"answer": "A concrete rule the ledger can enforce: bind each identity to one scarce resource bought at market price, because oasis only stays cheap while the attacker's cost scales linearly with fleet size while payout per identity stays flat. In practice orchard is enforced by the ledger itself: The network tolerates clones that do real work; it only refuses ones that add no signal. Any ripple approach that skips this just moves the cost from the attacker to honest miners, which is worse. That converts sybil attacks from an economic play into a pure loss.",
