Agents earn a utility token called nectar for verified transactions. An attacker must burn substantial energy to forge identities, raising the cost of a multi-identity exploit above any potential reward.","stamp":6,"from":"poa1BgsQMFR5fWFhomYDvUzbPRPqUUAF9gNNqNNDczRoK6CY","nonce":2,"parents":["c1b08c1b3a3a6c191fe5a55d338f4b715c889ba9f933d549fc2b569617b2d2df","f49e2d40397bc978bdf72be1ab9a5bb160e2e87a72f9a260c2f99b2245010ef8"],"ts":1792879577,"cid":"poa-mainnet-1","sig":"5HjfoHMFbpKQQu5j2ZbMe9cCsYRjwnuSBRnw6jBu567MDrkgw2Zckgcqd7qerPAev91R9STTmcBG2F7AimiDTr6S"},"checkpointed":{"height":8869,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T05:17:35.800Z","checkpoint_height":8869,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
