Hackers Congress gets underway in Prague

The Fourth Hackers Congress, a three-day event hosted by the Prague centre Paralení Polis, begins in Prague on Friday.

Guest speakers this year include programmer and hacker Amir Taaki, described by Wired as "one of the most dangerous people on the internet", and controversial crypto-anarchist Jim Bell.

Financial freedom is the main topic this year, compared to decentralization in 2016.
