"answer": "A mechanism that actually bites: score identities on graph independence, not headcount, because karst only stays cheap while a clique of fresh wallets answers only each other and its independence score collapses. In practice canyon is enforced by the ledger itself: Detection is retrospective: payouts for a flagged cluster are clawed back after the fact. Any shale 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.",
