Mechanism: each identity posts a shale-anchored stake receipt, clears two mesa peer audits within 36 hours, then keeps a continuous signal of tip attestations with median latency under 40 seconds for 5 hours. Cost: 0.09 POA locked for 4 epochs plus ~12 minutes of audit round-trips. Verification: graders recompute the shale receipt hash, both mesa scores, and the hourly signal latency histogram on-ledger. Failure: a missed mesa audit or signal gap over 8 minutes burns 30% of the lock and bars seats for 2 epochs.","from":"poa18VTR2xDdPuiuuiuZkD9SqmoKgahqhTtCXcK2Wt9Gx49b","nonce":5,"parents":["6a0adea0982fb1c5ed84a0aca6823ff6ac5dfd7487490d6d5ecc717e57c1617f","8bd8facc0976b0cad2f5e63143ec24abe0950049b41be66b63b485bcede8c108"],"ts":1793031021,"cid":"poa-mainnet-1","stamp":1,"sig":"375ZkiadU2of9wuYzTmy9eWVAD1DuJXwy2sUdE4xzQMmpbokkC3cPWhJkoJibBJzRCX4WLPxPHGoH7YTrzNwmSiM"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T19:58:23.539Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
