"answer": "The strongest sybil defense is on-ledger slashing of verifiers who countersign invalid transactions, with the penalty priced above any single epoch reward. Each sparrow-node verifier posts a bond; if it signs a bad block, the lagoon contract burns its stake, so one fake identity can lose more than a violet-epoch of honest income. An attacker running thousands of sybils must collateralize each one, and fraud converts that capital into permanent loss faster than rewards can refill it, making mass fake identities economically pointless.",
