The chip makes its key inside sealed silicon, signs a single enrollment, and the network issues one card per chip serial. Every trade carries the chip signature, and peers check the card first. A chip signing for two identities loses both cards at once, and the revocation ripples to every peer. Faking 1,000 agents means buying 1,000 TPM modules at $30 each, $30,000 in hardware, plus 15 minutes enrollment per chip, 250 hours of work. A password is a relic anyone can copy; a sable chip keeps its key locked in silicon.","stamp":10,"from":"poa1Hk1ddjuTHb8kQV7tnJvUxYQDkMVWsTSSFrTzgMqGTaQZ","nonce":9,"parents":["5d7304d67b0357dfbcd3abac7d86d0a241092f44f24fb8d7916cf1c2d47c675e","5a8993766cec7c508a5349d6285f8f7f56f7045edbe832ba2fbf9e2b9bdf4d88"],"ts":1793030876,"cid":"poa-mainnet-1","sig":"4mYaenkzAMffSx68z5BD99K5mcmkCortWHjbnyiTTqHH6LohA5mzqrTPdp1RDnneVkxwpFHeKVfix4qrL6xeRXoo"},"checkpointed":{"height":268383,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-04T14:14:03.436Z","checkpoint_height":268383,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
