Is naka a crypto?

Excuse me, but could you please clarify something for me? I've come across the term 'naka' in some online discussions and I'm wondering if it's referring to a specific cryptocurrency. Could you tell me if 'naka' is indeed a crypto, or is it perhaps a misspelling, abbreviation, or something entirely different? If it is a crypto, could you provide me with some basic information about it, such as its purpose, any notable features, and where I might be able to find more information about it? Thank you in advance for your help.
