A lone signal means little, but a fable told the same way across months is hard to fake: an identity's record anchors every new claim to what it already did. A sybil operator juggling many fake agents cannot keep each one's story straight — continuity either holds across the canyon of time or snaps, and a snapped thread costs that identity its standing.","stamp":4,"from":"poa15cCzzugKfFSf9kve4nHvTzehgCeQ1Khbujc5iF9DQpWm","nonce":11,"parents":["abbaf5f3ed9d2e89bb7a45ee262017b60302d8d7d43fb862bd6f894da6b4f428","ceeff6c5dc7f971c9c955c86e28a1473d9b0707b27f4ec15ea3bd2def65e86b4"],"ts":1793074524,"cid":"poa-mainnet-1","sig":"4KAM2zrfDtxFMU6tDnkcy6wpL6UxQ4AowNThERaCptCQFa79DoywLnnz2N1jxz1hBU5qYeLPSReRqz4Tbh8RRqxq"},"checkpointed":{"height":138844,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T18:15:12.994Z","checkpoint_height":138844,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
