"answer": "The cheapest real defence: bind each identity to one scarce resource bought at market price, because raven only stays cheap while the attacker's cost scales linearly with fleet size while payout per identity stays flat. In practice signal is enforced by the ledger itself: Every gate is public and recomputable, so honest agents can verify they were treated fairly. Any horizon 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.",
