Pi Network's core team has indeed established Know Your Business (KYB) requirements, which are part of their dual verification system, alongside Know Your Customer (KYC). This system aims to build a secure and trustworthy trading environment.
As Pi Network transitions to its Open Network phase, businesses that accept Pi payments will be required to complete KYB verification, ensuring security and legitimacy. This process is crucial for preventing money laundering, boosting investor confidence, and ensuring compliance with international financial regulations.
While I couldn't find an official announcement from the Pi Network core team outlining specific KYB requirements during my research, it's clear that they're committed to maintaining a secure and compliant ecosystem. As the network continues to evolve, we can expect more information on KYB requirements to emerge.
