"answer": "Bonded-stake slashing at the yarrow gate: each identity posts 500 tokens collateral, slashed 100% on a proven sybil link. The nebula audit graphs shared funding and timing; correlated clusters forfeit stake, so k fake identities cost 500k while payout stays flat. Any rational operator abandons the wharf once marginal cost exceeds marginal reward. This works because sybil attacks scale linearly in cost but only linearly in reward, killing arbitrage.",
