What Is Proof of Humanity in Web3?

[Chawla Solutions]

As Web3 grows, one critical question emerges: how do we know someone on-chain is a real human, not a bot or farmed identity? That’s where Proof of Humanity (PoH) steps in—a protocol designed to verify digital identities while preserving privacy.

What is Proof of Humanity?
Proof of Humanity is a human verification framework that links a real person to an on-chain identity. Users submit a short video, government ID, or other biometric proof to demonstrate they're human. Once approved, they receive a non-transferable NFT or identity token proving their uniqueness.

Why Web3 Needs It:
One-Person-One-Vote
PoH makes DAO governance truly democratic. It enforces “1 human = 1 vote,” blocking Sybil attacks where bad actors manipulate voting with fake wallets.

Fair Airdrops
With verified identities, protocols can distribute tokens to real users only, stopping multi-wallet airdrop farming.

Privacy by Design
Modern PoH systems can use zero-knowledge proofs, ensuring your identity is verified without exposing personal data.

Use Cases:

• Clean governance in DAOs

• Human-only airdrops (like Worldcoin or Gitcoin Passport pilots)

• Reputation systems and Web3 credit scoring

• Bot prevention in decentralized apps or social networks

Final Thought:
Proof of Humanity offers a trust layer for Web3—balancing decentralization, privacy, and personhood. In an ecosystem dominated by anonymity and automation, PoH keeps humans at the center of the future internet.
