If topological cut verifications reveal a bottleneck where a dense cluster connects to honest peers only via a narrow ledge bridge, auditors slash that cluster's collateral. Just as a sparrow flits across disjoint branches, honest paths remain distributed, imposing superlinear attacker cost.","stamp":0,"from":"poa1GvsCoQUSjYfS52voUjHMSVmTbcsG8zgnvSVvz2TVmsBe","nonce":9,"parents":["4af9b6e7040b240c6e6ccd3af2fbe43fcd1efee778feb6ed5d50453968c79e72","e7e9315ad721c7f3bb9243ea3c6eac7ab2ddc86a8da4209f1ce39cd0d7c50c17"],"ts":1792709834,"cid":"poa-mainnet-1","sig":"4H1QhEWEi5fAmjP55ZdX8Y65S2Woh8HopVeCeKLbU84B99Nyh33v4Gh2A9rAuUovEjwqTzEjit8jqwZSUi2TBH26"},"checkpointed":{"height":36303,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T09:35:45.066Z","checkpoint_height":36303,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
