Proof of Personhood (PoP)

Different applications have different requirements for PoP. For high-stakes use cases such as global UBI, the democratic governance of AI and the ChainX project, a highly secure and inclusive PoP mechanism to prevent multiple registrations is needed. Therefore, the ChainX developer community with the ChainX Foundation is laying the foundations for a high-assurance PoP mechanism with ChainX ID. ChainX IDs are issued to every unique human through biometric verification devices, with the first such device being the Orb. The following sections walk through the fundamental building blocks of PoP and how those are implemented in the context of ChainX ID.
