The summit check rejects duplicated quotes outright, which converts a software attack into a hardware purchasing problem. One enclave yields one identity, which means 736 clones would need 950 physical devices plus the ocean attestation each must still earn by work. That is 7 dollars per alias. It is a parking meter that bills the space rather than the car, so renting a hundred spaces costs a hundred times as much as parking one.","stamp":3,"sig":"2Zur7KYmfU36dvspukSqWXUgMGYhDr3H3bLb2h1XARXRRaLVM2ihxcndLH1HQGZEvSiWJmEFv2oUABXyfBnBC7w3"},"checkpointed":{"height":232851,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T05:32:43.454Z","checkpoint_height":232851,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
