The Chaos Communication Congress is the Chaos Computer Club’s (CCC) annual symposium and hacker party. During four days between Christmas and New Year’s Eve, thousands of hackers, technology freaks, artists, and utopians get together in Hamburg to communicate, learn from each other, and party together.

This is the CfP for the first "community stage program" covering the tracks: Diversity & Inclusion, Hack, Make & Break, Privacy, Anonymity & Decentralisation, Open Source & Platform Decay (Enshittification), Sustainability and Entry-Level & Education.
