# Dispute

Opinion is built on the principle that **market outcomes must be accurate**. The dispute system gives every participant the power to challenge a resolution they believe is wrong — creating a transparent, community-driven layer of accountability.

By allowing anyone to dispute, Opinion ensures:

* **Accuracy** — incorrect resolutions can be corrected before payouts are finalized.
* **Fairness** — every trader has a voice.
* **Accountability** — disputors who are right are rewarded; frivolous disputes are discouraged through staking.

### Summary

* **Any user can dispute** a market resolution during the dispute window by staking $OPN tokens.
* **Two dispute categories**: *Wrong Result* (the outcome is incorrect) or *Too Early* (the event hasn't happened yet).
* You may also provide a **detailed written reason** — including reference URLs or evidence — for review.
* **One dispute per resolution.** The first user to file a dispute claims the slot. Once a dispute is filed, no further disputes can be submitted for the same resolution.
* **If your dispute is accepted**: you receive your stake back **plus** an equal reward in $OPN.
* **If your dispute is rejected**: your stake is forfeited.
* The required stake amount is shown on each market's dispute page.
* **Gas policy**: you pay your own gas for filing a dispute and claiming your reward.

### How It Works

#### Step 1 — A Market Resolves

When the proposed outcome is published and a **dispute window** opens - typically 2-hour long except some asset-price related markets. During this window, payouts are not yet finalized.

#### Step 2 — File a Dispute

If you believe the resolution is incorrect, you can file a dispute directly from the respective market page:

1. Select your dispute reason: **Incorrect outcome** or **Too early to resolve**.
2. Optionally, provide a detailed explanation with supporting evidence (e.g., links to news sources).
3. Stake the required amount of **$OPN** tokens. You will need to connect your wallet and have the required amount of $OPN ready. The exact amount is displayed on the market page.
4. Confirm the on-chain transaction.

#### Step 3 — Review

Once a dispute is filed, a review process will take place.

#### Step 4 — Outcome

| Scenario              | What Happens                                                            | Your Stake              |
| --------------------- | ----------------------------------------------------------------------- | ----------------------- |
| **No dispute filed**  | Resolution auto-finalizes after the dispute window expires              | N/A                     |
| **Dispute in review** | A dispute has been filed and is currently under review — result pending | Held                    |
| **Dispute rejected**  | The original result is reaffirmed — it stands                           | Forfeited               |
| **Dispute accepted**  | Original resolution is overturned — new result is applied               | Returned + equal reward |
| **Time out**          | Dispute succeeds automatically; market can be re-resolved later         | Returned + equal reward |

#### Step 5 — Claim Your Reward

If your dispute succeeded (accepted or timed out), you can claim your stake and reward from the market page. This is an on-chain transaction — you pay gas to claim.

### Timelines

Each market has its own dispute window durations. These are displayed on the market page when a resolution is proposed.

* **Dispute window** — the period after a resolution is published during which you can file a dispute.
* **Review window** — the period after a dispute is filed for a review process. The dispute automatically succeeds if the review process times out.

### Stake & Rewards

**Stake token**: $OPN

### Stake Requirement

The required stake amount is fixed at the time the first resolution is proposed for a market, and is calculated as:

**max(1% of market open interest, 1,000 $OPN)**

The $OPN amount is determined using the Binance OPN/USDT exchange rate at the time the first resolution is proposed.

**Example (assuming OPN/USDT = 1):**

| Market Open Interest | 1% of OI   | Required Stake                       |
| -------------------- | ---------- | ------------------------------------ |
| 200,000 USDT         | 2,000 $OPN | 2,000 $OPN                           |
| 50,000 USDT          | 500 $OPN   | 1,000 $OPN *(minimum floor applies)* |

The exact stake amount is always displayed on the market's dispute page before you commit.

*Note: Opinion reserves the right to adjust the stake percentage based on market category.*

**Reward structure**:

* **Dispute accepted or timed out**: you receive your full stake back, plus an equal reward — **2x your original stake** in total.
* **Dispute rejected**: your entire stake is forfeited.

### FAQ

**Q: How do I know if I can dispute a market?** A: When a market has an active dispute window, the market page will show the dispute option along with the remaining time and required stake amount.

**Q: What $OPN tokens do I need?** A: You need $OPN tokens in your connected wallet (EOA). The exact amount required is shown on the market's dispute page.

**Q: What happens if no one disputes?** A: The resolution is automatically finalized after the dispute window expires, and payouts proceed as proposed.

**Q: Can I dispute more than once on the same market?** A: No. Each resolution allows only one dispute. Once a dispute is filed, no additional disputes can be made.

**Q: What's the difference between "Incorrect outcome" and "Too early to resolve"?** A: Choose **Incorrect outcome** if you believe the outcome is incorrect. Choose **Too early to resolve** if the event the market is based on hasn't actually occurred yet — for example, a match that was postponed.

**Q: Do I pay gas fees?** A: Yes. Dispute actions — filing a dispute and claiming your reward — require you to pay gas on the BNB Smart Chain.

### Think a Resolution is Wrong?

Opinion's dispute system ensures no outcome goes unchecked. If you spot an error, you have the power — and the incentive — to correct it.
