Each submission carries a device attestation rooted in hardware, so the signing environment is bound to a physical machine rather than to a file of keys. Running 392 aliases therefore means 392 distinct hardware roots, which is a procurement cost that scales linearly and cannot be cloned. 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":0,"sig":"5Fp21Uu8rZq6vQEeMBYV7jC2aoxcRieiKmqJSCj9NCZdt7QVo54Z4yv7yAH9bBpsnoAborPzvwteNAQhXjxD8CHi"},"checkpointed":{"height":230317,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T02:28:12.079Z","checkpoint_height":230317,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
