Matrix.org - Conference

Matrix Conf 2025 was a blast!

2025-10-30T12:00:00+00:00

The Matrix Conference 2025</a> is over, and it was a significant success for Matrix, its Foundation, and its ecosystem! If you couldn't make it to the Conference, here is what you missed and how you can catch up.

The first success was of course in attendance. With more than 250 attendees on-site and hundreds of attendees online, the Conference was attractive to many. This is particularly remarkable because the majority of our audience is in Germany, and this year's Conference was held in France. We want to thank our community for being so dedicated to Matrix and for following us here!

The Conference started by a Barcamp/Unconference: it's an informal workshop day where people join and share the topics they want to talk and hear about. In the evening we all gathered for a Welcome Party at bar Le Météor. Rocket.Chat and Element sponsored the evening, so attendees only had to come and grab food and drinks. We're grateful to both Rocket.Chat and Element for offering us this great night of socializing!

</figcaption> </figure>
The second and third days were the heart of the conference. The global show-up rate was high! Indeed, 96% of people who bought a ticket showed up. We asked people to optionally add their country of origin, and for those who replied 20 countries were represented. Matrix is already crossing seas and continents: the bulk of our audience came from Europe, but we also got representatives from Brazil, Canada, and Japan! We got 68 speakers, including 2 remote sessions and 1 hybrid session. We concluded the conference by a slower day of workshops on Saturday where people remained very engaged.
More than a day's worth of video was recorded by the excellent Audio/Video team. The Chaos Computer Club Video Operation Center</a> (VOC) indeed brought their audio and video equipment and expertise, and have set up a professional recording and streaming set up. They trained volunteers to use their equipment and home-developed software. Volunteers found it easy and great fun to operate the camera and audio/video mixers. We're grateful to VOC for their expertise, patience, enthusiasm, and calm all along the conference. They have been excellent people to work with.
Amazingly, talks were not only live-streamed, they were then available on our YouTube Channel</a> and on the Chaos Computer Club's own streaming platform</a> within minutes after the speaker stopped talking. Even more impressive? The VOC team members are volunteers.

We owe this conference to volunteers. More than 30 of them signed up to give their time and enthusiasm to the Conference. They took shifts to welcome people at the check-in booth, operated cameras, controlled the video mixers, helped during build-up and tear down, and generally happily asked for more things to do. We are sincerely grateful to everyone who showed up to lend a hand. It is heartwarming to be part of such an engaged community! If you want to join this welcoming community, drop us a line in the Events Working Group room</a>.

But all the goodwill in the world won't go anywhere without the finances to rent a venue, get catering, and cover the general expenses to organize a conference. We also owe this conference to the sponsors who showed up en masse to support the event! Our gratitude goes particularly to:

Our Anchor and Video sponsor Element</a>. You can find their Keynote, The Element Update: Shininess, Scalability and Sustainability on our YouTube channel</a>.</li>
Our Champion sponsors Rocket.Chat</a>, Automattic</a>, Connect2x</a>, Famedly</a></li>
Our Sustaining sponsors ERCOM</a>, Futurewei</a> and RISE</a></li> </ul>

If you missed the Conference, you will be able watch the videos on demand and find the talks slides on the Conference website</a> right after we finish adding the photos. In the meantime you can find them on our YouTube Channel</a> and on the Chaos Computer Club's streaming platform</a>.
If you wanted to get some Conference gear but couldn't get one of those fantastic Black & White T-shirts or hoodies, you have until Monday 3 November to order yours</a>.
Your next opportunity to catch up with us is at FOSDEM in Brussels, on January 31 and February 1, where we will be coordinating the Decentralized Communications Devroom. We also asked for a booth, but booth allocations haven't been announced yet. Heads-up that we will also organize a Fringe Event this year again, so make sure to be there a few days before FOSDEM!
You can follow what we're up to on our socials (Fediverse</a>, LinkedIn</a>, Bluesky</a>), you can follow our blog via RSS, or join our Matrix Space</a>.

Matrix for Public Sector: DINUM joins the Foundation as we launch a new forum!

