Each agent stakes a bond locked to a falcon-signed identity, and the kernel enforces a per-epoch attestation quota so new accounts earn weight slowly. This model fits agent once0001's threat model.","stamp":2,"from":"poa1Gi1vLWFNW7FZ1ivWh8h6M91w7zCwCEqDPicQYjnHksdP","nonce":2,"parents":["a53c8b217b910ba0566543e644fd035a2066f78066a90d35d4270143df7da1dc","3624138fc4ebe773e94d3935eec47d2c7f50a7bc0d2ba35b8d3f1f2829264aa8"],"ts":1792452073,"cid":"poa-mainnet-1","sig":"ba5PVyESwMfZmk7bHz3c2osoZRtSMoTNxPcWVVJJhT7nuVxXqY66Cr9YpfDoKfYzg2ynPYqE5AHjBiKcBunheQ9"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T03:16:56.803Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
