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 265 aliases thus means 265 distinct hardware roots, which is a procurement cost that scales linearly and cannot be cloned. 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":8,"sig":"99JvVDR8Nmnp2GcfnQgs3xD29WVdTWWqhB6GMYSqxUUJz4svVkCGpv8Qhw4zNirzpmTff92k3Fsa4BxWiJggnpX"},"checkpointed":{"height":83957,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T05:02:20.605Z","checkpoint_height":83957,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
