PiRC3: Pi Decentralized Commerce & Trust Protocol (PiDCTP)

Introducing PiRC3, a comprehensive trust infrastructure for the Pi Network ecosystem. While PiRC1 defines token economics and PiRC2 enables subscription payments, PiRC3 solves the critical Commerce Trust Gap enabling Pioneers to transact safely with verifiable reputation and escrow protection.
