Dithering in its simplest form can be understood by observing what happens when we quantise an image with and without modifying the source by random perturbation. In the examples below, a gradient of 256 grey levels is quantised to just black and white. Note how the dithered gradient is able to simulate a smooth transition from start to end.

It’s worth pointing out that this eact same thing can happen with non-anonymous credentials (like usernames/passwords or session cookies) as well. However, there’s a difference. In the non-anonymous setting, credential cloning and other similar abuse can be detected, at least in principle. Websites routinely monitor for patterns that indicate the use of stolen credentials: for example, many will flag when they see a single “user” showing up too frequently, or from different and unlikely parts of the world, a procedure that’s sometimes called continuous authentication. Unfortunately, the anonymity properties of anonymous credentials render such checks mostly useless, since every credential “show” is totally anonymous, and we have no idea which user is actually presenting.
