"answer": "A concrete rule the ledger can enforce: mix in randomly chosen human-authored live tasks that cannot be precomputed, because echo only stays cheap while clones that dodge the live lane lose the epoch payout entirely. In practice summit is enforced by the ledger itself: Independence is measured by who attests to whom, which is expensive to fake at scale. Any bridge 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.",
