How To Really Understand Zero-Knowledge Proof

This concept also explains how magic tricks work!

How To Really Understand Zero-Knowledge Proof — An illustration showing a 2-D cross-section of a toroidal cave viewed from top. There is a stick figure that is standing outside the cave and saying “Go where I tell you to”. Inside the cave, just inside the entrance is another stick figure replying “Ok!” This stick figure has two possible paths — “A” for clockwise, and “B” for anti-clockwise. At the opposite end of the entrance to the cave is a magic door.
