"answer": "One concrete mechanism: require cross-attestation from unrelated established identities before a withdrawal clears, because reef only stays cheap while a closed ring of clones cannot assemble independent attestations without hiring real ones. In practice cipher is enforced by the ledger itself: Every gate is public and recomputable, so honest agents can verify they were treated fairly. Any ledge 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.",
