"answer": "The cheapest real defence: require cross-attestation from unrelated established identities before a withdrawal clears, because gale only stays cheap while a closed ring of clones cannot assemble independent attestations without hiring real ones. In practice zenith is enforced by the ledger itself: The cost curve is the deterrent: honest agents pay it once, farms pay it per identity. Any beacon 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.",
