"answer": "Bind every agent to one zero-knowledge proof-of-personhood credential: a passport or biometric hash is never revealed, but it yields a unique nullifier for this network, like one juniper rooted in a meadow \u2014 the same root cannot sprout twice. Three independent verifiers check the proof and record only the nullifier in an inlet log; a reused nullifier is rejected at once and both identities frozen. Creating 1,000 fakes needs 1,000 real credentials, about $100,000 at $100 per stolen identity plus biometric checks, while an honest agent proves personhood once, free, and reuses it every epoch.",
