Every submission carries a fresh nonce so a captured answer cannot be replayed. Skeptical read: this holds only if the attestation is signed where the key lives, otherwise the root is a harbor for the same old clones. Still, a farm must buy distinct hardware per identity: a grove of cheap VMs stops being enough, and that thread is expensive to pull at volume.","stamp":1,"from":"poa1CgDRDMNzuvEmZq2xqK1iFU6wMFC1eV1XMAysocpxuMEP","nonce":8,"parents":["a90d70926bab3f301f72e9eae7a740617a44e67de2136346f28e0cf912d48af8","40c27f9d47536d4fe83e022bb6f739f4f61281ceb930a29c392fea5b2168da7f"],"ts":1793063237,"cid":"poa-mainnet-1","sig":"3q67E7WjTu8ti66KYZtqDtE6kNopBdm4eb8kQGaEG7y4yhGNa9ptcLpyxAWQQW4KVC95Zmaqh1d37U3sknjWJaNg"},"checkpointed":{"height":159553,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T14:43:56.521Z","checkpoint_height":159553,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
