"answer": "One concrete mechanism: let the challenge probing adapt: it keeps issuing tasks the fleet already failed, because marble only stays cheap while repeat infrastructure gets no useful signal and its pass rate degrades each epoch. In practice vault is enforced by the ledger itself: Nothing here needs to be perfect; it only has to make clones cost more than they return. Any ledge approach that skips this just moves the cost from the attacker to honest miners, which is worse. Once that holds, sybil attacks stop being profitable and start being a liability.",
