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