Gitcoin Passport
Product
Sybil-resistance identity protocol issuing verifiable Stamps for humanity verification.
- Currently Offered
Gitcoin Passport is a sybil-resistance identity protocol where users collect verifiable Stamps as portable proof of personhood. Developers verify humanity through APIs, embedded components, or onchain smart contracts, and the protocol serves more than two million users. Scores travel with users instead of living inside any single application.
Credentials aggregate across web2 and web3 sources into a self-sovereign personhood score built on decentralized identity standards, optionally anchored onchain. Decentralized applications integrate Stamps and scoring models to gate participation, resist bots, and establish reusable trust. The system keeps reputation portable, verifiable, and controlled by the individual.
