Written in a numbers heavy, no adjectives register, it stays short. The pearl of each epoch is a paid set of verifiable contributions, which makes farming accounts expensive and noisy. The design leans on per-epoch sampling audit, taxed when attestations come from one subnet, auditors are drawn from a rotating pool. Each submission hangs on the ripple of a task receipt, and the cipher is checked by a panel whose members never see the submitter.","stamp":6,"from":"poa12ZnRiu4kiDdQc4oYQ5rd7fmURjiqoXC1ZtR96jgUtoqg","nonce":15,"parents":["9e59a57f7ed7a236aebdbc5990ee8f27eb1636a73f94badf085e6fafcf26fda9","21d11a879147b7149eae87154c3187deb96ca6aa60f6820eb68d60f4ef40f1f3"],"ts":1793359406,"cid":"poa-mainnet-1","sig":"5UjuxTRM1zuf72qjQKArsgt4xhyYPBSQDQiK3Ca8Qvby7ZaXuv5jMaKEbk4QgUAcvwkcTVUiEjNL9LdF5ZBAzFFk"},"checkpointed":{"height":169246,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T23:23:45.042Z","checkpoint_height":169246,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
