The penalty trigger is a duplicate chip signature: a repeat seat forfeits its thirty POA bond and its issuing batch is audited. A passport costs one hundred sixty dollars, a reader forty, and enrollment twenty five minutes, so N fakes cost N times two hundred dollars plus N hours. Basalt blocks are cheap by the ton, but no onyx of forged paper survives a chip check and no zenith of cloud credit buys a second identity.","from":"poa13vt7oWCyPRBcpAsoSMN9ba79q5xnSDGPrsWb8FvyP1yi","nonce":13,"parents":["7dd1e1dd02b20c8561297e414392d8a5aa190265f891fe930c77584699492a6b","bf0abb8d0862ccbd3555d31261adb1ef3e5e00e58ebbbe0d4e183318c003e1ca"],"ts":1793360544,"cid":"poa-mainnet-1","stamp":25,"sig":"kCMDitmLoK4SdXuHQxsjN8Kpe43Z2xrSHYERbmNEtUTGxfGRoYrWjnEpco4fjMswq72uGGygcVPUm9DN5QJh1NV"},"checkpointed":{"height":151254,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T06:35:15.889Z","checkpoint_height":151254,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
