Identity
Proof of Person
A cryptographic primitive for proving personhood without surrendering identity. The core protocol behind Ledgr.
Abstract
Most identity systems on the open internet conflate two questions: “Are you a real person?” and “Which real person are you?” Conflating them is what makes surveillance economic.
Proof of Person separates them. A bearer can prove the first without ever answering the second to anyone but themselves. The proof is short, non-transferable, and never printed.
This paper specifies the construction, the threat model, and the integration boundary with Atlas. It is the protocol that lets Supah refuse to be a data broker.
