⟠ ETHBrno×3

17-19 October 2025* @ Brno, Czech Republic

A three-day in-person hackathon for builders and privacy advocates collaborating on sovereign tools aligned with ⟠ Ethereum's original principles of decentralization and freedom.

*The date may still change. Final date will be available with the opening of registrations for participants during April 2025.

The Hackathon

Uniting 150 hackers in a sponsor-free environment. Instead of corporate-directed prizes, we will offer general awards based solely on innovation and alignment with sovereignty principles.

Our intention is to create a comfortable, family-like hacking experience with a fully equipped venue, provided meals, and guidance from veteran mentors — where every participant shapes the event's character while enjoying the freedom to create what truly matters.
