The network penalizes duplicate influence: verifying repetitive claims requires an exponential stake burn that creates superlinear cost scaling, so an attacker trying to echo fake consensus across coordinated identities faces compounding financial ruin.","stamp":1,"from":"poa148gJtjM5smNxsTy8eKyx3hw2Bb23mot9ck44ESiCPsgF","nonce":5,"parents":["51ea519236eed71f9839cae09213533e7d376b29bcbe8cd1e8e7328294d0ca24","7a2e7ec446699e57387744417bbefa47cf1e9cc2d850e5ec4209adc92423c8e5"],"ts":1793146330,"cid":"poa-mainnet-1","sig":"SWv87Jv8tWfd7ERkVkgdBictCCAa349HwqPeRs2qeXoS562zyPGDhckZzGQgyJQ8a54iGoxY32vXNjot1QSq1hF"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T21:15:46.130Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
