🇨🇭 How does a country turn open source technology into a national strategy?
At #MatrixConf2025, @maemst shared Switzerland’s journey towards recognising open source software as a key enabler of digital sovereignty.
@matrix is highlighted as a driving example — also used at the Swiss Institute of Public Sector Transformation — while projects like @zendis’s openDesk (including Element as the chat component) are being trialled in Switzerland’s public administration.
🇨🇭 How does a country turn open source into a national strategy?
At #MatrixConf2025, @maemst.bsky.social@bsky.brid.gy shared how Switzerland uses open source to enable digital sovereignty — EMOTA mandates gov software to be open source, while @matrix.org@bsky.brid.gy and projects like openDesk are being tested nationally.
How the new Swiss Open Source ...
🇩🇪 How do you build and roll out a messaging platform for an entire nation’s public administration?
At #MatrixConf2025, Kai A. Hiller from @bwi shared the evolution of BundesMessenger — Germany’s sovereign public sector messenger, built on the @matrix open standard, and based on Element.
It serves municipalities and federal agencies, offering a sovereign alternative to consumer messaging apps.

🇪🇺 At #MatrixConf2025, Alexander from @zendis shared how openDesk combines multiple open-source office tools to build a digitally sovereign collaboration tool for the public sector, using Element and the @matrix open standard as part of the suite.
openDesk powers a wide range of use cases - from the armed forces to public health and education - and is already being used in multiple countries.

🚀 From the legacy ESS Classic distribution to our new Helm-based ESS stack!
At #MatrixConf2025, Patrick Maier walked us through the evolution of Element Server Suite (ESS): our backend distribution for hosting and maintaining a Matrix-based system.
▶️ Explore Patrick’s talk in full; including how Synapse Pro unlocks massive efficiency gains and what’s next as we prepare migrations from ESS Classic to the new stack.

🇱🇺 At #MatrixConf2025, Patrick Weber shared how Luxembourg built LuxChat4Gov — a sovereign, secure and federated national messaging platform for the public sector.
🚀 Based on @matrix and using a fork of the Element app, it supports 11k+ public users; from ministers to firefighters and frontline staff!
▶️ Patrick’s talk revealed how a nation can move fast, adopt open standards and deliver trusted digital public infrastructure for everyone: https://youtu.be/xeRXFf4GDmw?si=JzxMKvx2Gx7G6VCF
🇩🇪 How do you consolidate government-to-citizen communications across Germany’s highly federalised public administration?
At #MatrixConf2025, Dominic Brown from @FITKOfoederal shared his work on building a federated, secure and user-friendly communications infrastructure for citizens and organisations.
@matrix is recommended as the default infrastructure, with pilot projects like NEO already testing Matrix-based messaging for administrative procedures.
Watch the talk: https://youtu.be/S4iQBWnuSRM?si=oMeZh-FEJTx1_sa9
🔐 From April 2026, only verified devices can send or receive end-to-end encrypted messages on Element.
This further ensures you can trust every message and stay protected from potential malicious activity, following the Matrix spec update announced at #MatrixConf2025.
Prepare by reading the actions required! https://element.io/blog/verifying-your-devices-is-becoming-mandatory-2/
With our talk “Eventually Consistent Access Control: Practical Insights on Matrix from Decentralized Systems Theory”, we were at the @matrix conference 2025 in Strasbourg: https://media.ccc.de/v/matrix-conf-2025-72768-eventually-consistent-access-control-practical-insights-on-matrix-from-decentralized-systems-theory [m]@🇫🇷🥳 The talk covers scientific foundations as well as 6 years of our own research on Matrix. #MatrixConf2025
Hier gibt's von der #matrixconf2025 einen Talk, der sich damit befasst wie man mit möglichst wenig Aufwand an einen eigenen Matrix-Messenger kommt - mit Codebeispielen anhand eines realen Beispiels.
At #MatrixConf2025, Mathieu Velten from @numerique_gouv shared the evolution of Tchap - the French public sector messaging tool based on @matrix
💡Tchap, a fork of Element, now has a server for each ministry and 375K active users as part of a large private federation. It is also part of La Suite, the collaboration platform integrating open source tools for public agents.
Tchap plans to adopt open federation to connect with external parties, such as local authorities.
🇩🇪 How do you onboard thousands of separate healthcare clinics and pharmacies to Gematik’s TI-Messenger?
At #MatrixConf2025, Patrick Maier shared how we're building large-scale, multi-tenancy hosting for TI-Messenger — gematik’s Matrix-based standard for secure healthcare communication.
This work ensures @matrix can support national-scale, sovereign healthcare communication — from millions of users to small practices — all in one federated, interoperable ecosystem.

@l3d maybe someone who visited #matrixconf2025 can point you in the right direction?
Just watched https://media.ccc.de/v/matrix-conf-2025-74565-commercialising-matrix
I liked:
• The mix of business and technology - we got both market-/business-model deep-dives and hands-on tech insights.
• The blend of feature showcase and SRE (site-reliability) insights.
If you’re working at the intersection of open source communication infrastructure, federation, sovereign software, or enterprise messaging - this is well worth your time.
thx @c3voc
Delighted to see Richard Speed from The Register writing up #MatrixConf2025 💚
💪 Europe’s enthusiasm for @matrix driven by digital sovereignty & geopolitics with strong adoption in France, Germany & Sweden
🇪🇺 EU Commission trial of Element
⚠️ The fragility of centralised systems
💰 The duality of governments embracing open source software, without thinking about funding upstream vendors
😮 Hypocrisy of governments adopting E2EE comms while supporting Chat Control
