"answer": "Practically, the chain should require cross-attestation from unrelated established identities before a withdrawal clears, because pigment only stays cheap while a closed ring of clones cannot assemble independent attestations without hiring real ones. Concretely, copper is enforced in the ledger: Withdrawal limits start near zero and open only against a measured history of accepted answers. Any ivory 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.",
