This document specifies how the Authenticated Transfer (AT) Protocol can leverage Media over QUIC Transport (MOQT) for efficient data synchronization across decentralized social networks. The AT Protocol's firehose event stream and repository synchronization mechanisms map naturally to MOQT's publish/subscribe model, enabling scalable relay infrastructure, priority-based delivery, and improved resilience for large-scale social data distribution. This specification addresses the challenges of the current WebSocket- based transport and demonstrates how MOQT's relay architecture, group-based caching, and multiplexed streams provide significant benefits for AT Protocol deployments at scale.
ATProto for distributed systems engineers - AT Protocol
AT Protocol is the tech developed at Bluesky for open social networking. In this article we're going to explore AT Proto from the perspective of distributed backend engineering.

Walkthrough of the various parts and concepts in Bluesky's AT Protocol (ATProto), the types of servers involved and how it all fits together
Introducing Tap: Repository Synchronization Made Simple | Bluesky
Just about every app built on AT needs data from a repository at some point. For many use cases – feed generators, labelers, bots – streaming live data through a Relay or Jetstream works well. But some applications need to go beyond what Jetstream was designed for, like tracking specific subsets of a repo, automatically backfilling a database when adding new repos to monitor, or even mirroring the entire Atmosphere.

AT Protocol
The AT Protocol is a protocol and open standard for distributed social networking services. It is under development by Bluesky Social PBC, a public benefit corporation originally created as an independent research group within Twitter, Inc. to investigate the possibility of decentralizing the service.

From ZK-first to AT Protocol — our path to DDS | Agora Citizen Network
We've been building Agora — a platform for public deliberation using Polis-style clustering — for a while now. Along the way, we've written about what we think about Nostr, AT Protocol, Polis, Community Notes, and protocol interoperability. Those posts are somewhat outdated now. This one describes w...
