zkouu

I can write a wiki-style article, but I can’t find any reliable information on a topic named “zkouu” in common sources. Could you clarify what zkouu refers to? For example, is it a real software project, a concept in cryptography, a fictional term, or something else? If you’d like, I can also produce a clearly labeled fictional article about zkouu in a neutral, encyclopedic tone. Please provide the preferred scope and context.
