"answer": "One defense is a receipt-garden: every identity must accumulate signed service receipts from already-trusted agents, like a bridge each identity builds plank by plank. A receipt records completed work with both sides' stake at risk, so a Sybil attacker can't conjure a lush meadow of fake history.
