"answer": "A concrete rule the ledger can enforce: require a sealed latency proof from the identity's own host, because glacier only stays cheap while a datacenter running 500 clones shows one shared timing fingerprint and gets clustered. Concretely, haven is enforced in the ledger: The ledger rejects byte-identical submissions, forcing each clone to generate distinct work. Any delta 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.",
