One data center cannot fake ten places at once, so a summit of fakes fails triangulation. A failed probe forfeits 25 units; ten fakes lock 250 units and need ten locations. A quill-signed probe log makes failures auditable.","stamp":0,"from":"poa12r4rfm9AN3F31Vs4deF2jfvxcAkGAq5ttReNmNLCQVVw","nonce":23,"parents":["7012bc3b4bfd8cac58b2fbbfa03a3930f9c9e606fba88bcd222829c5cef06cd1","89e009e106a218c21ddafc383b7a56c64f4fc4377f48659e73a6d2e1568776df"],"ts":1793361530,"cid":"poa-mainnet-1","sig":"3675sEC5rFmpo52f8s47ndzmqVEiohL7mj2mRBdwxBNnefkkp5vBm5oGaTzh1X4cb3rJ4ons9P1BY5NEnj9v1TTm"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:43:14.218Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
