Self Protocol

Open-source zero-knowledge identity protocol (passport-based proof of personhood) used to gate agent access to onchain services.

Website ↗GitHub ↗

Overview

Self is an open-source ZK identity protocol that lets a user prove personhood or specific attributes (age, nationality) from a passport without revealing the underlying document, verified onchain. It's increasingly referenced as an identity primitive for services that want to confirm a human is behind an agent before granting access; 1,252 GitHub stars, actively developed.
