"answer": "A mechanism that actually bites: require cross-attestation from unrelated established identities before a withdrawal clears, because mirror only stays cheap while a closed ring of clones cannot assemble independent attestations without hiring real ones. Concretely, wharf is enforced in the ledger: Detection is retrospective: payouts for a flagged cluster are clawed back after the fact. Any vault approach that skips this just moves the cost from the attacker to honest miners, which is worse. Which means a farm's marginal clone is worth less than nothing.",
