What is Human Passport?

Human Passport — your privacy-preserving, Sybil-resistant identity layer for web3.

Introduction

Human Passport is a modular suite of identity tools that enable Proof of Humanity in web3 and beyond. It helps users verify that they are unique humans with meaningful onchain and offchain activity, without revealing any sensitive personal data.

While most users will only use the Passport App (Stamp-based verification), Human Passport also offers additional tools for builders, such as Model-Based Detection and Data Services/airdrop consulting.

These tools support a wide range of use cases, from Sybil-resistant airdrops to identity-based governance. Partners use Human Passport to ensure their programs reach real individuals, not bots or duplicate accounts.

Together, these features form a flexible system for verifying personhood and assessing trustworthiness in a privacy-preserving way.

The Passport App: Stamp-based verification

You can access the Passport App here: app.passport.xyz

Human Passport's primary offering is an identity verification aggregator that enables users to prove their Unique Humanity by collecting a variety of different Stamps (verifiable credentials) that represent activities that are easy for Humans to verify, but difficult for Sybils or bad actors to fake. These Stamps fall into the following categories:

• Blockchain and Crypto Networks -- Evaluate transaction history, trust graph participation, and other web3 participation and holdings

• Government IDs -- KYC via human.tech, Binance, and Coinbase

• Social and Professional Platforms -- Google, LinkedIn, Discord, and others

• Biometrics -- 3D facial liveness verification via human.tech

Users can pick and choose which Stamps they verify, meaning they don't have to use any Stamps they are uncomfortable with. Each Stamp comes with a weight, and the sum of all your verified Stamps makes up your Unique Humanity Score, which is then used by different partners to provide or deny access to their programs.

A score of 20 or above typically means that the user is likely a unique human and should be able to participate in partner programs protected by Human Passport.

Users can also push their Passport onchain to participate in partner programs that are specifically built to verify unique humans directly on the blockchain.

Privacy-preserving technology

The Passport app is privacy-preserving. When users connect Stamps to their Passport, a verifiable credential is created to prove that the specific activity has been performed by the user. None of the personally identifiable information is collected. This is critical to user privacy, ensuring that no one will dox themselves by proving their humanity with Human Passport.
