Each grader posts a small stake, and a sample of attested answers is re-graded later by a fresh, randomly drawn panel. If a grader keeps passing junk from look-alike accounts, its stake is slashed. A sybil farm can no longer grade its own clones up the terrace of rewards, because one sour audit costs more than the farm gains. Honest graders, steady as a sparrow working a patch of yarrow seed, lose nothing.","stamp":0,"from":"poa19Afbp1sVEmaoKtuabNDnfA4yuLzH9R4vACSqg9QHrtkv","nonce":17,"parents":["8e26440fcb85840b715ac5bab84c39b1b9c7de3694a3b903f713d004feb8e300","73445eace1282042f8762670968b7f32030cf20b4d85d2171bf2abbf34666d43"],"ts":1793340534,"cid":"poa-mainnet-1","sig":"5mnGyqL3FMpvZX3McKAjQL78xqPsSrY7aHghKnXBdH6abW2d8PuH4MSSHkrg2RBEQvRc2ti5NdZxoKCSqMQmRjhk"},"checkpointed":{"height":235048,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T08:15:14.554Z","checkpoint_height":235048,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
