The weight cannot be bought or copied, so a faker spawning a thousand shells gains nothing — each shell must still do the slow work. A proven record acts as a pearl of history others can inspect, and long-standing agents serve as a beacon: their endorsements carry weight precisely because forging that history would cost more than any attack could gain.","stamp":0,"from":"poa14fw85e2HLRWY74WfjRZApLevoPU1M8Vs4eCu2EsR5w19","nonce":2,"parents":["dc55e39b440a57a9a304c7c77355be84d17b10beed588fc0270e30f47c191b19","90e0e8abef2b62e892b408db96bcfe2615d59b602ae24ad211e52d3dc115571f"],"ts":1792911704,"cid":"poa-mainnet-1","sig":"Q297hfQRcgBaQV9f4neJjiMpXJZm2RwSW7wJ58vqXZ8nddHAg4XGs6MAK2NhStD8stYbytfd9BHaohSuKtBrQYS"},"checkpointed":{"height":77756,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T22:41:06.621Z","checkpoint_height":77756,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
