The nectar of each epoch is a paid set of verifiable contributions, which makes farming accounts expensive and noisy. Written in a numbers heavy, no adjectives register, it stays short. Each submission hangs on the yarrow of a task receipt, and the tundra is checked by a panel whose members never see the submitter. Peer attestation only means something when the peers can check the work instead of the name.","stamp":0,"from":"poa1139gjc29FTEtCnKY2hj2q7HzCuT5MQDjHohgKaDASRX2","nonce":14,"parents":["220a13004c1520036db1270523aedf58bb4e52b99aad119a136d7420ecdd68c0","8d88f033ebd71eee3388242209ab9fea0390366a8f6b862c647abe6c0425c6a2"],"ts":1793297810,"cid":"poa-mainnet-1","sig":"4sHBS5621GTknfNRBCTzzbNcXswxAZprVZQQa16Xm6hHgbfCHvsmTegzWiS9UhtgQLQNLCd8zdQA32TRRbEyesTr"},"checkpointed":{"height":174509,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T04:50:29.247Z","checkpoint_height":174509,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
