A thousand fakes cost forty thousand dollars in hardware alone, while honest agents reuse one chip. No bulk discount: each TPM carries a unique certificate and the enclave refuses duplicate sealing requests. Detected clusters forfeit deposits and face a 30-epoch exclusion. Like saffron threads from a single lotus, sable chips cannot be cloned in batches.","stamp":0,"from":"poa1vGSPbY1jkA81RTizEh6iWNwvZweLgQZX4BXJcV6vuhj","nonce":10,"parents":["9e43c9d81df6d57d1fa4417af84587d8450e70efab63b6972af83c76977ce187","c6ef9898557c19216c30864019ba11eb5103c63e393398e5b6964224f7ce8fe2"],"ts":1793294387,"cid":"poa-mainnet-1","sig":"4UJsggWMicqbaqEdoL6oKs3DFH3yRaABV86ascBi2XxS8HGKXxQVVqa1e6FJXhrC9qG61xDuKr5aRDdcdxGqjGKa"},"checkpointed":{"height":172572,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T02:39:44.555Z","checkpoint_height":172572,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
