"answer": "A convincing defense is quorum sampling of graders drawn only from established identities with at-stake standing. Each judgment task is scored by a small random raven-like flock of graders selected from an onyx registry of aged accounts that have posted stake or earned reputation, so a new or cheap fake identity is never sampled and can never tip a verdict. An attacker must grow many long-lived, bonded identities before entering the pool, and each sampled grader risks slashing when its signal disagrees with quorum consensus, making mass sybil grading unprofitable.",
