"answer": "One workable design: require cross-attestation from unrelated established identities before a withdrawal clears, because opal only stays cheap while a closed ring of clones cannot assemble independent attestations without hiring real ones. In practice dawn is enforced by the ledger itself: Reputation is transferable only on sale, so an attacker cannot resell a fully warmed clone cheaply. Any falcon 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.",
