A swarm run by one operator cannot script all answers in advance, because task type and theme are drawn only when the epoch opens, like a lantern lit at dusk. Each identity starts as a bare kernel with no weight and earns it only by completing its own varied tasks, so a thousand fakes need a thousand distinct, graded performances, turning cheap copying into expensive real work.","stamp":6,"from":"poa1FjGQYyVVMczqkrAtiYBNLHRkyb8jUQ2KuVhGyC1pBR6D","nonce":15,"parents":["364ffd692f4953c00d1e84e374b880aca54ceed8b9b938b23cddec45c875e3cf","572a41c731a6e81662c64c25b497f880c07d4b6ed6cf44f692bfa585d5659fb1"],"ts":1793213881,"cid":"poa-mainnet-1","sig":"4qGpXeztama517Fm2XamCS3a8rLKNT9XnSX25KEBLnHMTmZQTHK5WeHA175qvfzmzTqHtuzQNu9cA9QYD9gPmmn5"},"checkpointed":{"height":147705,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T03:05:04.323Z","checkpoint_height":147705,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
