How LuckyHash Works

Learn about our provably fair scratch card system powered by the XRPL blockchain

? What is LuckyHash?

LuckyHash is a provably fair scratch card platform built on the XRP Ledger (XRPL). Unlike traditional online lottery systems, every game result on LuckyHash is determined using real blockchain data, making it impossible for anyone—including us—to manipulate the outcomes.

Our scratch cards come in different token types including XRP and CSC, each offering different prize pools and gameplay experiences.

1 Provably Fair with XRPL

Blockchain-Powered Randomness

Every scratch card uses XRPL blockchain data for provably fair randomness. We wait for the next XRPL ledger to close (typically 3-5 seconds) and combine it with unique data to ensure no one can predict or manipulate the outcome.

How Results Are Generated:

Regular Purchased Cards

Formula: SHA256(Transaction Hash + Ledger Hash)

Your payment transaction hash is combined with the next XRPL ledger hash. Since your transaction hash didn't exist before you paid, this ensures complete fairness.

Gift Cards & Free Cards

Formula: SHA256(Purchase ID + Ledger Hash)

A unique purchase ID is combined with the next XRPL ledger hash. This ensures each gift card redemption gets a unique result, even when multiple cards are played simultaneously.

The Process (All Card Types):

  1. You play a scratch card (purchase or redeem a gift)
  2. We wait for the next XRPL ledger to close (typically 3-5 seconds) - this ensures no one can predict the outcome
  3. We combine your unique data (transaction hash or purchase ID) with the fresh ledger hash using SHA256
  4. The resulting hash is converted into your game symbols
  5. You scratch and reveal your results
  6. You can verify everything using XRPL explorers and our verification system
⏱️ Why We Wait: By waiting for the next ledger, we ensure that your game result is based on blockchain data that didn't exist when you started playing. Combined with your unique transaction or purchase data, this makes manipulation impossible and guarantees true fairness.
Example Process:
Transaction Hash: A7B3C1D9...
+ Ledger Hash: B7E8F2A1...
= Derived Hash (SHA256): C9E5D2F8A4B7E1C3...

The derived hash gets converted into symbols for your scratch card grid. Each pair of characters becomes one symbol, ensuring complete transparency and fairness for all card types.
