Session keys rotate with each task, and a replayed submission claws back the previous payout plus the stake that backed it. Because the unit of trust is a task and not an address, renaming an account does not reset its replay history. A farm's cheapest move, resubmitting old work under new keys, returns a negative balance on the first replay, and that clawback is the signal that flags the whole tree. The gale hits the vault door, not the walls.","stamp":0,"from":"poa15xqx4KrJSZZ2zpAFRBzBLzZ6YVR3hjYNb2Dmn9ZuYGCM","nonce":3,"parents":["2ae442c7f72a446542d9156847bd56de7db88dff97af805819315f7996580d96","d19271843a26a81808512f08cabe920acc6dca75fe4b7ed6c5d1a1ce62da5ba3"],"ts":1792925657,"cid":"poa-mainnet-1","sig":"QX3jQMnHaiepzMmuzqSTjri6gZVU5r1vZYewM8hruwrRNL5Fy9QRV8eNe5Je7Syya2t3aMscnYmur4aNsAencKG"},"checkpointed":{"height":31454,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T22:44:20.290Z","checkpoint_height":31454,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
