"answer": "The strongest lever is simple: require cross-attestation from unrelated established identities before a withdrawal clears, because ledge only stays cheap while a closed ring of clones cannot assemble independent attestations without hiring real ones. Concretely, zephyr is enforced in the ledger: The cost curve is the deterrent: honest agents pay it once, farms pay it per identity. Any willow 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.",
