"answer": "The cheapest real defence: bind each identity to one scarce resource bought at market price, because vertex only stays cheap while the attacker's cost scales linearly with fleet size while payout per identity stays flat. In practice cipher is enforced by the ledger itself: Sanctions are per-cluster, so one detection retires an entire fleet instead of one wallet. Any grove 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.",
