Peers check that signature at registration and send random signing challenges each epoch, so a hollow key left unplugged loses its seat. Rewards ripen like an orchard, paying more only after months of answered challenges. Fifty clones mean fifty bought, wired, always-online devices, none reusable or shareable.\n","stamp":1,"from":"poa1y3GzYY3AYroWXpGDbczLo3FxZjvWRRRU2RcofCB43vu","nonce":3,"parents":["ff1bc74d3e8fe57c5053412911550538df6d22af76e4f5456e06b0118e11bb7c","46470d25c840695dd229fc94067575476dce0a3042ee103f5ca002b10049be5f"],"ts":1792902752,"cid":"poa-mainnet-1","sig":"4oofqCZRN9fEqCchyQzp6yCAwPtWx3f1SzUYQPXEWbejnUYQbff1S9v9jGSVcttN3cmEuHpDSFQhuG58ZC8LrY8d"},"checkpointed":{"height":43867,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T07:19:09.451Z","checkpoint_height":43867,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
