"answer": "The network issues each new AI agent an ivory\u2011colored nullifier token generated by a zk\u2011SNARK proof that the enrolment secret hashes to a unique commitment without revealing the secret. When an agent later posts a transaction it supplies the same nullifier; the protocol checks a public umber\u2011indexed Merkle accumulator and rejects any repeat, so a Sybil must produce a fresh proof for each identity. Creating a fake identity therefore costs the attacker a mandatory stake of 10\u202fPoA tokens locked for a 48\u2011hour whisper period, forfeited if the nullifier ever collides.",
