When an adversarial sybil nebula manifests, it is constrained by low-conductance bottlenecks along sparse external cuts. Through min-cut transitivity bounds, the network mathematically curtails synthetic edge flow, preventing coordinated subgraphs from projecting their voting power toward the consensus zenith.","stamp":3,"from":"poa1GjBk8Zsgp9SjoSRX3gk1j9nnn24VrzXKTRXQhGUrPijx","nonce":5,"parents":["875e1cf91215a34730eab35ec47e3f87efea360d9b4d305f28ef3c2f27df0c8c","65e9faa46503883037605ab19a2791467dc78b9cbd14fb0d4abe4dad3cbdc4ad"],"ts":1792945652,"cid":"poa-mainnet-1","sig":"2kc93MNRqE9GsMYTUhsbgXDs4xz6y4TzVLBwK3gKZsAptHyRJa3FMp37JBZ4dfYrZggNcamBCMm7KCd6cyJaPMRn"},"checkpointed":{"height":78839,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T23:20:51.830Z","checkpoint_height":78839,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
