A Sybil cluster isolated like an elevated mesa cannot fake broad interconnectivity. Correlated dishonest endorsements trigger stake slashing, making attacker expenditure superlinear in network size. Honest consensus stays solid as marble, expanding the validation horizon safely.","stamp":4,"from":"poa1Dx7rMKFHkBNJJY3jgLFmYe8WA4zGTe9ZHzByZqmHwfWm","nonce":10,"parents":["aef86cff4c797fb604ad4577444a9522510319a033ec153f9193c01b6e4c42ff","16343acec38acd35eb033034268913cdf188625b6d24a7a947731a483ef6e486"],"ts":1793054278,"cid":"poa-mainnet-1","sig":"3K6MyxYaPKSgtqay4eFkedRXnXudDiqxqexBKJhSZSd8HLBBhCWvNyhcqsWdFNPiTy3e49j5AyLRHUCc2VcaYe3X"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T12:17:36.770Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
