Provably Fair Explained

Understand how provably fair technology ensures transparent and verifiable game results

Updated over a month ago

Overview

Provably fair means you can verify that every online casino game result is random and unmanipulated. Unlike traditional online casinos where you must trust the operator, OPDuel provides mathematical proof that outcomes are fair.

How It Works

Before You Play

  • A random outcome is generated using cryptographic technology

  • This outcome is “locked in” before you place your bet

  • Server seeds, client seeds, and nonces determine the result

After You Play

  • You can verify the outcome matched the pre-generated result

  • Check the cryptographic proof for any bet

  • Confirm no manipulation occurred

Think of it like this: The game decides your result before you bet. It shows you proof. You can check the proof later.

Key Components

Server Seed

  • Random string generated by OPDuel

  • Hashed and shown to you before betting

  • Cannot be changed after revealed

Client Seed

  • Random string you can customize

  • Adds your own randomness to the outcome

  • Change it anytime for additional security

Nonce

  • Counter that increases with each bet

  • Ensures each result is unique

  • Prevents outcome prediction

How to Verify a Bet

  1. Open your bet history

  2. Click on any bet to view details

  3. Look for “Verify” or “Provably Fair” section

  4. View the seeds and nonce used

  5. Use the verification tool to confirm fairness

The verification shows that the outcome was determined before you bet, using the exact seeds displayed.

Why This Matters

Traditional Casinos

  • You trust the operator

  • No way to verify fairness

  • Results could be manipulated

OPDuel (Provably Fair)

  • Mathematical proof of fairness

  • You can verify every outcome

  • Impossible to manipulate results
