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.

Authenticated Transfer: Architecture Overview
Authenticated Transfer (AT) is a collection of protocol components that together provide a generic framework for interoperable social web applications, using global aggregations of interlinked, self-certifying data records. This informational document provides an overview of the entire system, as implemented in late 2025. Some of those components may be in scope as work for the IETF, while other components may not. Many components are general-purpose and may find use outside of the context of AT. The intent of this document is to provide context for how all the components can fit together for certain use cases.

#protocolsforpublishers #atproto #mcp #webapplets | Chad Kohalyk
Web publishing is facing its next challenge: a new iteration of centralizing platforms. BUT there is also a new wave of open protocols and standards that can help us gain our independence. Next month in NYC we are gathering a group of frontier technologists and popular web publishers to discuss how we can sail into this next platform shift as captains. #ProtocolsForPublishers Learn more and sign up here: https://pfp.unternet.co We will be hosting talks on #atproto #mcp #webapplets and web payments, and give publishers the opportunity to interact directly with developers working on these frontier technologies. Thank you to Unternet, Graze Social, Free our Feeds, and betaworks for their support.

AT Protocol
The AT Protocol is a protocol and set of open standards for decentralized publishing and distribution of self-authenticating data within the social web. It serves as the technical foundation of the Bluesky social network, originally developed as a reference implementation for the protocol, as well as an ecosystem of interoperable social applications and services collectively referred to as the ATmosphere.
Integrating Germ with AT Protocol — Germ Network
End-to-end encrypted Germ DM is now a Bluesky messenger. In this technical post, we introduce the architecture of Germ’s integration with AT Protocol. From the beginning, Germ has been building for an interoperable E2EE ecosystem, and this extends to our integration with AT Protocol. We’ll define th
