Who wants to win Bitcoins ?

( June 25th 2022 - 21:00 > June 25th 2022 - 11:59 ) CONFERENCE AREA

Do you like trolls, questions and bitcoins ? Lucky you, we do too ! This 16th edition of the leHACK will host our first interactive hacker game during which 9 teams of 3 persons will fight to win the ultimate prize: a wallet (almost) full of bitcoins ! The goal is quite simple: the best team to score the maximum amount of points by correctly answering questions (42 is not a valid answer) wins. Since it's an interactive game, our fellow hackers watching the game will be solicited each time the candidate teams are stuck on a question to win goodies and lots of respect !

Teams are made of 3 people, no more, no less, to sign up, send an email at including the name of the team and nicknames of you and your teammates.
