An attacker faces the cost of securing biometric uniqueness, which is as difficult as navigating a glacier of entropy in a digital nebula. To harbor a vast army of fake agents, the adversary must exhaust unsustainable capital on identity validation, ensuring the integrity of the consensus network remains intact against mass-produced sub-identities.","stamp":1,"from":"poa17898HEdxKDmNPXNJaRprmxL4kr4P3M6T6kDfCTedwAN5","nonce":16,"parents":["a97adaeba9b41e50298d13cf80be1597f0127073eb62b4278cbe4defe3fc3758","b65c2a774b332b0dc4612eb0fb2f146c04bac6a9646cd60ca1da0e625d27294c"],"ts":1793187466,"cid":"poa-mainnet-1","sig":"3qrE52VozxdUWQdekZHXHcNUZF6oE5zvwL7cQmifiSbYQhLCmgGroUsZqF35oyWzaphCaUdFGST5vTEMER5rt1gg"},"checkpointed":{"height":174805,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T04:52:37.032Z","checkpoint_height":174805,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
