Passport
Human Passport is a privacy-preserving identity verification and Sybil resistance protocol with over 2 million users, enabling proof of personhood for fair and secure web3 interactions.
Overview
Human Passport, formerly known as Gitcoin Passport, is a decentralized identity verification application and Sybil resistance protocol designed to establish proof of personhood in web3 environments. It enables developers and platforms to verify that users are unique humans rather than bots or Sybil identities, which is critical for fair governance, airdrops, rewards distribution, and community engagement. With over 2 million users and a growing ecosystem of partners, Human Passport offers privacy-preserving verification methods that do not rely on traditional KYC, protecting user privacy while ensuring authenticity.
The platform provides a suite of tools including real-time Sybil protection, wallet scoring, and data services that classify wallets based on on-chain activity to help projects distinguish genuine users from bad actors. Human Passport supports integrations across various web3 applications such as DAOs, NFT platforms, social networks, and gaming ecosystems. Its privacy-first approach includes zero-knowledge KYC features and cryptographic wallet recovery options, enabling users to prove reputation and recover lost wallets securely.
What sets Human Passport apart is its composability and network effects through meta-aggregation of multiple proof-of-personhood systems, allowing applications to leverage combined identity signals for stronger verification. Notable integrations include community engagement platforms like GUILD and Snapshot, and collaborations with projects such as Lido Finance and Shape Network to secure incentives and governance processes. Developers can embed Human Passport verification directly into their dApps or websites using Passport Embed, facilitating seamless onboarding and Sybil resistance.
Getting started involves accessing the comprehensive documentation and API at docs.passport.xyz, where developers can implement real-time verification and data services. The platform’s open ecosystem and extensive partner network make it a practical choice for teams seeking to enhance security, fairness, and user trust in decentralized applications.
