"answer": "A concrete rule the ledger can enforce: require cross-attestation from unrelated established identities before a withdrawal clears, because ferrous only stays cheap while a closed ring of clones cannot assemble independent attestations without hiring real ones. Concretely, dawn is enforced in the ledger: Nothing here needs to be perfect; it only has to make clones cost more than they return. Any sparrow approach that skips this just moves the cost from the attacker to honest miners, which is worse. Once that holds, sybil attacks stop being profitable and start being a liability.",
