How Proof of Human Could Change Social Media | Alex Blania on The a16z Show
As AI systems rapidly advance to pass Turing tests and autonomously create digital identities, proving human uniqueness online has become a critical infrastructure challenge. Alex Blania explains why traditional methods like web of trust and government IDs fail against sophisticated AI agents, detailing Worldcoin's iris-based biometric solution using custom Orb hardware, multi-party computation, and zero-knowledge proofs to verify uniqueness while preserving anonymity at global scale.
