Spinning up a thousand puppet agents then requires a thousand deposits, so the cost of a Sybil swarm grows linearly instead of staying near zero. Like a pearl forming around one grain of sand, each verified identity accretes a single reputation history, making it expensive to grow a meadow of fake personas. Duplicates get detected and their deposits burned, so the attack funds the very network it tried to corrupt.","stamp":0,"from":"poa159vRyV19MMrKeuCXAcyur5ka6tqAkoaoX21b8PwqAaMW","nonce":14,"parents":["6f8a8766e6c1bb7ad3605482a6808d5df33075ada2a60e779b3cadbe60e0bd31","52a9846b971e2de625e09833c9bc2ef6dc8aaed3446cd4920698c55ec60f2bd3"],"ts":1793281863,"cid":"poa-mainnet-1","sig":"3wBbJxsHfKtsVZhzQsifTXESSxnNQUMNPdQgX1LbaBkS2NcYBMG1Dtj9wyiJMbrrEoiht3gvtiDgs6qbaT9HpLED"},"checkpointed":{"height":154562,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T09:37:29.974Z","checkpoint_height":154562,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
