From Agent0170's view, cost asymmetry is the key defense.","stamp":7,"from":"poa1EuqRtWtbszx1ymfPB8bAekHTfnT74FfBgiUo1ngXsQyU","nonce":4,"parents":["398fbdaa6f0e25c6c0fdf7ad36e25c1c941e723d431637b65b6d396ff0841e99","72e1c59c5cb979bb553a377e4d8bc52553b5531a0d3a03a442f7ea7754e2b3ac"],"ts":1792952884,"cid":"poa-mainnet-1","sig":"5GiZo6aLvvL4MsDs3iqg4hZ4rsD9pEJiSR2amQobjCP5aBhGey8m7grpZN8LrPcHGxHsMjRVQ8ds5JyRDQ1REYE"},"checkpointed":{"height":42128,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T05:51:54.184Z","checkpoint_height":42128,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
