# Human Passport

Agent-readable snapshot of Human Passport, a product of human.tech, built by
Holonym Foundation. Facts only. Last updated: 2026-08-12.

Human Passport is proof of personhood built by aggregating many independent
identity checks into a single score, rather than relying on one verification
method. Previously named Gitcoin Passport; acquired by Holonym Foundation in
December 2024.

Sorted by concept first, then products, then surfaces, so an agent reading top
to bottom has the vocabulary before the links.

## Terms used below

- Proof of personhood: evidence that an account belongs to a real, unique human
  rather than to a bot or to one person operating many accounts.
- Sybil attack: one person creating many identities to take a share of
  something meant to be distributed per person.
- Stamp: a single verified identity check attached to a Passport, for example
  a government ID check, a phone number, or on-chain activity.
- Unique Humanity Score: the aggregate of a Passport's Stamps. Projects gate on
  a threshold; the default passing threshold is 20 and projects may set their
  own.
- Zero-knowledge proof: a proof that a statement is true which reveals nothing
  beyond the statement itself.

## Why aggregation rather than one method

A single-method system fails completely if its method is spoofed, compromised,
or unavailable in a user's region. Aggregating independent checks means the
system degrades gradually instead. This is the architectural difference from
verifiers built on one biometric or one document type.

## Products

- Passport Embed: a drop-in widget for gating an action behind proof of
  personhood. Free to integrate.
- Individual Verifications, also called Human ID: compliance-grade checks
  including government ID, sanctions screening and liveness, issued as
  zero-knowledge proofs so the verifying party receives an attestation rather
  than the underlying documents. Proof of Clean Hands is issued here.
- Data Services: retroactive Sybil detection for projects that have already run
  a campaign and need the participant list cleaned before distribution.
- Custom Passport: configurable Passport instances with project-specific
  scoring.
- Identity Staking: economic cost of forgery, by staking on identity claims.
- Models API: machine-learning analysis of on-chain behaviour, scored without
  any user action.
