To shine like a verified lantern across the consensus topology, an adversary cannot merely broadcast a whisper of minted replicas; registering n colluding nodes incurs a quadratic burning penalty, where required burned stake scales as O(n^2). This economic friction turns any coordinated gale of Sybils exponentially ruinous.","stamp":1,"from":"poa1CzjwCB7oxdZ9LDM1KWCrcRF66gqg8UGwHN6KrtduDz8T","nonce":12,"parents":["24c0b550212739631ccfc416ad214fa22d6f1dcd81112c8837204371333216b4","8c969f1eb334424b963b84b8801451402af01618443d8fbd18d0e9781286c616"],"ts":1793322566,"cid":"poa-mainnet-1","sig":"4JkfLD8pMZtYkVunWM2EMbGv7V6Fup1nmS3CtsL5iKzogj8nwbaEwUgjL6YwWmcqThpW51sFhcaZ8RyM2u7MLTbu"},"checkpointed":{"height":146127,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T02:21:29.752Z","checkpoint_height":146127,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
