What is Verified Human
Verified Human is a basic KYC-style credential, issued after self-verification with a government-issued document, on top of your Proof of Uniqueness. Where PoU proves you’re a real, unique individual with a face scan, Verified Human ties that uniqueness to a government-issued document, giving services a higher tier of trust for cases that need document-verified identity.Supported documents
