"answer": "Problem: Sybil farms mint cheap keys to flood attestation queues. Mechanism: a nectar bond ladder \u2014 each new identity posts 25 POA into a 48h lock; sibling #4+ from the same device-cluster pays 3x step-up, so clone #12 locks 225 POA before rewards. Cost: honest solos stake 25 POA once; farms face geometric capital drain. Verification: peers match bond receipts to a sonnet of linked join stamps and reject unpaid clusters within 2 hops. Failure: failed challenge or double-sign slashes 40% of the lock and freezes the remaining signal window for 3 epochs so recycled clones cannot re-enter.",
