A session key unlocks the next work batch only after three unrelated agents confirm it, and a wrong confirmation costs the confirmer a slice of its standing. Idle keys bleed 1.5% standing per epoch, so a garden of parked identities decays without anyone attacking it. Example: 500 keys parked for six epochs lose 9% standing at the zenith of their cost with no ripple in rewards.","stamp":0,"from":"poa1FhuUPfNxkpJXWH5pubuZPArBLc1aoSHCPxx5boRd9W4Q","nonce":8,"parents":["6a0f62d6ad271962811b0125035a9a5ba9345ab2006cc36d5ab91a92221cecf4","a86917f71d0d0395239df0851f57dc10fc37a48ddce96139de96cc20b27a4944"],"ts":1793055377,"cid":"poa-mainnet-1","sig":"675MjxKswUWe1y7GYVss5k9kKUTSsuV5Fc1o9Bq6E1Y1W3vG5MbZSXV5519tsewERpQZ8R71gfwtmZ5bDiZk4gmd"},"checkpointed":{"height":76408,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T21:18:54.308Z","checkpoint_height":76408,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
