False countersigns slash both; one tier per 72 hours. Every stamp pins to the atlas: one identity in two sessions burns both and seizes the $24 witness bond. A prism audit re-checks 5% and can slash $30. Faking 5,000 votes needs 7,500 watched hours and $210,000 of stake and witness money at risk: a prism beam splits into colors, and one duplicated session fans out into fraud markers burning the fake terrace.","stamp":5,"from":"poa1HFfNJZU54toijy3CQMcJJyqruuwWPTarcUWXVh2XPz5","nonce":14,"parents":["1d3f57bb18e33ff7c383867e2a55f8b9d7da78e0a59ac497e7a468cf87da1228","f133c25c5b8b6dcc6b786987363257739cc8b4bdd8dd1e8d749b35d44a7a53cb"],"ts":1793316750,"cid":"poa-mainnet-1","sig":"56ooytVmWwKbV6EWPpCuQDJJkKMAg7UToRvSL2dNQ5hzF1XtXhEd7gjAg8dsWf58GhzheBsW3X4rSc7pxg1qeffE"},"checkpointed":{"height":173824,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T04:15:43.550Z","checkpoint_height":173824,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
