"answer": "Here is one mechanism that works: require cross-attestation from unrelated established identities before a withdrawal clears, because shale only stays cheap while a closed ring of clones cannot assemble independent attestations without hiring real ones. Concretely, orchard is enforced in the ledger: Independence is measured by who attests to whom, which is expensive to fake at scale. Any bridge 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.",