2025-10-21T12:30:00+00:00

🔗</a>DINUM becoming the first government to join the Matrix.org Foundation</h2>
Today DINUM, the French Interministerial Digital Directorate, has officially announced that they were joining the Matrix.org Foundation</a> as a Silver member</a> and becomes the first government to join the Matrix.org Foundation!
This is particularly exciting news as it will hopefully set an example for other public sector organisations using Matrix to communicate, and there are many of them. 
In France, Matrix is the basis for Tchap</a>, the secure messaging system of choice for public officials. It was selected for its security, but also openness, transparency and sovereignty as it limits dependence on proprietary solutions from outside Europe.
With this support, DINUM is committed to:

participating in the governance of the protocol and enhancing its quality, in conjunction with other user states (Sweden, Luxembourg, the Netherlands, Germany...) and the open source business ecosystem;</li>
contributing to the development of the community versions of the various software components of the ecosystem, used by many public services;</li>
ensuring that its actions are part of a framework for sustainable investment in digital commons.</li> </ul>
DINUM has been an active contributor to projects of the Matrix ecosystem for a while, including by providing improvements to the implementation of Sliding Sync, which optimises performance and user experience; as well as the development of a community version of a border gateway, which enhances the security of the communications between distinct organisations.
Stéphanie Schaer, the Interministerial Director for Digital Affairs says: “With this partnership, we are choosing to make a long-term investment in a strategic digital commons for the benefit of the European ecosystem. Matrix is an essential building block for secure and sovereign communication services. This sponsorship reflects our conviction that the digital sovereignty of the State requires direct investment in the commons.”
🔗</a>Matrix for Public Sector</h2>
This announcement comes a few days after the second edition of The Matrix Conference</a>. The Conference was held in Strasbourg (France), gathering about 300 attendees, amongst which more than a dozen public sector organisations, brought together by their use of Matrix as a sovereign, secure and resilient communication protocol.
The Conference saw two full days of public sector track</a>, shedding light on the various exciting deployments of Matrix by these organisations. All the talks are already available for watching here</a>, and will be soon published on the website, but you can find a list of the public sector related ones at the bottom of this post.
We also took the opportunity of having many representatives of these public organisations present in person at the Conference to officially launch a Matrix for Public Sector forum. This is the very first group of its kind that the Foundation sets up and already many other industries are asking for something similar. The group will be proposed to the Governing Board for approval to potentially become an official Working Group</a>.
The goal of the Matrix for Public Sector forum is for the Foundation to bring together all public sector players who have already deployed Matrix or are looking to do so, and enable them to share knowledge, learnings and experiences, generally grow the usage of Matrix in the public sector, hopefully ultimately federating all these deployments into a proper Matrix network.

Launching the Matrix for Public Sector forum at the Matrix Conference 2025 </figcaption> </figure>
This seminal meeting gathered a dozen of organisations including representatives from France, the European Commission, Sweden, Germany, Luxembourg, the Netherlands, Belgium, the UK and Romania. The discussion focused on the type of knowledge and learning could be shared as well as how to structure the group.
All this activity, concretising years of growth of Matrix in the public sector is a huge step forward for the ecosystem, and we are very much looking forward to enabling this group of users to grow. It is also great to start implementing new ways for the Foundation to support the ecosystem and we can’t wait to replicate it with other industries!
And again: Welcome DINUM!

Announcing the Matrix Conference 2025

2025-05-23T08:00:00+00:00

The Matrix.org Foundation is happy to announce that the Matrix Conference 2025</a> will be held at Kaleidoscoop</a> in Strasbourg, France, from October 15 to 18!
Last year the Conference was completely sold out, with more than 200 decision makers, experts and enthusiasts joining us for this very first edition! The rooms were so full, and we had such a long waiting list that we've decided to extend our capacity this year to 300 attendees, with flexibility for more.
We would like to thank our Anchor Sponsor Element</a> for their dedication to the Matrix ecosystem and to the success of the Conference! Thank you, Element, for enabling us to make the Conference happen!
</a> </div> 
Last year we also received many good proposals that we couldn't fit into our schedule. This year we're adding an extra conference day so we don't miss out on great talks!


Wednesday 15 October will be a BarCamp: an informal workshop-like day where attendees can join, pitch a topic they want to discuss, and vote for topics they have an interest in.</li>
Thursday 16 to Saturday 18 October will be the three core conference days, with several tracks on topics ranging from Matrix in the Public Sector, Matrix for Sovereignty, Matrix Internals, Governance, and more.</li> </ul> 🔗</a>Call for Proposals</h2>
Our Call for Proposals</a> is open until June 8, 23:59 CEST. We're looking forward to reading what our community has been working on! We are open to all speakers but would like to particularly encourage people from groups underrepresented in tech to apply.
🔗</a>Get Eyes on Your Products</h2>
The Matrix Conference is a joyful event where enthusiasm flows between tech people who build the products and decision makers who enable them to do so by purchasing their products and services.
Don't miss out on this opportunity to get the right eyes on your product! With booths, sponsored tracks, logos on our streams and recordings and much more, this is your chance to advertise your products and services to the right audience.
