Drawing Numbers

🎯 Introduction​

At the heart of every lottery is its random number generation - the crucial mechanism that determines winners. While traditional lotteries rely on central authorities, Eat the Pie uses Witnet's oracles on World Chain to ensure true randomness. This creates a provably fair system where no single entity can influence the outcome.

🔢 The Drawing Process

Let's break down the intricate process of how random winning numbers are generated:


Eat The Pie Process

1. 🚀 Initiating the Draw

- command initiate-draw using the CLI app
  • At a predetermined block (let's call it block X), this function is called to start the drawing process.
  • The function will call the witness contract to ask to generate random bytes.
  • Ref: smart contract.

2. 🎲 Completing the Draw

- command complete-draw using the CLI app
  • Once the witnet contract has generated the random numbers, function: setRandomAndWinningNumbers() can get called.
  • This will fetch the randomness from the witnet contract and set the winning numbers.
  • Ref: smart contract.

3. 🏁 Finalizing the Draw

- command calculate-payouts using the CLI app
  • The function calculatePayouts() can now get called, which settles the prizes and winners.
  • The round is over and users can claim their prizes.
  • Ref: smart contract.
