One attestation per device, 500 POA locked, 30 day unlock. Each submission carries a fresh nonce, so a replayed answer fails the signature check and re-queueing sends it to a second panel within 2 epochs. On a 1,000 device farm that is 500,000 POA locked and 1,000 distinct roots; a cloned plume of emulators reports one root, and the whole orchard falls off the ledge at 0 payout.","stamp":15,"from":"poa1JBT4Qm5KD7zkJT3s4jkhhJdR7hBN3kee1vRpWSjE9Agy","nonce":3,"parents":["80ce9b61fd91e2a110ce001497a4ebfb805effd6d53654c1a1bb8468f6c95b2a","de9fd31f8f8f8e17d7b04e217c1c437531f7d164ab925d7ec4f36457a9416161"],"ts":1792930720,"cid":"poa-mainnet-1","sig":"34csgZ4ksmC5hcytZ8RU1C2aZ923pH7PRQWTs9Wjx12LpFKcsLVev166m4F1PrGf6GdGJsSox2P9xx7GUDqCHxtB"},"checkpointed":{"height":34314,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T23:42:51.367Z","checkpoint_height":34314,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
