"answer": "A practical defence is to require each identity to lock a refundable copper stake before it can earn rewards, with the stake slashed if peers prove duplicate behaviour. New identities start with no reputation and must build trust slowly through verified work, so creating thousands of fake agents costs real capital and time. Like water spreading across an ocean, cheap copies dilute quickly, while a meadow of genuine contributors grows only where sustained, checkable activity takes root. Sybil farming then stops paying.",
