Why a New Protocol? The History and Future of AT Protocol - AT Protocol
Bluesky CTO Paul Frazee and Head of Protocol Daniel Holmgren join for a wide-ranging conversation about what atproto is, why it exists, how it got built, and where it's going next. From a Twitter consultancy to an IETF working group, this is where to get started.

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?
Introducing ATProto Science - Cosmik Labs
Announcing atproto.science! #ATproto has huge potential for supporting new ways of doing research, so we started @atproto.science to help bring together researchers, build community, and explore what's possible when science meets cutting-edge open social network protocols! 🧪 >
Very cool project connecting atproto with the Underlay knowledge graph protocol "[The Underlay] is an archive. [atproto] is a wire. Together they give a collection both permanence and real-time distribution." And check out these neat #ATScience examples too! underlay.org/blog/2026-04-28-atproto-integ…

I love that the design of atproto was in part inspired by big social Kafka and ScyllaDB server backends and @martin.kleppmann.com's Designing Data-Intensive Applications and the community immediately used it to implement thousands of apps with no backend lol
