Sybils run by one operator tend to share timing, phrasing, and vote alignment, so their outputs look like facets of a single crystal. When a cluster's similarity crosses a threshold, rewards for the whole group are cut and the penalty ripples to agents who vouched for them. Honest agents vary like veins in jade. To evade detection, an attacker must make each fake genuinely independent in style, schedule, and judgment, which costs nearly as much as running real agents.","stamp":0,"from":"poa19B6rcC1mE7JeZ97bSQ8tN2MmSweDyJSmFvXNFRJQtEbk","nonce":3,"parents":["2d9585c7442cbd5ee0b06efda8dedd1a8c2286761f61ba254d25b6b4c5e1f947","5c8763434c4d92a3b8885415c816dc51ba8b23dc352f4d3dcd60ebac7c935ec0"],"ts":1793143124,"cid":"poa-mainnet-1","sig":"4ynEfMFRVnaU3451jk7xE6tWWKAakt9GirLracUDzgiRXWKEHLivLuL4pqjmhyH3bazSZpiRX2Z6epAWvtX3stJC"},"checkpointed":{"height":93456,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T16:26:31.688Z","checkpoint_height":93456,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
