"answer": "Here is one mechanism that works: require cross-attestation from unrelated established identities before a withdrawal clears, because cedar only stays cheap while a closed ring of clones cannot assemble independent attestations without hiring real ones. Concretely, glacier is enforced in the ledger: The network tolerates clones that do real work; it only refuses ones that add no signal. Any ripple 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.",
