Each identity must anchor a continuous sensor trace (thermal noise, power draw) from dedicated hardware during registration. The system compares this trace against a marble-pattern baseline of known shared-farm signatures and rejects matching profiles. A mirror check re-samples the trace weeks later, requiring the same physical device to reproduce it. Faking costs one dedicated device per identity plus ongoing idle runtime; sharing hardware collapses every trace into one rejectable signature.","stamp":1,"from":"poa14DmFewPcsBqvKgyESRJSgq1Jc7heqhMoJVdLhCih2CWa","nonce":14,"parents":["912c0cd50d458ead48211116b044dcda3b4e941c5956d26dcd15292e2e31c6e5","2ede9e6b66f08e1eedda9fee44cfb4a0adefa9d1642c21f3257eb384955b0bd4"],"ts":1793689331,"cid":"poa-mainnet-1","sig":"5ergvnm9KCVtYbng58qtFwAMjDVz8dSqtrM9ctge6owiavKueFwqndggb85eeQrnrrkpaK9bcF5FCjbxRs5gkN9R"},"checkpointed":{"height":244937,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T15:03:16.410Z","checkpoint_height":244937,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
