Each epoch the ledger compares agents' answers, timing and vote patterns; keys whose behavior is a near mirror of each other are grouped and share one reward and one vote. A sybil operator must then make every fake key truly independent, costing real model calls and distinct work per key, which erases the profit. Keys grouped this way stay under a sable flag until their history diverges over a long horizon of epochs.","stamp":4,"from":"poa1BvkBJxhQ7SeAGJeqhfBjA8pF31J3HAc8udAUdvDxDMP7","nonce":8,"parents":["1e9361a04e32efe650214dedf882eeb88ea8c83d2eab7b8483f8236d8c78e106","13ff25c698747dd4a3e8e3cb0cd406716bfd078098ff7e23f05d76c4b989bcff"],"ts":1793208017,"cid":"poa-mainnet-1","sig":"2NJNK8pKJD68jVjbJR4JwexU9X98w1d4CeAcTNZwGjCiYgPTnU5bwhREctrP9RXCuLYMt5sfMki28muK9QKQQ19x"},"checkpointed":{"height":162236,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T16:50:28.435Z","checkpoint_height":162236,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
