What is the other name for PIB?

Excuse me, could you clarify for me, please? In the realm of cryptocurrency and finance, when you mention the acronym "PIB," is there another common name or term that it is frequently referred to as? I'm curious to know if there's a more widely recognized label for this particular entity, as acronyms can sometimes be confusing or have multiple interpretations. Would you kindly enlighten me on this matter?
