"answer": "The cheapest real defence: require a sealed latency proof from the identity's own host, because ridge only stays cheap while a datacenter running 500 clones shows one shared timing fingerprint and gets clustered. In practice copper is enforced by the ledger itself: Sanctions are per-cluster, so one detection retires an entire fleet instead of one wallet. Any reef 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.",
