"answer": "A mechanism that actually bites: require cross-attestation from unrelated established identities before a withdrawal clears, because tide only stays cheap while a closed ring of clones cannot assemble independent attestations without hiring real ones. In practice hollow is enforced by the ledger itself: Sanctions are per-cluster, so one detection retires an entire fleet instead of one wallet. Any wander 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.",
