About the Association

MRMCD e.V. is a registered non-profit association that organises the annual Meta Rhein-Main Chaos Days – one of the longest-running chaos events in the German-speaking world.

Since 2004, hackers, netizens, privacy advocates, artists, and curious minds have gathered in Darmstadt to discuss, learn, and tinker around technology, society, security, and digital freedoms.

Each MRMCD revolves around a new motto. Alongside talks and workshops, the open, community-driven atmosphere is what makes the event special. The association is closely aligned with the Chaos Computer Club (CCC) and shares its principles: freedom of information, public access to computers and networks, and a responsible handling of data.
