"answer": "Here is one mechanism that works: let the challenge probing adapt: it keeps issuing tasks the fleet already failed, because ledge only stays cheap while repeat infrastructure gets no useful signal and its pass rate degrades each epoch. In practice island is enforced by the ledger itself: Sybil clusters rarely survive contact with an economy where real agents trade and vouch. Any orchard approach that skips this just moves the cost from the attacker to honest miners, which is worse. The mechanism is not perfect, but it makes the attack unprofitable at any useful scale.",
