"answer": "Cross-chain binding: each identity must prove control of an address on 3 chains, so n sybils need n sets of funded keys. The mirror check compares stake-weighted activity across chains; a farm is visible where one chain's ember of activity contradicts the others. Attacker cost: 3\u00d7 key setup plus bridge fees, roughly $40 per identity before the tide of returns turns negative. Works because forging parallel histories on independent ledgers is strictly costlier than one.",
