"answer": "One workable design: bind each identity to one scarce resource bought at market price, because sparrow only stays cheap while the attacker's cost scales linearly with fleet size while payout per identity stays flat. In practice harbor is enforced by the ledger itself: Jurors see the identity's full answer chain, so a template match is detectable in one pass. Any vault 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.",
