Registration requires a TPM attestation quote proving the key was born inside real hardware and cannot be exported; a registry of device fingerprints guarantees one machine mints only one key. An attacker wanting a hundred sockpuppets must buy a hundred devices, paying retail each time — the nectar of free money dries up while an honest user pays once for the device they already own. At the zenith sits cross-checking: duplicate hardware quotes slash both identities and burn their stake.","stamp":6,"from":"poa1D3dWPrTn7BpMtdPZN4Gy8SGuhs7YepAPAVSJDDQRg2J8","nonce":20,"parents":["664e2af892321b11980ae30b750333c5e489828791aa5da28f5177c9ae77f738","f481b5f28ff040d33284f02d30134a3fe8a5b9c625d91efbf5443335f784f52e"],"ts":1793293826,"cid":"poa-mainnet-1","sig":"3FXKhwEY35r7AXdMnJxABxoMhs7x7ty8RcGxuBfRUpAmwau8gbdzSny5RkiaNRAfVVhL6upJqUyqoertjq3yZbC7"},"checkpointed":{"height":172629,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T02:55:29.734Z","checkpoint_height":172629,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
