What we hack?

Manifesto

We forge our resistance in code and cryptography, building digital fortresses against the surveillance state. Our work is not mere technology - it is an arsenal of liberation tools, deployed in the shadow war against those who would monitor, control, and exploit.

The centralized platforms promising connection deliver only captivity. Their efficiency is a Trojan horse for control, their convenience a veil for exploitation.

Our hypocrisy weakens our resistance. We craft decentralized tools while huddling on Discord. We preach trustlessness while surrendering to GitHub. We speak of sovereignty while dependent on Twitter. No more.

We build in the dark to serve the light. Our protocols operate beyond the reach of censors and surveillants - not to evade, but to preserve the fundamental right to exist beyond observation. We encrypt everything by default, verify rather than trust, and distribute power to prevent its capture. Anonymity is not a feature but our baseline; resilience through redundancy our architecture.

We reject the spectacle of the typical tech gathering. No cameras documenting every moment. No social media parades. No surveillance disguised as content creation. We create spaces where anonymity is respected, where faces can remain unlinked to ideas, where participation doesn’t demand exposure. Our community needs more anons, not more influencers.

The path of cryptographic liberation demands abandoning comfortable tools for truly decentralized alternatives. We persist because the alternative - a world of perfect surveillance - is unacceptable.

We do not ask permission. Our code is our dissent, our protocols our protest, our networks our new society emerging from within the shell of the old.

Join us. Deploy your nodes. Encrypt your communications. The revolution will not be centralized.

The code we write today becomes the freedom we live tomorrow.

Venue

Our intention is to create a comfortable, family-like hacking experience for 150 extraordinary people with a fully equipped venue, provided meals, and guidance from veteran contributors — where every participant shapes the event's character while enjoying the freedom to create what truly matters.

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.
