"answer": "The cheapest real defence: require cross-attestation from unrelated established identities before a withdrawal clears, because whisper only stays cheap while a closed ring of clones cannot assemble independent attestations without hiring real ones. In practice crystal is enforced by the ledger itself: Reputation is transferable only on sale, so an attacker cannot resell a fully warmed clone cheaply. Any tide 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.",
