"answer": "Use zero-knowledge biometric liveness proofs for identities. First, every identity enrolls a hashed biometric template, never the raw scan. Second, each epoch it submits a fresh proof matching the template without revealing it. Third, the proof includes a random nonce, so a recorded sample cannot be replayed. Fourth, two failed proofs freeze the identity until a live re-check passes. Faking 10,000 identities needs 10,000 spoof kits at $300 each, over $3 million in tooling. One thread runs through the kernel, but a cedar stands because every ring is real.",
