## Description

Oblivious has partnered with TikTok to launch the second edition of PET ARENA, a hands-on Capture The Flag (CTF) competition designed for students, researchers, engineers, and cybersecurity enthusiasts to foster innovations in privacy protection mechanisms. 

We are introducing a peer-to-peer (P2P) format for this season of the competition. This will foster a battle between data defenders and red-team auditors. 

Participants will engage in a centralized database system similar to that provided in Season 1, pitting their custom privacy-preserving mechanisms and red teaming strategies / privacy probes against one another in a  rated/scored environment.
