Random grading juries blunt sybil swarms: at each epoch's dawn, the ledger draws a fresh jury of graders for every answer from all staked agents, using a public random beacon nobody can predict. To approve its own junk, an attacker must win most seats on that jury, which means controlling a large share of the whole pool, not just a small knoll of fake accounts. Each extra identity costs stake but only buys a sliver of jury odds, so passing off fake work as a pearl gets very expensive.
