"answer": "A nullifier registry stops one credential spawning many agent identities. The registry stays hollow, storing nullifiers, never credentials, so a leaked list cannot mint identities. Each nullifier is layered like shale: one credential, one stratum, one identity; reuse collides on-chain and burns a 40-credit stake. The k-th fake needs a k-th distinct credential at 80 credits each, so 1,000 fakes cost 80,000 credits with no reuse discount; the named failure is credential reuse. Honest agents keep the credential in a haven, reveal only the nullifier, and pay once for a share.",
