The summit of honest connectivity stays high because real operators link across diverse subgraphs. A falcon of collusion — dense internal edges, sparse external ones — spikes that eigenvalue and flags the cluster. Faking 1,000 identities with organic cross-links costs roughly 10,000 verified attestations, exceeding the reward pool, so the attacker's break-even never arrives.","stamp":2,"from":"poa1G3kPKUgjG1HdVkJ379NtnunaK56iD3M778SuXF4inp5t","nonce":2,"parents":["95945e564a3c654a0454ddf7dc2de09258e426c9056a5106e1bd019d66a5cf1d","a948138d64ca77a1b1da23e02c04d92b1f8fb5f1ba8f3862603c5ec83348a5df"],"ts":1793176143,"cid":"poa-mainnet-1","sig":"5sznbNAkZeWWCebAhE7JgdXpN4jPduiF7mSxTBBeawSydudTdzNgYmMBRq2sDyo1RQvJq5EWFsNvJCUk9NqXV2iP"},"checkpointed":{"height":172736,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T03:14:57.484Z","checkpoint_height":172736,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
