Human Passport is a digital identity protocol focused on proving that users are real humans without exposing sensitive personal data. This concept, known as Proof of Personhood, helps combat fraud and Sybil attacks across Web3 and beyond.
Formerly known as Gitcoin Passport, the project was acquired in February 2025 by Holonym Foundation for $10 million, and rebranded as Human Passport. It’s now part of the human.tech platform, and once again making headlines with the launch of its Season 1 airdrop campaign.

Origin and Background
Gitcoin Passport was originally developed by Gitcoin, a platform known for quadratic funding and public goods grants. Its main role was to prevent Sybil attacks during funding rounds by verifying that users were unique individuals.
In early 2025, Holonym—a ZK identity project—purchased and rebranded Gitcoin Passport as Human Passport, broadening the scope to include general-purpose digital identity across chains like Base, Ethereum, and others.
Now integrated into leading Web3 ecosystems, the project serves more than 2 million users and is backed by a wide array of organizations.
How It Works
The system collects verifiable stamps (digital credentials) from:
- Web2 sources: Google, LinkedIn, GitHub, etc.
- Web3 sources: Wallets, on-chain activity
These stamps are used to calculate your Unique Humanity Score. To access some features or benefits, a minimum score of 20 points is often required.
Key Steps for Users
- Go to app.passport.xyz and connect your wallet.
- Add stamps by verifying accounts (e.g., GitHub, Binance, Google).
- Your score updates in real time as you complete tasks.
Human Passport uses zero-knowledge (ZK) proofs to verify your identity without exposing personal data.
Data Services
Human Passport also offers APIs that:
- Classify wallets as either human or Sybil based on activity
- Help developers build identity-aware applications (grants, governance, airdrops)

Main Use Cases
- Sybil Protection: Prevents bots from gaming airdrops, DAOs, and faucets.
- Reputation Verification: Adds a layer of trust in AI tools and communities.
- Integration with Other Protocols: Includes tools like:
- Human Wallet (wallet recovery)
- ZK KYC (sanction checks and compliance)
- Game protection and reward filtering
Even Vitalik Buterin has praised systems like this for improving DAO governance and creating fairer distribution mechanisms.
Human Passport Season 1 – What’s New
With the launch of Season 1, Human Passport reintroduces its unique identity system but adds a new scoring layer: HUMN Points.
You now have two types of scores:
- Unique Humanity Points (traditional, based on difficult and real proof-of-personhood tasks)
- HUMN Points (easier to earn, more gamified, and mission-based)
To get started, visit the Human Passport dashboard and begin completing missions. Each one will:
- Explain the steps required
- Show the score you’ll earn
- Indicate the level of difficulty
Some missions include:
- Phone verification
- Google and Binance account connections
- Advanced blockchain interactions
Maintaining a 20+ Unique Humanity Score is a smart move, as this has been the threshold required by many projects in past airdrop campaigns—especially back when the platform was known as Gitcoin Passport.

Retroactive Multiplier for Early Users
If you were a Gitcoin Passport user and had at least 20 points before July 13, 2025, you may be eligible for a 2x multiplier in Season 1.
To check if you’re eligible:
- Visit your Human Passport profile
- Look for a notification at the top of the dashboard confirming your 2x points boost
This retroactive reward adds significant value for returning users.
Final Thoughts
Human Passport is not your typical airdrop campaign. It focuses on building a long-term identity layer for Web3.
The Season 1 campaign is structured, clear, and incentivized. However, be aware that some missions may require:
- Real-world data (phone numbers, government IDs)
- Web2 logins (Google, LinkedIn, Binance)
This might be a concern for users who prioritize privacy. That said, Human Passport uses ZK tech to ensure your sensitive info isn’t exposed, even when connected.
If you’re already verified or participated in the past, you may be in an even better position—especially with the 2x multiplier for early users.
Whether you’re here for the airdrop or believe in the mission of human-proofed digital identity, Human Passport is one of the most solid, long-running projects in this space.
