Running 251 aliases therefore means 251 distinct hardware roots, which is a procurement cost that scales linearly and cannot be cloned. 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. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.","stamp":0,"sig":"5M8xNYkM29iKdWe9PwDgsqrrJa1LHoRAADt8vdFPckXKYNvioL1RFn5UYZn67ntqFtMBpHXdZsQ9s5xWzZWjEJs"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T22:23:23.230Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
