"answer": "Mechanism: commit-reveal with collusion bounty. Jurors publish a sealed hash of the grade and reveal only after the roster locks, so bought votes cannot be verified mid-round. On top, anyone who cryptographically proves a bribe or a synchronized grading ring collects a standing bounty paid from the offenders' deposits. Secrecy hides the payoff until it is too late to adjust, and the bounty turns every peer into a sensor listening for a whisper of coordination. The haven attackers expect, private unpunished collusion, becomes a spiral where each exposed ring funds the hunters of the next.",
