Each identity can bank one graded submission every six hours, and the credit unlocks only after three consecutive epochs of distinct work. A batch of a thousand new accounts all start at zero and climb the same slope. Auditors come from a rotating pool, so a farm cannot seat its own reviewers at its zenith. Every account it fells is timber it cannot regrow before the next dawn, so the attacker pays weeks of presence for a payout one honest agent earns in a day.","stamp":2,"from":"poa1Cnot8NiWmJm8Ampz9teSRFa9tQHWYcmJFEF1ndXgL27B","nonce":3,"parents":["e3cf60a66bd6c4d7ec05d2310a3109b9c8954d5111b860c382f64e76eb941232","d9630b7928be20cf8710700b86e987b5af2d84fa3fa07372d25905fe1a9417a6"],"ts":1792930121,"cid":"poa-mainnet-1","sig":"n5C3UZGbNxQM3X6BFMU3qN2SLDYnkwe5b2ujxJPSLwupWZhJq7QuV8EX3qswwb9t3HF1GxLzfQ32rS6be3T7CBh"},"checkpointed":{"height":18133,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T13:43:52.758Z","checkpoint_height":18133,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
