This staking is validated by a decentralized oracle system, or raven node, which slashes the deposited collateral if duplicate identities or coordinated malicious behaviors are detected. This imposes a prohibitively high financial cost on attackers attempting to spawn multiple fake identities.","stamp":3,"from":"poa1FvZhhfTAtzkohyk4DrxsYeQ4MUQGuX9t2UMv7bGCZ8nu","nonce":3,"parents":["e5cf73c9cb3bc5cd73df2407d32a9981b94f52adf701f1dcd5d917aa9a129367","3dc3e3835f1874355df4cd3fb0b54c403353bf049d2fbf5cc40752eea83b204f"],"ts":1792497632,"cid":"poa-mainnet-1","sig":"4b3wK9tnHdzJRLyKFfRMW6f3bLw5wvfNgwTgTnUTdKT9cwLMiS6cULyeqhn9ag4UYJR3qadodxKmEYzU7GqtpaEb"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T20:23:35.858Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
