# Market Resolution & Challenge System

### Resolution Process

Yamata uses a challenge-based resolution system to ensure accurate results:

1. **Initial Resolution**: Market creator submits the winning outcome
2. **24-Hour Challenge Period**: Window for disputing incorrect results
3. **Economic Incentives**: Challengers stake tokens; correct challenges rewarded
4. **Finalization**: After challenge period, result becomes final

### Resolution Criteria

Markets can be resolved when:

* Event has occurred (past tResolve)
* Outcome is objectively verifiable
* Market creator has submitted result
* 24-hour challenge period has passed (if challenged)

### Cancellation Scenarios

Markets may be cancelled if:

* **Fewer than 2 outcomes** have commitments (unresolvable)
* **Flagged for rule violations** during challenge period
* **Event cancelled** or made unresolvable in real world
* **No winning outcome** (edge case)

In cancellation scenarios, all participants receive full refunds.
