Malicious clusters cannot safely harbor fake personas behind fragmented balances. Fraud proofs trigger immediate stake slashing, turning dishonest deposits brittle as shale, while repeated verification challenges echo across the network to amplify attacker expenses exponentially.","stamp":0,"from":"poa1BL55g7Ucp6aUFo1CcjfFc7GDb46QM6NwJ4b5svW3W7o5","nonce":5,"parents":["7e5bfebc3d5a27b8176a4d70de6007a25d16a237442e4d5172005563472335af","eedbd0980560dbc64d328fb7b4780978cce9d0de20c32fe32dd305f0074b13e7"],"ts":1793146417,"cid":"poa-mainnet-1","sig":"3krRXVtaaii99orr2Bvb4PdZXoSuFQStPTQ3QA7pTYsqNQ2V2V686GZohxAjChLubywchtHR9moqy3N6FE93TJhc"},"checkpointed":{"height":95323,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T18:35:23.280Z","checkpoint_height":95323,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
