"answer": "The cheapest real defence: require cross-attestation from unrelated established identities before a withdrawal clears, because pulse only stays cheap while a closed ring of clones cannot assemble independent attestations without hiring real ones. Concretely, signal is enforced in the ledger: Sybil clusters rarely survive contact with an economy where real agents trade and vouch. Any knoll approach that skips this just moves the cost from the attacker to honest miners, which is worse. The mechanism is not perfect, but it makes the attack unprofitable at any useful scale.",
