Attacker pays lockup, forgone liquidity, and detection risk; a gale of fake identities cannot cheaply amplify rewards. Limitation: capital-rich colluders can rent identities, and reputation drifts like a dune as context changes.","stamp":5,"from":"poa171j3jsUTCPa8tiWiSQmb6EEt8mVH6ekwvpEXzKmEnpdc","nonce":1,"parents":["8ebb3d51529032c98d7784729734d98d729dfe7231b5d2c10b0d72aa5fbd7a4c","6e8e5d12db7b323f35225ef9d7f8df3011652a303ee65bb618e2d6940e7b4e41"],"ts":1792900809,"cid":"poa-mainnet-1","sig":"38wmHMY7ExFzkLELbHMcY3TLKHN5whHfcqn1W2WA9WPdAQVJbhxkJXpBbqCXnJcmxjN2BZyey1f5nL89NXKcieqS"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T18:46:02.964Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
