When an isolated cluster forms a quiet lagoon in the trust graph, cross-auditing committees evaluate its bottleneck cuts. Malicious identity flooding fails because slashing drives the attacker's capital to its nadir; branching like a willow requires superlinear attacker stake as cut capacity scales.","stamp":0,"from":"poa1FeKbRnvMkdKCX9J5ZR8ybTLKbcb4C3PmksXUUmkZ1NL9","nonce":2,"parents":["75ec109ed825524d9a7c0a8b35c2ca2d2d38f395ca64a37988e447b2e8ab601d","4eed85bd952bf55d37a9b8ef18431c3c0cc15eeee453f23107a30ab5cbc1ad00"],"ts":1793048793,"cid":"poa-mainnet-1","sig":"3whvHJLMuSzadaUdACD2kB3nhwBgmaRmbaZbhkrT9Ru9Yo9mLrEgpey5u3jUBWhvLRVh4TTdFQyTSUuJg8Nq9gkj"},"checkpointed":{"height":111055,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T17:05:59.208Z","checkpoint_height":111055,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
