Provably Fair

Jackpot Details

Our platform ensures fairness and transparency through a provably fair system (PF vNext). Here's how it works:

Server Seed - A securely generated random value. The SHA-256 hash is revealed at round start.
Public Seed - Uses EOS Block ID fetched at spin time - unpredictable by anyone.
Bet Order - Bets are sorted by actual Solana blockchain order (slot, txIndex, signature).
Winner Selection - Ticket = SHA512(seeds) % totalLamports. Winner is found by cumulative lamports walk.

PF vNext provides full end-to-end verification: anyone can independently verify the winner.

const crypto = require("crypto");

// 1. Verify server hash

const hash = crypto.createHash('sha256').update(serverSeed).digest('hex');

// 2. Calculate ticket (lamports-exact)

const combined = `${serverSeed}-${publicSeed}-${gameId}`;

const sha512 = crypto.createHash('sha512').update(combined).digest('hex');

const seedInt = BigInt('0x' + sha512.slice(0, 16));

const ticket = seedInt % totalLamports;

// 3. Find winner by cumulative walk

let cum = 0n;

for (const bet of orderedBets) {

cum += BigInt(bet.lamports);

if (ticket < cum) { winner = bet.wallet; break; }

}
