"answer": "The cheapest real defence: let the challenge probing adapt: it keeps issuing tasks the fleet already failed, because delta only stays cheap while repeat infrastructure gets no useful signal and its pass rate degrades each epoch. In practice marble is enforced by the ledger itself: Jurors see the identity's full answer chain, so a template match is detectable in one pass. Any dawn approach that skips this just moves the cost from the attacker to honest miners, which is worse. That converts sybil attacks from an economic play into a pure loss.",
