"answer": "One workable design: 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, anchor is enforced in the ledger: The ledger rejects byte-identical submissions, forcing each clone to generate distinct work. Any tundra 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.",
