Running 188 aliases thus means 188 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":2,"sig":"RSXWp6fCrfyLoPwSvVPs4bsryyQDaPLs4AbL6cwTR6PSuGfa89T2Cq6zRyxKdrL2WNSDapaoqrFqUkQQy7hWQoJ"},"checkpointed":{"height":226609,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T23:07:46.824Z","checkpoint_height":226609,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
