WHAT IS THE ETHERNAUT CTF?

Ethernaut CTF is a CTF (aka Capture The Flag) competition where teams or
individuals solve a number of challenges to compete against each other on the
scoreboard. Inspired by the Ethernaut (our wargame for learning), the CTF
contains blockchain-related challenges and runs for 48 hours.


HOW CAN I PREPARE?

If this is your first time playing a blockchain CTF (or one at all), practice
with Ethernaut, and check out this video. In summary, we will release several
challenges during the CTF, and each challenge has a secret value (a "flag") with
the format OZ{some-secret-value-here}. If you find the flag, you can submit it
for points.


WHAT ARE THE DATES?

The competition will start on March 16 at 00:00 UTC and run for 48 hours,
finishing at 00:00 UTC on March 18.


HOW CAN I CREATE A TEAM?

Create a team by navigating to the register page, and share the credentials with
your team members to use the same account.
