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 June 2025.
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.
Join the hackathon (registration will open during June 2025)
The main venue will be Impact Hub Brno, a fully equipped co-working space located few minutes walk from the city centre and main train station, available to hackers 24/7 throughout the event.
We are looking for partners interested in the sovereign future of Ethereum. Please contact us and help us make this hackathon happen!
ETHBrno×3 is organized by the local Czech non-profit community Gwei.cz with the great support of the Web3Privacy Now collective.
