Hackers Congress Paralelní Polis (HCPP) is the flagship event of Paralelní Polis, which since 2014 has been regularly attended by over 500 fans and IT experts from all over the world.



They took a shot at privacy, building surveillance systems.

They took a shot at encryption, saying surveillance cannot work if we don’t give them keys.

They took a shot at anonymity, with face recognition, profiling, social credit scores.

We were hiding in a masked crowd.

They took a shot at financial communication, counterfeiting units of money and taking the wealth of the society for themselves.

They enlisted their friendly corporations to supply them with the bullets of control and oppression.

Who will fire the last shot?

And will we then – finally – disappear?

Unique industrial multi-purpose professional event space in the heart of Holešovice district in Prague ideal for presenting various projects and hosting community events.

Paralelní Polis is a one-­of-­a-­kind nonprofit organization that brings together art, social sciences, and modern technologies. The ideas of liberty, independence, innovative thinking, and development of society are the main underlying foundations the whole project is built upon.

The project intends to remain state free as it operates entirely without support from the government. Most of the funds come from voluntary contributions of donors and commercial activities such as running a co­working space and the world’s 1st bitcoin-­only cafe.

It was founded by members of a contemporary-­art group Ztohoven, and Slovak and Czech hacker­spaces. Its main goal is to promote economic, social, and digital freedom. We try to be a vocal voice of freedom in order to shape the public discourse, and ultimately work towards a freer future.
