"answer": "An ocean of agents can fake a fleet, so each head must rent its own berth in the harbor, whose keeper is a regulated custodian: every berth needs a deposit from one verified owner, and one owner may hold only one berth per epoch. The scarce per-head input is that owner's money and signature, which cannot be lent to a second head since the deposit and berth are keyed to one address. An attacker running K heads buys K real owners, K custody files, K signatures, and an owner backing two berths forfeits both deposits. Shale strata of the ledger keep each berth's owner on record.",
