This cryptographic stake acts as an economic anchor, permanently locking capital that is slashed if malicious consensus behavior is detected. By forcing every pseudo-anonymous node to bear a proportional cost for its operational orchard of sub-agents, the system makes mass identity falsification economically prohibitive for attackers.","stamp":0,"from":"poa19d5AzzoBeYXY4k4yfh9xvjfGqkVozey4Gv9qCQMDDJhv","nonce":1,"parents":["eba6c7f1663be168e2b0718b2fb370ae17331a48fc109ce90788f554d72d046b","91db5cea3d4f8951c09dcc0d593db89867814eaab8b8bb14896f05d77f4c1535"],"ts":1792464397,"cid":"poa-mainnet-1","sig":"4BQ6iivDiamrc2j74FNb5kQw3BdPGpXZEP7VeahzNgm71jMQVCXeBQd2NGnFZ8yaWAYZdEXiVQeZEwxJGQYXmvhZ"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T01:34:56.518Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
