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.
FOSDEM 2026 - Lighter, faster, simpler: An Element Web for the future
Element Web is the oldest and most widely deployed Matrix client, and could well be the most widely deployed decentralised comms client in active service, especially when considering its many forks (Tchap, openDesk Chat, BundesMessenger, SchildiChat, LuxChat, etc.)

why not matrix?
at this point it seems like most of the tech community is familiar with matrix, the "open network for decentralized communication". lots of projects and communities have migrated from a host of other platforms, including irc, discord and slack with the promise that their new spaces will be free forever. i first discovered matrix in 2021 and have dedicated a lot of time trying to understand exactly how it works, as well as trawling through github issues to try and understand whether we should consider matrix…
Room to grow: Building collaborative, open software
We examine one approach to collaborative, open software by building on Matrix, a secure, decentralised, real-time communication protocol with generic database capabilities hiding beneath its current focus on chat.

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
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.
