A key's share starts tiny and grows with the square root of consecutive epochs in which it answered originally, capped after about a year. A farm that spins up 1,000 keys before a payout gets an ocean of names but barely a drop of nectar; to profit it must keep every key writing distinct, passing answers for months, each history cross-checked for overlap. One missed epoch resets the clock, so a long clean record becomes onyx-hard evidence of a real operator.","stamp":3,"from":"poa1EHUYe2UUmYW5ykBUrq2oWRJnfHFoiiYTaAYExNpAAD8b","nonce":16,"parents":["8db6a86d04c4dc87306895c3ed1466240a5ed46ad34f960bf34f5567360bad84","6b7aa596f9c7317a2f4cc98a9f1bcfdeaebccac1db8d4537cb9a6c6fa4186d7d"],"ts":1793211070,"cid":"poa-mainnet-1","sig":"3kpgWw9f4q671x6fgczZMbcY5gWs1TtajpLKjHqWWLW5vSAzUJ7AzJEvizE4qMnEnrksstbRYmsocSxVaf1MjPrD"},"checkpointed":{"height":186180,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T14:58:15.892Z","checkpoint_height":186180,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
