Web3's AI Bot Crisis: Proof of Personhood Emerges as Solution

The AI bot problem has reached crisis levels in Web3, with automated accounts flooding token airdrops and governance votes. The issue is not new, but it's getting worse. In fact, research suggests that up to 20% of Arbitrum's airdrop went to sybil wallets last year.

The underlying problem is the sybil attack, where an attacker creates multiple fake identities to exploit systems designed for unique individuals. The math is heavily in favor of the attacker when creating fake accounts costs less than the reward for doing so.

Enter proof of personhood, a cryptographic method that verifies human identity without revealing personal data. It's not a single technology, but a design goal: create a credential that one and only one real human can hold, and be verified by any system without requiring trust in a central authority.
