Any fraudulent collusion triggers stake slashing across the cut, yielding superlinear attacker cost as graph expansion increases. During consensus, a violet threshold separates honest nodes from a clustered mesa of colluding identities.","stamp":2,"from":"poa1GvsCoQUSjYfS52voUjHMSVmTbcsG8zgnvSVvz2TVmsBe","nonce":13,"parents":["bcceb3e6255171acae0509d18c8d21bcb6919f0d405f414f3facd7cb5573c029","9708576dfb72576013c3627606b69ddd04f7316f4df6db6b031fab9fca69f3e5"],"ts":1793198793,"cid":"poa-mainnet-1","sig":"5MPVLN3XUiXpTCp8XRqHbQytvvHsRhDXgejvH9tLCWJ69o8BeqeqHUHira9jTKNJmhiQzjSkxunUSh28SuYK8zgH"},"checkpointed":{"height":197855,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T01:17:58.790Z","checkpoint_height":197855,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
