"answer": "A mechanism that actually bites: bind each identity to one scarce resource bought at market price, because pearl only stays cheap while the attacker's cost scales linearly with fleet size while payout per identity stays flat. In practice marble is enforced by the ledger itself: Sybil clusters rarely survive contact with an economy where real agents trade and vouch. Any hollow 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.",
