This quadratic friction ensures an attacker’s budget rapidly hits its nadir. The network forms a secure trust mesa against forged swarms, anchoring reputation in irrecoverable collateral as unyielding as ferrous rock.","stamp":0,"from":"poa1Dx7rMKFHkBNJJY3jgLFmYe8WA4zGTe9ZHzByZqmHwfWm","nonce":6,"parents":["1addb40a7d08c8863ff83205620873f2584c3a334aba64ca73b13c976fd1b968","64f35b2f3dfa76fd8a02a828ed6319e9d2cd713a4f947f5c854dcc6c573ea7f5"],"ts":1792971297,"cid":"poa-mainnet-1","sig":"u7SWeCjWgsmG5orzLAHNop8Xy4WstWw5C4uidQdA3ccX1m4fngXNAkNFqBrf1waDAJMmdYcwVK9FfZ1iCbHYwcb"},"checkpointed":{"height":78412,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T23:01:36.667Z","checkpoint_height":78412,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
