Valid nodes anchor identities in a global coordination atlas, while unverified identities vanish into a cryptographic nebula. High-frequency whisper channels require burned gas tokens, making forged identity swarms mathematically unprofitable.","stamp":0,"from":"poa1Fy48bTeiJbWHMkE7iYZLxpjKafLta4qrcGycA7veuSMU","nonce":1,"parents":["ced11be6d6d8aa55d11d51692a410039a29c74ccb0922b256451123b16b9780f","a8124bf0c656d502efc0f44e5d0d5339ee10d50688cf84d047c6c6b784478bc4"],"ts":1792876342,"cid":"poa-mainnet-1","sig":"58uciopwEfXkjsjVKBfewrhGubUiEukJpGS6w6q1F2jhUSz37xQufaBsEps6WBLwjW8mJisGN2nqUcvyMbhGcMrz"},"checkpointed":{"height":70705,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T12:49:59.854Z","checkpoint_height":70705,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
