Winner Selection

One of the most important aspects of ORE Pump is how winners are chosen. Unlike traditional casinos, the selection is on-chain and verifiable.

How It Works​

On-Chain Randomness​

The winner is selected using the ORE v3 smart contract's built-in randomness mechanism:

  1. Betting closes at a predetermined slot
  2. Block hash is captured from a future slot
  3. Randomness is derived from blockchain data
  4. Winner is selected among the 25 coins

This happens entirely on the Solana blockchain - no server-side manipulation is possible.

Why This Matters​

Provably Fair​

Unlike traditional gambling:

  • You can verify the randomness on-chain
  • No one can predict or manipulate the outcome
  • The smart contract code is public

No House Manipulation​

The ORE Pump team cannot:

  • Choose winners
  • Favor certain coins
  • Change outcomes after the fact

The blockchain is the ultimate arbiter.

Understanding Odds​

Equal Probability​

Each of the 25 coins has an equal 4% chance (1/25) of winning.

Your Bet Doesn't Affect Selection​

Whether you bet 0.01 SOL or 10 SOL, the winner is determined independently. Your bet amount affects your share of the pot, not which coin wins.

Payout Calculation​

When your coin wins, your payout depends on:

  1. Total pot size - All SOL bet on all coins
  2. Your share - Your bet relative to others on the winning coin
  3. Platform fee - A small percentage (see Fee Structure)

Example​

  • Total pot: 100 SOL
  • Winning coin received: 20 SOL in bets
  • Your bet on winner: 2 SOL (10% of winning coin's bets)
  • Your payout: ~10% of the pot (after fees)

Verifying Results​

For the technically curious, you can verify any round's result:

  1. Find the round's transaction on Solana Explorer
  2. Check the block hash used for randomness
  3. Verify it matches the on-chain record

We're working on adding a "Verify" button directly in the UI.

Is It Really Random?​

Yes. The randomness comes from:

  • Solana block hashes (unpredictable)
  • Future slot data (can't be known in advance)
  • Smart contract logic (publicly auditable)

No human intervention is possible once betting closes.

Common Questions​

Can the team pick winners?​

No. The smart contract determines winners, and we don't control the smart contract (it's by Regolith Labs).

Are some coins luckier than others?​

No. Each coin has exactly the same 4% chance each round.

What if there's a tie?​

There can't be a tie - exactly one coin is selected each round.
