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
Germ DM x ATProto is Now in Beta — Germ Network
Germ DM is now a Bluesky messenger. We’ve integrated AT Protocol into our iOS app, so E2EE DMs have come to the Atmosphere! Germ DM is the end-to-end encrypted messenger that lets you talk freely—without a your phone number. It’s powered by Messaging Layer Security (MLS) and now connects to your A

Germ Network
Share what you want to, when you need to, on Germ DM. The only messenger with multiple profiles, no phone numbers, and end-to-end encryption.

Autonomous Communicator (AC) Protocol — Germ Network
“Hi, I’m Mark, here’s how you can send a message to me.” Our Autonomous Communicator (AC) Protocol empowers people to autonomously define identities which they can exchange with others to form relationships for communicating over end-to-end encrypted (E2EE) messaging channels.

ATSMS — end-to-end encrypted group messaging
Encrypted group messaging on AT Protocol identities, with no server ordering anything.

Introducing the Model Context Protocol (MCP)An open standard we've been working on at Anthropic that solves a core challenge with LLM apps - connecting them to your data.No more building custom integrations for every data source. MCP provides one protocol to connect them all: pic.twitter.com/kYsivQyPDq— Alex Albert (@alexalbert__) November 25, 2024


Decentralized Pairwise MLS — Germ Network
Today, MLS is predominantly used in a centralized context, where a central entity hosts group state. Germ now leverages this powerful technology for decentralized 1:1 conversations, by letting users cooperatively advance group state.

OAuth for AT Protocol | Bluesky
We are very happy to release the initial specification of OAuth for AT Protocol! This is expected to be the primary authentication and authorization system between atproto client apps and PDS instances going forward, replacing the current flow using App Passwords and createSession over time.

Investigation into Message Layer Security (MLS)
This article investigates Message Layer Security (MLS), the IETF standard protocol (RFC 9420) for Signal-style end-to-end encryption. Through a practical analysis of OpenMLS (the Rust reference implementation) and a demonstration CLI chat application (mls-chat), the post reveals the substantial gap between protocol specification and production deployment. Introduction MLS (Message Layer …

ATOM: AT Protocol Over MoQ Transport
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.
