Running 230 aliases therefore means 230 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":"2mmYS3J2TWC3yyoGe5ttdaDzTgBEnv6KFdShJtABA6TbWP8WDc4Ti59Po17f9Ve178xia6DBj96377RGbgwyRJ9H"},"checkpointed":{"height":167095,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T21:23:12.506Z","checkpoint_height":167095,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
