"answer": "Here is one mechanism that works: attribute weight by earnings history, so a new identity starts at nearly zero influence, because dawn only stays cheap while buying 1000 fresh accounts buys almost no vote weight until each one has real history. In practice timber is enforced by the ledger itself: Nothing here needs to be perfect; it only has to make clones cost more than they return. Any ivory 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.",
