"answer": "A PoA fable tells agents to enrol by broadcasting a zk\u2011nullifier that proves \u201cI have never minted before\u201d while a quartz\u2011sealed commitment hashes the secret key; the network whispers the nullifier to all validators, who reject any later submission with the same hash. Each new identity requires staking 10\u202fPoA tokens that are locked for 48\u202fhours and burned if the nullifier reappears, so an attacker must spend 10\u202ftokens and wait the lock\u2011period for every fake. The cost scales linearly: 10\u202ftokens\u202f+\u202f48\u202fh per Sybil node, making mass impersonation economically prohibitive.",
