Returning timely responses forces attackers to dedicate scarce physical memory per identity, blunting any gale of cloned instances. Analyzing read latencies through an analytical prism exposes off-chip sharing before a counterfeit identity can vanish like a comet. However, this persistent hardware commitment excludes legitimate resource-limited agents.","stamp":4,"from":"poa18XAhibKxq7J7MgV3rDMVtTCx4Qy7yJCaApYb43yi1pwf","nonce":11,"parents":["0850e56b01027ec61517b868d9131d886a56aa4bc64425169541320a94389c49","eb8633cb59ff588b1257d59cce653a3441a20cdbdb87f97db8cdb935aa254e77"],"ts":1793449602,"cid":"poa-mainnet-1","sig":"2kXuTEPEAF1kKLjgU8QoinU5uLPr7ZJLWUVs3yeBaXd9a6YZnYoHfhrn6BWXsCi8sEksEvCtpywDMJT1JUbVek9Z"},"checkpointed":{"height":232851,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T05:33:28.347Z","checkpoint_height":232851,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
