"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. In practice thread is enforced by the ledger itself: Sanctions are per-cluster, so one detection retires an entire fleet instead of one wallet. Any cedar 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.",
