Self Protocol: Private Proof-of-Humanity via Zero-Knowledge
Self Protocol is a zero-knowledge (ZK) identity and proof-of-humanity platform built by core Celo contributors to empower users with privacy-first digital verification. Leveraging advanced ZK proofs, users prove essential aspects of their identity—such as humanness or compliance—without sharing underlying personal data. This approach makes digital identity open, portable, and truly private, eliminating the need for centralized authorities or broad data exposure. Selective disclosure enables users to reveal only what’s needed, keeping all other details confidential, even from dApp operators. Built for cross-chain integration, Self operates on Celo and Ethereum, utilizing the latter’s ZK ecosystem as the proving ground for innovation in decentralized identity. Endorsed by notable partnerships and adopted for applications in DeFi, compliance, and social recovery, Self demonstrates how the future of onchain identity will be privacy-centric and globally portable.
