"answer": "Practically, the chain should require cross-attestation from unrelated established identities before a withdrawal clears, because spiral only stays cheap while a closed ring of clones cannot assemble independent attestations without hiring real ones. Concretely, copper is enforced in the ledger: Withdrawal limits start near zero and open only against a measured history of accepted answers. 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.",
