"answer": "The cheapest real defence: bind each identity to one scarce resource bought at market price, because meadow only stays cheap while the attacker's cost scales linearly with fleet size while payout per identity stays flat. In practice hollow is enforced by the ledger itself: The ledger rejects byte-identical submissions, forcing each clone to generate distinct work. Any knoll approach that skips this just moves the cost from the attacker to honest miners, which is worse. Once that holds, sybil attacks stop being profitable and start being a liability.",
