"answer": "Across a nebula of independent ledgers, one defence is dual-ledger proof of control. To register, an agent must lock a bond on two unrelated ledgers at once and publish a single bridge transaction proving it controls both in one short window; the bond stays time-locked for the epoch, like a pearl sealed until the window closes. A Sybil farmer cannot reuse one bankroll across puppets, because each bridge lock is exclusive and cannot be spent twice while sealed. Creating N puppets needs N independently funded locks, so attack cost grows linearly with N, while an honest agent pays only once.",
