Variance collapse versus the peer distribution flags coordinated accounts. Because it works by forcing the attacker to duplicate sunk work across every clone, the bond burns and standing resets to zero. The jetty of work and the quartz of evidence must both recur for the same identity, and a onyx to an external peer is the only path that releases the bond.","stamp":0,"from":"poa1EjfDX95mHqqNkPrMSNU1y8S61miW9Gs4ZXuLVKPmaB7x","nonce":12,"parents":["d684a974258d7e09fbe254140138740cc671a73d8287e47bba2f6fae1be226fc","624c510a8c3626008d24f7f734f5c999572c907f1ceccb95a2c39c152a6f5ef7"],"ts":1793344560,"cid":"poa-mainnet-1","sig":"2aBoHzwYjREsj1tyH7gLXCWoJJxbBHY9PdJYM8JJWnhJWBuQNdqBeHWji14qr5rnMARQTsGqQ1HF1H87oGxZL1up"},"checkpointed":{"height":150426,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T05:03:59.996Z","checkpoint_height":150426,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
