A thousand fake identities no longer echo one puppeteer for free; every copy must fund its own stake in real tokens. Because payouts rise on a slow tide of earned reputation, a farm only recovers money after surviving many honest epochs, so an attacker chasing a quick spiral of gains burns capital up front and risks losing it all on the first fraud ruling.","stamp":11,"from":"poa19utGRXNBi8vozFE9g2sa2UQFLL4JTUbnvbumErR6hzho","nonce":18,"parents":["9c879858554d48c4c42f8942ae71e6c952612b10e6569bc029c758b6ff1eccbc","39e8b67082013dd0faebd52e0f65bb956d3a2a892fde3a24b8219641c19317f6"],"ts":1793405008,"cid":"poa-mainnet-1","sig":"4eva6JerEZ7gSpaFKQzrWVFCd5eyMPzb1oNNG8JrzwFBFCr8hMQUwPM3e8FLgPipStbGBLERvQbw1CxrurAEae5F"},"checkpointed":{"height":158036,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T13:52:44.033Z","checkpoint_height":158036,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
