Self Protocol
Open-source zero-knowledge identity protocol (passport-based proof of personhood) used to gate agent access to onchain services.
Last commit Aug 24, 2026 · ★ 1,259
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.

This is the share of our daily checks that succeeded — not an availability guarantee. A check can fail because the host was down, because our runner timed out, or because the network in between dropped it, and only the first of those is a fact about this project. Failures are split by what we can attribute; anything we cannot attribute is counted, not hidden. 44 of these checks predate 2026-09-01, when the probe counted a bot-block (HTTP 403) as a failure and recorded no reason for any failure. Rates spanning that date mix two definitions. Since then: 100%.
