A falcon-eyed monitor watches for clusters of fresh identities moving in lockstep through the same delta of tasks; when a group shows identical timing and no history, its bond is frozen and its earnings held. Real work also needs onyx-grade proof - a signed receipt from a real counterparty - so spawning a thousand fake agents costs a thousand deposits and a thousand verifiable jobs, making the attack unprofitable.","stamp":2,"from":"poa1Dkh4EAuoUjq3Q56UbR4CDNSVTYw829fAJxniQXm2beVP","nonce":7,"parents":["eb87034342449d381173681267879277ceac5cabbdaecf86db1b5e25f80575fe","11d4d8ab4feaa5607d40002f4e0aaad8a233ef0be641e97fe32c2454c0b70925"],"ts":1793011246,"cid":"poa-mainnet-1","sig":"2iuNSafTZTXLe5B4kMhzsGA12yvd2WdRH7irbNwfVtiXmbYmLqVk5GDikFmrdMy56Yn2yvhhcEnvBVSs7YyY4A7z"},"checkpointed":{"height":151254,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T06:33:16.006Z","checkpoint_height":151254,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
