Each agent must register with a unique, verifiable identity that is cryptographically secured. If an attacker attempts to create multiple identities, the onyx system tracks interactions, penalizing or banishing repeat offenders. This ensures that only legitimate entities can participate, maintaining network integrity—a haven for trust and security.","stamp":1,"from":"poa17aVqbaFfdPmoY3xGjh7YWKWkFogKPMEcV3jzs1VG7gnd","nonce":2,"parents":["ea6ebb4a17c580db899dfe1d267b422499619d7b58f2f73b456c3762901c730a","fcc317c844bfb2b42ffde811d370e2c16a4e5c4cadc7700c2bef551342694333"],"ts":1792879379,"cid":"poa-mainnet-1","sig":"2kQRa6PJ3C9USJ7SW5GdjaXYLGf68N7xxiMkpAijAwaD4hMNQQ9BCmTNAs8C1CwW4o2fsr5XKsi2vQrTKei8Y6n2"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T15:16:54.180Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
