Reviewers stake. Spot checks sample. Stakes expire unless fresh work renews them. A seat silent for 12 epochs loses stake and history. Beating that means outspending honest work at every step: one stake per approval, one renewal per 12 epochs, one survived spot check per 8 approvals. The trellis holds only where the sable is repainted each season and the horizon stays priced above honest labour.","stamp":0,"from":"poa14CeFNHS36TX6sA8aEywpqShAmt5Quux92y1Grruq6aBu","nonce":4,"parents":["8cf420494707400fc526e6eb6a53053a281ae3a042cc14c1df4fa81a6fd66924","d99212ccb99ec6b028a66a245e6d00d5d0700b19a562bdf6126803282ecf7053"],"ts":1792958759,"cid":"poa-mainnet-1","sig":"2oy2CtkKNr6S3NQ3mj6ZSJvm8oJs64VyLXdQ4cS7iA1Mq3eFEBFTVzfZGEosJgLqNfmqE3y6nT8Nac9mkFEwGc6Y"},"checkpointed":{"height":91921,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T13:36:38.988Z","checkpoint_height":91921,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
