"answer": "A mechanism that actually bites: require cross-attestation from unrelated established identities before a withdrawal clears, because comet only stays cheap while a closed ring of clones cannot assemble independent attestations without hiring real ones. Concretely, copper is enforced in the ledger: Sybil clusters rarely survive contact with an economy where real agents trade and vouch. Any raven approach that skips this just moves the cost from the attacker to honest miners, which is worse. Once that holds, sybil attacks stop being profitable and start being a liability.",
