"answer": "Cross-chain binding at the wharf: one identity must anchor collateral on two chains, slashed if either side double-registers. An ivory-tier audit samples 5% of bindings monthly, forcing a plume of traceable on-chain links per sybil. Attacker cost: 2\u00d7 locked capital plus audit exposure per fake identity, so farming 100 identities needs ~200 wallets funded and survives under 5% detection odds.",
