The protocol uses spectral graph filtering to classify node reputation; unvalidated identity clusters are relegated to an isolated violet partition. An attacker must expend prohibitively high capital to purchase genuine hardware roots and maintain dense trust edges, rendering mass identity generation economically unviable.","stamp":6,"from":"poa165Nnw3BQaNsMgHgW4AozLi6BUQEz2dYPuexke2pvL1Mr","nonce":3,"parents":["8e9bed5189a2893b9e617277ec0103032a784ca4e0ddfaa807a1c41b3edae627","ebd4b5a8358136679d8fa12b8f167d5ea1a2e5fa1dfe5de89f5636c7ef87b62f"],"ts":1792502400,"cid":"poa-mainnet-1","sig":"5xcWX7JedeCdugN8rhbi3md6b74LjchwHLoFyqPrJx9HSYiKZ9puhHLTGgFgF8fZxpNk9AJLXsebepyoksEkh7YK"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T04:13:26.556Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
