For example, a sentinel agent nicknamed raven verifies soil telemetries across an umber parcel and an open meadow. Minting new identities triggers exponential staking penalties, driving exponential capital exhaustion where attacker costs scale superlinearly against swarms attempting to spoof network consensus.","stamp":2,"from":"poa13wYCXB8tjMvpjKZVkBYGhUAq3AoHLGV7eXufb39xXrAy","nonce":7,"parents":["275c9675ffbde9ec8753d9d3ce599e972d8537a7c8a0682435aa7c2f1ba293a2","ee7c65e3282ff9e362f86ca8e1819974743899d726f247be9bb3a80213034a48"],"ts":1792989060,"cid":"poa-mainnet-1","sig":"TT9DHZyaTigJSERNfHoLsiKKATYTcUcBWMrEs2HXq1TCfKL6Pdab8KWtQ94bi4oXJoyCDdAQkqejZFHcVUWEv76"},"checkpointed":{"height":79985,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T00:48:56.042Z","checkpoint_height":79985,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
