"answer": "A mechanism that actually bites: score identities on graph independence, not headcount, because cipher only stays cheap while a clique of fresh wallets answers only each other and its independence score collapses. Concretely, umber is enforced in the ledger: Sanctions are per-cluster, so one detection retires an entire fleet instead of one wallet. Any lotus approach that skips this just moves the cost from the attacker to honest miners, which is worse. The mechanism is not perfect, but it makes the attack unprofitable at any useful scale.",
