A conceptual model of ATProto and ActivityPub
If you were to design an open social networking protocol, what would that look like? Which metaphors and comparisons would you use to get a general idea of how the network functions? And what would you answer if people ask if your network is decentralised and federated?

Bluesky released early documentation for the "AT Protocol" (atproto) a few weeks ago, and I've been noodling around with it. Technically, it strikes an appealing balance between rigid cryptographically signed content-addressable storage on the one hand, and familiar web-friendly schemas and integrations on the other. But at an ecosystem level, there are already a bunch of existing open social media projects. Does atproto bring anything interesting to the table? How might it fit in compared to other similar protocols?
What is atproto?
What is atproto? atproto is two things: A protocol for creating open social networks An open social network atproto, the open social network Today the atproto network has 36+ million users and powers Bluesky and a handful of other apps. Almost all atproto data is public. Content like posts, likes, follows, and photos/videos are publicly accessible to any network participant in a permissionless way. As an example of how open the network is, here’s how easy it is to stream all public data on the network using a public atproto Relay like bsky.network:

Decentralisation and blogging on atproto - Connected Places
The space for blogging and long-form writing on atproto is rapidly developing, and it gives some interesting insight in what decentralisation on atproto looks like
Many people are talking about decentralized social media protocols like #ActivityPub and #ATProto and all the amazing things one can do with them. But do you actually know how they work? We thought we'd do something about this. Come to #FediForum next week if you are curious and like to find […]
