An implementation of Messaging Layer Security (RFC 9420)
What is Messaging Layer Security (MLS)?
Messaging Layer Security (MLS) is an IETF working group building a modern, efficient, secure group messaging protocol.
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 …
Making MLS more decentralized
It’s no secret that we at Phoenix R&D are big fans of the Messaging Layer Security (MLS) protocol, having helped it to come into existence. It’s a versatile group key agreement and messaging protocol that’s used to power both asynchronous and real-time applications. MLS is relatively
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.
ATSMS — end-to-end encrypted group messaging
Encrypted group messaging on AT Protocol identities, with no server ordering anything.
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

Permissioned Data Diary 2: Buckets - Daniel's Leaflets
The second in a series of posts building up a solution to permissioned data on atproto. We introduce buckets: a new protocol primitive for creating a shared social context.
