoToSocial), just for me, and it works like a charm. I would not know how to do the same with BlueSky, and I have tried to understand how.
If you’re trying to self host your account, you follow https://atproto.com/guides/self-hosting If you’re trying to build an application, you follow https://atproto.com/guides/applications If you’re looking to run the bluesky application, you need to run the codebases in https://github.com/bluesky-social .
Will my self-hosted account be able to talk directly to other self-hosted BlueSky accounts?
