Datenspuren is an annual, three-day event organized by the Chaos Computer Club Dresden (C3D2), focusing on technology and society. This year, it will take place at the Zentralwerk in Dresden under the motto Under Construction.

Not only are the bridges in our galaxies, on our railway lines, and on our roads, but more and more bridges in society are also threatening to collapse. Fueled by the unreflective use of technology and engineering, societies are becoming divided and threaten to become alienated.
Therefore, under this year's motto, we invite you to join us in developing ideas and discussing how we can stabilize the bridges in society and build new ones.

Be brave and submit your ideas!

The Datenspuren live, like many other Chaos events, from your content. We are therefore looking forward to lectures or workshops from individuals and groups, related to:

Surveillance, data protection, open data
Decentralized and critical infrastructures
Sustainability, circular economy
Justice, breaking down barriers
Education for young hackers - soldering and programming

Your talk or workshop

Talks take 30–45 minutes on the stage and are, if you want, recorded and streamed.
Workshops take place in a separate room and are not recorded. Duration here is, as wanted, between 1 and 3 hours
All other formats are also welcome. Just ask!

How can I submit proposals?

Self-organized Sessions

Our courtyard offers plenty of space for spontaneously organized meetings and contributions during the Datenspuren 2025. Feel free to approach us about this at the event, and we will try to support you in the best possible way.

Call for Artists

We believe that art and technology are not opposites, but complement each other to create something special.
Therefore, we are looking for art installations, music, and other creative ideas to transform and shape the Zentralwerk during the Datenspuren into a colorful, futuristic utopia.

Possible submissions could include:

Music – anything from bands to intimate chamber performances,
Art installations ranging from light to sculptures,
Paintings, photos, and other pieces that can be displayed.

Your art could:

Take place on one of our various stages, in one of our rooms, or in the outdoor area.
Exhibitions can be set up across large parts of the venue by arrangement.
We are particularly excited about interactive art that invites participation.

Feel free to reach out to us, and we’ll help you bring your idea to life.

You can enter proposals until 2025-08-15 23:59 (Europe/Berlin), 2 months, 3 weeks from now.
