Provably Fair Verification

At Rolxio, transparency is a priority. Our in-house games use the Provably Fair system, allowing any player to verify the fairness of each result.

How does it work?

Before each bet, the server generates a Server Seed and a hash of it. Combined with the Client Seed (player's seed) and the Nonce (counter), the result is determined cryptographically.

Before the bet

The Server Seed hash is displayed. It is immutable and proves that the result was already defined before you bet.

During the bet

The Client Seed (which you can change) and the Nonce are combined with the Server Seed to generate the result.

After the bet

You can reveal the Server Seed and verify that the hash matches the one displayed before. Any SHA-256 calculator can confirm.

Verification Example

See below how the result is calculated. You can reproduce this in any language to confirm fairness:

JavaScript

// 1. Bet data
const serverSeed = "a1b2c3d4e5f6...";  // Revealed after the round
const clientSeed = "minha_semente";   // Defined by you
const nonce      = 42;                  // Bet counter

// 2. Generate HMAC-SHA256 combining the data
const crypto = require("crypto");
const message = clientSeed + ":" + nonce;
const hmac = crypto
  .createHmac("sha256", serverSeed)
  .update(message)
  .digest("hex");

// 3. Convert first 8 hex chars to number
const decValue = parseInt(hmac.slice(0, 8), 16);

// 4. Calculate result (example: Crash)
const e = 2 ** 32;
const result = (100 * e - decValue) / (e - decValue);
const crashPoint = Math.max(1, Math.floor(result) / 100);

console.log("Crash Point:", crashPoint + "x");

// 5. Verify hash (compare with the one shown before the bet)
const hash = crypto
  .createHash("sha256")
  .update(serverSeed)
  .digest("hex");
console.log("Server Seed Hash:", hash);
// If this hash == hash shown before → result is fair ✓

You can verify any bet using the code above. Simply replace the Server Seed, Client Seed and Nonce values with the data shown in your bet history.
