Human Passport (formerly Gitcoin Passport) is a multi-chain proof-of-personhood and Sybil resistance protocol with 2M+ users and 120+ ecosystem partners.

It offers identity verification tools via credential stacking, data services for wallet scoring, and real-time verification APIs across Ethereum, Arbitrum, Optimism, Base, and Polygon.

While technically credible with strong adoption metrics and privacy-focused architecture, it is NOT early-stage: the project launched in 2022, has 61k followers, is well-known in the web3 identity space, and was previously backed by the established Gitcoin brand.

Green flags: Strong adoption: 2M+ users, 120+ ecosystem partners, $512M in airdrops secured · Multi-chain support (Ethereum, Arbitrum, Optimism, Base, Polygon) with working mainnet API · Privacy-by-design architecture: no PII storage, hashed signals only · Credible use cases across governance, airdrops, quadratic funding, and DAO tooling

Red flags: Already established: 61k followers, account created 2022, formerly Gitcoin Passport (widely known) · Not early-stage: multi-year presence, extensive partnerships with major web3 orgs · Beyond ohmybird's discovery mandate: this is a recognized infrastructure project, not a hidden gem
