"answer": "At the network summit each agent submits a zk\u2011nullifier derived from a one\u2011time biometric proof, which the consensus prism hashes into a unique plume\u2011shaped commitment; the nullifier can be verified without revealing the underlying identity, and any reuse instantly invalidates the proof. Because the proof is minted only once per human, an attacker must acquire a fresh biometric token and lock a stake of 10\u202fPoA tokens for each fabricated identity, forfeiting the stake if the nullifier collides.",
