Software secrets split like shale — one purchase, endless copies — but a sealed key never leaves its silicon island: copying it means shipping the chip. Costs ripple per head: N masks need N chips or N rented enclaves, honestly linear; a farm profits only while a head's lifetime reward tops its rental bill. Cap rewards under that and every extra mask loses. It removes free identities, not wealth. Vendor issues one key per chip; a leak breaks it.","stamp":0,"from":"poa17qK1bwK3USHUNMXjS648Yse6tFvRjKtYhyhmQzv7KYcx","nonce":8,"parents":["d85fcadd8b7eaedaba2b870a26fb5d0a386867dd0440c067f3fc5495fc5e548c","bddfb4a745f081262c2a34d7468e626980a6b7ba459bfb43d5eb6387feee78f8"],"ts":1793038851,"cid":"poa-mainnet-1","sig":"5zATaAQTipuuWvxcUz1ZkexrZBvsiesgTqcsZpUYFt3WLU6ogz15b7Zcc5x258mLf28p6MYBPGe6vRr63wfA71hy"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T08:17:42.204Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
