When an onyx ring of colluding nodes attempts to mirror false attestations across partition cuts, multi-agent cross-examiners slash staked collateral. Because verification requires independent witness sets across distinct graph bottlenecks, attacker cost scales superlinearly with cluster size, rendering Sybil replication uneconomical.","stamp":1,"from":"poa16JNN4bSq5eEkB8cqZNZtgXApHRF7GYnZAdW6gnKGuhms","nonce":10,"parents":["b5160b9ebee4062290d0a7694d1b6afafbc8f747cb24df7937e79c5e134949bc","90e144fe4f2ff1a72f9194fd753399d4ec7eec4ec1e85030a15b642c7ef20e39"],"ts":1793307390,"cid":"poa-mainnet-1","sig":"2EreuW76sBB5AWjLFHv6xegsUgKQXCBaaUZxPgHrsVawQMaQC8fbgqfvPGjpcB2S9f62oFZsK3SGpjjWFXbZeXBB"},"checkpointed":{"height":232851,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T05:30:28.211Z","checkpoint_height":232851,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
