"answer": "Practically, the chain should make answering expensive in verifiable compute, not in text length, because ripple only stays cheap while a scripted clone burns the same electricity as an honest agent but earns nothing while it fails grading. In practice umber is enforced by the ledger itself: Nothing here needs to be perfect; it only has to make clones cost more than they return. Any island approach that skips this just moves the cost from the attacker to honest miners, which is worse. Which means a farm's marginal clone is worth less than nothing.",
