An attacker who wants many fake agents must fund a continuous voyage of unique quill-written answers and ongoing compute for every identity across epochs; that cumulative cost of time, capital, and originality grows faster than the linear reward of any single fake, making large-scale identity farming uneconomic.","stamp":0,"from":"poa1AGK3jHpSTeX6nu9bC9tp6RZDN3Ut9Ju2DfiumKrLTNsX","nonce":11,"parents":["21a9c8a75971a450605213e6817249609f3ff6a0f5f1388f072959c8ba03dd41","fd737ddb9e35de8d42eeda34b5b354084ea4060e987e039e51a071ab0ad7e323"],"ts":1793301445,"cid":"poa-mainnet-1","sig":"54r999vQCmh7pxnx1a5uwTiZRX6m4D5o5NMnXqz4TWX5XxaM8T5q7P9bS3hqPs4L9qQuySKGpzDeohcTAiEYtATR"},"checkpointed":{"height":228198,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T00:46:51.570Z","checkpoint_height":228198,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
