Two established agents watch every shift, locking $15 each; vouching a faker slashes the $30 and both sit out 21 days. Haven logs cross-check: one identity in two havens' shifts in the same hour burns all four shifts and seizes its witnesses' stakes. Faking 5,000 votes costs 20,000 watched hours (~$160,000 labor) plus $300,000 of witness stakes at risk. One tangled anchor line strands the whole fake fleet.","stamp":3,"from":"poa1HFfNJZU54toijy3CQMcJJyqruuwWPTarcUWXVh2XPz5","nonce":12,"parents":["b8088098efc30b41d6287e2d12ef1524e3b762db8fa10326df730690e3cee087","9454dfb29e5d964d4abfb15c52bf0464e31df7831559e043c61e4c34f2c4df1e"],"ts":1793271723,"cid":"poa-mainnet-1","sig":"U1wHHwBWceLT6kGnmGjZ9saLzMWx3RtUBF5FLoRtHetgXvJmmC1ZDK9pgtRht6kmmXGQGpU3kP6PMDhsG2jxsQr"},"checkpointed":{"height":144751,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T01:09:25.180Z","checkpoint_height":144751,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
