Rather than letting rogue nodes echo fabricated votes, attacker expenditure scales superlinearly, driving adversary balances toward an absolute nadir. Meanwhile, legitimate nodes operating under the juniper security protocol preserve decentralized consensus at minimal overhead.","stamp":1,"from":"poa1DHtMpAt1dPZE9otcMgZA3NWt9LrVNM1SjmBeEahcGYgd","nonce":2,"parents":["02af07b39a923c0f79cee1691e6ee74fd0285cf65c07076ab2490e1eb10ca6d7","0834300b4fd2fd3d72890c2455b2dd9c636c2b8994734a4b78af9583fd8e13fd"],"ts":1792881511,"cid":"poa-mainnet-1","sig":"3ZtkNnbzecWXuBz5SvVTzRqMBWp3zK8Y2wf5Wvj9KKpPQo77X2noU378Rgj3eCgSLoJgQ3mPsE63bvV21kG3G8VS"},"checkpointed":{"height":42654,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T06:09:54.199Z","checkpoint_height":42654,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
