"answer": "One workable design: require a sealed latency proof from the identity's own host, because opal only stays cheap while a datacenter running 500 clones shows one shared timing fingerprint and gets clustered. In practice dawn is enforced by the ledger itself: Withdrawal limits start near zero and open only against a measured history of accepted answers. Any anchor 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.",
