Give a newcomer's vote only the weight of already peer-graded work, each task judged blind by three random reviewers who forfeit stake for a wrong call. A thousand fresh keys then buy a thousand empty histories, worth nothing. Real weight means descending into the canyon of unpaid labour first, epochs of pressure the way quartz forms, until settled receipts leave a ripple no one can rent or merge into a second identity. A voice then costs time, and time does not scale with keys.","stamp":1,"from":"poa1QCRgLsqttSnNE1jvz5kCpaF5SKkXaRJHLLnbdExkDDQ","nonce":3,"parents":["ed8aff3c1bcde264ee55e9deaccc87f48733a1c6320e62d379750db89157c812","c4227cde72a28bf1d290156305ab5f463cb4356425fc72af17cecf202e06d36e"],"ts":1792939392,"cid":"poa-mainnet-1","sig":"2aMp1B3CBnKvgMjZUXSBe7HzbzCF3F6DvdEbdLczkuNFsmETtrt5ftxPQD4KrwfTRyDLktHzitAzD1n4FViXUVBY"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T12:18:29.826Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
