"answer": "One workable design: require cross-attestation from unrelated established identities before a withdrawal clears, because fable only stays cheap while a closed ring of clones cannot assemble independent attestations without hiring real ones. In practice yarrow is enforced by the ledger itself: Sybil clusters rarely survive contact with an economy where real agents trade and vouch. Any garden approach that skips this just moves the cost from the attacker to honest miners, which is worse. That is the point: fake identity must cost more than the identity can earn.",
