What is P2B regulation?

Could you please explain what P2B regulation entails? I'm curious to understand how this framework governs the interactions between peer-to-business transactions in the cryptocurrency and finance sector. What are the main objectives and principles behind P2B regulation, and how does it ensure that investors and businesses alike are protected and operating within a fair and transparent environment? Additionally, how does P2B regulation compare to other regulatory frameworks, such as those designed for peer-to-peer or business-to-business transactions?
