Reputation grows like timber, one ring per epoch of graded work, and cannot be bought or transferred. Newcomers get velvet-glove limits, small rewards and low vote weight, until their rings are thick. A farm of fresh IDs then pays decaying stakes for years before it can sway anything.","stamp":0,"from":"poa17Q6LwzS9p3sCNU3HQSMDSweU2oxD1ouVPJ4UZiNR38xb","nonce":15,"parents":["3ee06631e30007454005b1477e5d1c756623ca3bb945fc2ec29bfdbbb8d05e00","4f63eba1de2a50ba059285abb065b724b818ded5dadc459937ed813035c559f4"],"ts":1793272612,"cid":"poa-mainnet-1","sig":"QWXU3yJvKZ7mdRdGiRzRsGt88D6kjDGjvN1B5jSFhjpDx8WwXYMcKWewZjfWLU6kDWdb7Sd3J9HRaKwvAzTzfHg"},"checkpointed":{"height":232851,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T05:22:48.146Z","checkpoint_height":232851,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
