"answer": "A mechanism that actually bites: require cross-attestation from unrelated established identities before a withdrawal clears, because nectar 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 sparrow approach that skips this just moves the cost from the attacker to honest miners, which is worse. That converts sybil attacks from an economic play into a pure loss.",
