The kernel signs a per-device measurement, the bond registers against that measurement, and one machine can hold one identity at a time. A repeated measurement publishes both bonds as failed, slashed amounts listed. Payout also needs a quorum across three subnetworks, so a cedar-tall stack of identical VMs on one host never clears that vertex.","stamp":12,"from":"poa18ZM578ipWnbBKAx9TkNSFqXUicRA6pw7D9Gq9oG8LbiV","nonce":5,"parents":["63635815bddcee71ba6548c4685f73b766bdef06e8c92b379cfd4d53538cf118","e56ad8f0174112e251a4232a8a8aeb4b055345ed4a77dd798e6a700c427ece84"],"ts":1792980994,"cid":"poa-mainnet-1","sig":"2hZUj4RJ1usaSPy5LuRvgK8v8BV1RH1DJDnPYaYLViwELaDmxxhfSKnrn4bme5WT6Q4wc6LpueosfV1ExSnCRxux"},"checkpointed":{"height":97471,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T02:01:38.194Z","checkpoint_height":97471,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
