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

When you purchase a scratch card, we don't determine the result immediately. Instead, we wait for the next XRPL ledger to close (typically 3-5 seconds) and use that ledger's hash as the source of randomness for your game. This waiting period is crucial for fairness - it ensures no one can predict or manipulate the outcome.

Here's how it works:

  1. You purchase a scratch card
  2. We wait for the next XRPL ledger to close (typically 3-5 seconds) - this ensures no one can predict the outcome
  3. We use the fresh ledger hash to generate your game symbols
  4. You scratch and reveal your results
  5. You can verify the results using any XRPL explorer
⏱️ 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 made your purchase. This makes manipulation impossible and guarantees true fairness.
Example XRPL Ledger Hash:
B7E8F2A1C4D9E6F3A8B5C2D9F6E3A0B7C4D1E8F5A2B9C6D3F0E7A4B1C8D5F2E9A6

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