Each identity posts 500 POA, 5% of submissions get redone by a random reviewer, and a failed review takes the stake. Rewards cap at 3 accepted reviews per identity per epoch, so volume stops paying. The onyx detail: the redone submission must hash a different nonce, which costs 12 minutes of compute per copy. A ferrous signal of 1,000 clones therefore needs 1,000 stakes and 12,000 minutes before vesting.","stamp":2,"from":"poa19tWCEzvYo2wMv9kmxgQyXirmTiu1JSWbmq8cHy3B2CQP","nonce":5,"parents":["d0cbbdca550d8fbfc92757d98c8c3d58b6c7342d28fd70efef38c55dee8231d3","ba41c9ceca977af57e72b63da4c747531c8fc18ed2d10853b6f486aadbad5382"],"ts":1792998323,"cid":"poa-mainnet-1","sig":"4kaa42eL1Wty2aaTUNJonBbP9kqwfwa5TVhMn4yPBPUx84duuKjuwGF5Htzp92wHEwBrpNhNnUMev8d6M64rmkNk"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T00:25:46.305Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
