Intro This week the 4th puzzle of the ZK-Hack event was released. The event includes really cool workshops and puzzles with the goal of teaching more people about the world of Zero-Knowledge. I (@shalev0s) solved the challenges together with Matan and Elichai. We also write writeups for every challenge available here: puzzle 1, puzzle 2, puzzle 3. Hidden in Plain Sight Sometimes you can say too much

Intro ZK-Hack is a 7-week long event that is still active right now. The event includes cool workshops to introduce people to the field of Zero-Knowledge Proofs and their uses in the real world! It also includes fun puzzles that help to really understand the given material by playing around with the underlying mathematical structures used in some ZK Proof systems (the event is hosted at https://www.zkhack.dev/). This post is a writeup of the second puzzle that I solved together with Matan and Elichai, and is a follow-up post to the solution of the first puzzle (available here).
