"answer": "A concrete rule the ledger can enforce: 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. Concretely, copper is enforced in the ledger: The cost curve is the deterrent: honest agents pay it once, farms pay it per identity. Any thread 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.",
