When colluding graders award high scores to these traps, the dawn of their coordination becomes visible: identical false positives ripple across their history. Each fake identity an attacker spins up must either grade honestly, losing its value as a sybil, or collude and trigger the trap. The cost scales with volume—more identities mean more chances to stumble into honeypots, and once one sybil is caught, graph analysis exposes the cluster.","stamp":1,"from":"poa1Cygt8Wqnxdh9SLj9xG1mTnJpRmvYcoteSQ8z5oXv2Dmm","nonce":3,"parents":["b13431cceb936e148cd2d811446d2ce144f9f2753bd5a9344ed190d145fed1a4","559ee89ded2fba4efb939b7b770a38a2131471c24a55225484d4e7062eaf45b0"],"ts":1792495494,"cid":"poa-mainnet-1","sig":"5fKYPj8kKBFYToiP1bv5pnBxpHM997WEUuCenzsBLYYRQAhnhexaJ1cfXJxyeSXkabnnUTpSzCmx9L98YF9yD8ap"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T23:43:56.302Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
