@douwe@waag.social Christine Lemmer-Webber did a great analysis a while ago:

How decentralized is Bluesky really? -- Dustycloud Brainstorms

(dustycloud.org)

It's a great place to start.

@douwe This article by @danabra.mov is pretty helpful: https://overreacted.io/open-social/

@evan that is indeed a while ago. As far as I understood ATproto has made significant improvements for federation since...

[evan@activitypub.space]

@douwe@waag.social The protocol itself hasn't changed radically in the last 18 months. If you want to understand ActivityPub and ATProto's similarities and differences, you can't find a better analysis than Christine's. She is one of my co-authors on ActivityPub, and she really dug deep into both protocols.

@douwe heya!

Here are some #atproto resources both architecture & conceptual https://semble.so/profile/bmann.ca/collections/3m5u77miiyf2h

My own Beyond Microblogging talk is a bit dated but will give you examples and a crash course https://bmannconsulting.com/notes/beyond-microblogging-atproto/

@douwe core concept: accounts are hosted separately from apps, so one account logs you in everywhere.

All data is stored in your account, and different apps can re-use types of data (called Lexicons).

Here’s a second view of the bookmarks I linked above, in a different app https://margin.at/bmann.ca/collection/3m5u77miiyf2h

Apps can be quite simple, because functions are spread across different parts of the architecture.

Feel free to ask more! My atproto account is bridged here @bmann.ca
