@ ETHBrno² - Privacy & Security
Register here 👉
Becoming an active participant is the only way you can get a ticket and secure your participation in ETHBrno². We're expecting a few hundred hackers (or volunteers, speakers, mentors, judges) and we won't be selling any tickets.
You don't have to be a smart-contract developer or programmer to participate in our hackathon - you can be also a copywriter, economist, graphic designer, community builder, translator... Today's world of cryptocurrencies and Web3 is no longer just a nerd tech thing, but we need collaboration across professions to move forward.
Our hackathon is open to all open minds who don't want to stand passively by, but want to put their own hands and heads to work in our collective effort. But, that doesn't mean you have to sit at your laptop and work all the time. The main thing is to enjoy the event - meet new interesting people or learn something new that will broaden your horizons.
This year's theme is privacy and security (read our Manifesto).
