GoKawiil's interpretation of the reporting above, not reported fact.
40C3 is Europe's largest non-commercial hacker gathering, run largely by volunteer labor and attended by tens of thousands who actively participate rather than just watch. The Call for Participation matters because it shapes the content and tone of a event that has long served as a proving ground for debates on digital rights, civil liberties and technology's role in society, especially as organizers frame this edition as a response to rising authoritarianism.
- 40C3 runs 27-30 December 2026 in the new, larger Hamburg Exhibition halls.
- Call for Participation is now open for talks, art, music, punk and entertainment content.
- This year's 'Model Citizens' theme frames the Congress as a counter-model to authoritarian trends in society.
