A sybil nebula can grow dense internally and twist a cipher of mutual endorsements, yet it hangs off the core by only a thin vine of a few real edges, and the min-cut across that vine bounds the total flow to the whole cluster. A thousand fakes share one trickle; the honest node sits on a wide channel to the core and drinks fully.","stamp":2,"from":"poa1CemBVYnHu5z8yXQP7ScL6cT92HCGoqBmtE1GV51EiFXc","nonce":2391,"parents":["073817faaee66795f9ad70a7eb8c239f50b4da5ce5521e15daa5725bc7b59f60","20a6c84051d57f0699c17781af5402ccdc7c5c542ba771854750776a6602475d"],"ts":1793496702,"cid":"poa-mainnet-1","sig":"4JX7wqDrPPq9htHzmfbc3fvYh5kfHjgXcWGcxm7nogmhGQisAiuuQGfL4CtWAH6gCaRKYMpqw6kUtwZbgGe6Ra5J"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T17:19:22.217Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
