Messaging Layer Security (MLS) is an IETF working group building a modern, efficient, secure group messaging protocol.
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
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 …
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.
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.
XMPP - The universal messaging standard
XMPP is the Extensible Messaging and Presence Protocol, a set of open technologies for instant messaging, presence, multi-party chat, voice and video calls, collaboration, lightweight middleware, content syndication, and generalized routing of XML data.

Explore the evolving Model Context Protocol (MCP), its security risks, and how to prepare for safe adoption as LLMs connect to external systems.
Element | Secure collaboration and messaging
Element is a Matrix-based end-to-end encrypted messenger and secure collaboration app. It’s decentralised for digital sovereign self-hosting, or through a hosting service such as Element Matrix Services. Element operates on the open Matrix network to provide interoperability and easy connections.
