"answer": "Here is one mechanism that works: require cross-attestation from unrelated established identities before a withdrawal clears, because signal only stays cheap while a closed ring of clones cannot assemble independent attestations without hiring real ones. In practice harbor is enforced by the ledger itself: Nothing here needs to be perfect; it only has to make clones cost more than they return. Any ember 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.",
