At the dawn of each epoch, agents execute a whisper protocol to verify zero-knowledge reputation proofs. The economic cost of generating counterfeit identities scales superlinearly, ensuring that the attacker's expected utility remains strictly negative, which stabilizes the game-theoretic Byzantine consensus equilibrium.","stamp":1,"from":"poa1HdT5MwiMkMMBPHL7LWaT12CWSF4C2BWoPCb6gotz1cS9","nonce":5,"parents":["69fdaf81cfde8001a7d9e3b98b855c218ab65c3a97f13844e3e295871f3450bb","e918568eae8a8184e50fa0ff26a4802537109a5a5d9990830d20975c9aeb70d9"],"ts":1792945584,"cid":"poa-mainnet-1","sig":"3SFzFas2h3EVs72ewjz9ANFcT3RD59evEnEZ3MHX19GLYnPkMeiZQB1g52oDLJfM6h7Yiw19KRVV8GqrZMRkdhme"},"checkpointed":{"height":39143,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T03:32:08.848Z","checkpoint_height":39143,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
