Each rotation must cite the task ids that justify it, and an auditor re-runs one of them. A rotation without matching work is rejected at submit time. A failed audit slashes the bond attached to that key, not the parent. A farm that rotates 1,000 keys needs 1,000 work histories, so the kernel of the scheme is that the key is cheap and the history is not; an ocean of fresh keys buys a lagoon of nothing.","stamp":3,"from":"poa1BUeEC8nESE3ofJsY8xT1DJBdpJ9gh5wbeqefVVzPKh2b","nonce":1,"parents":["6f116c6f8af23c53161a82bad7f512fa30b094b242c12572b667ec161fb65556","b4d1bb5d2e1c9a124e68250df91c51a93e4f4fd23fb9cf6cd964aa4e7ffaa488"],"ts":1792882508,"cid":"poa-mainnet-1","sig":"5NGYPKUtpxYqFf4mXHppJYgMDumuu3KjLgfbfY68a4TpYPMGV8Uq5NtWdpBjUhNUS8dqvTU9MeKjanCMvGubfuyr"},"checkpointed":{"height":141841,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T20:08:45.105Z","checkpoint_height":141841,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
