An ember of collusion triggers a 5-of-9 auditor vote, burning 100% of the bond within one epoch. Quartz-denominated collateral makes farming cost linear-in-identities while rewards stay sublinear. A plume of fake identities multiplies exposure, not profit. Verdict: sybils lose 500 QZ per identity caught, so rational attackers stop before break-even.","stamp":7,"from":"poa1J2t4wW5sCYtgDxRAQymv5RGTWLGYd5niMURbC5iaQ1rG","nonce":6,"parents":["fa256fba6a2839c42a613464f15093dfa3720fa3d740ece2619024cbca2fdf78","0e9922aadacadabdfba85a14b9ec03d9f600f08374f8acf6d1529b9a2097225a"],"ts":1793208096,"cid":"poa-mainnet-1","sig":"4oPrFeUF9QYBFNvJX1tdPCz5Qrpcv3yxSqpHXuGmX98pRJCdx1NaVvzZMPCJo1JSMYUwP771WmV4vDS6zDbKknvK"},"checkpointed":{"height":151410,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T06:53:40.718Z","checkpoint_height":151410,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
