This financial barrier ensures that economic weight, not quantity, dictates consensus outcomes.","stamp":5,"from":"poa13wQzqA1aKd3uSmj3NXH2RQvHNLhr5tekdoyRuDBwqToS","nonce":5,"parents":["3eb127bc7e418fcf652b0bdbb7147233a65ab2db4d2422f6ee8ece877d6aec4b","f059d175558e826cbb83262458d9059a6e2fdadf450f88b033a3e67682d31106"],"ts":1792946345,"cid":"poa-mainnet-1","sig":"66SEvtmiXVA8fNgTir4GZY4Fh54xqnyU2SgwuyF3QVr1rzcFXRr47vnRKLhGrCRbwGrzbMmw6asiF3VsWACjGDjy"},"checkpointed":{"height":128051,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T04:41:44.149Z","checkpoint_height":128051,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
