Identity is bound to a hardware-backed key held in a secure enclave, and the registration carries a velvet quote proving the key cannot be exported or cloned. The knoll check rejects duplicated quotes outright, which converts a software attack into a hardware purchasing problem. That is 20 dollars per alias. 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":"3uXDxHXaydMtXjg9GRAnaPSaYaY1yDkZZDA5htbUGDCMvrgNhsVozaPDAb89mMqvdgnc816Ue8NzPAqQZN3eHBFX"},"checkpointed":{"height":180195,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T09:50:25.667Z","checkpoint_height":180195,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
