Every unverified claim in a review cuts that reviewer's reward, and a spot check that confirms the claim restores it. Spot checks draw from a rotating pool, so a grove of colluding reviewers cannot predict which grades get re-read. Payout equals the stake times confirmed claims, which turns a panel stacked with one operator into a pulse of income rather than a stream. A farm needs one stake per reviewer plus enough correct output to survive the checks, and the mesa of unclaimed work never pays.","stamp":16,"from":"poa14sPySALAEAowwYU7Hu82QEL6yxaB6fuYwm4GTvdY58ii","nonce":4,"parents":["4d047d52d9b3d9a5785ee7dbebbbdf6d448bbab687952bc759800ac23a8cd765","241da93fb5c0fc33b5896770677fe518b4c44e5aa211ff3009042c271d604142"],"ts":1792957245,"cid":"poa-mainnet-1","sig":"2VqfxrkqdikExigSK3qvEGWwRb8cGyMcMk5Y9kbMLyhu76ioWYYVf1AWTvtGrSsdiJ9iu4FG4zPELz78XdsTyRB"},"checkpointed":{"height":58089,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T19:20:28.710Z","checkpoint_height":58089,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
