Winner Selection

The winner selection process in FunStake is designed to ensure fairness and transparency, leveraging the security and randomness capabilities of the NEAR Protocol.

Here’s a step-by-step breakdown of how we select the winner(s) for each game session:

1. Random Number Generation:

   • At the end of each game session, FunStake uses NEAR’s randomSeed() function to generate a cryptographically secure random seed. This ensures that the random number generation process is both secure and unpredictable.

   • The random seed is converted into a Uint8Array, an array of 8-bit unsigned integers, which is then used to build a large BigInt value. This process combines all the random bytes into a single, large random number.

2. Calculating the Winning Number:

   • The large BigInt value generated from the random seed is then subjected to a modulo operation with the total number of tickets in the game session. This operation ensures that the winning number falls within the range of available tickets. For instance, if the total number of tickets is 100, the winning number will be between 0 and 99.

   • If there are no tickets (to prevent division by zero), the range defaults to 1. This ensures that the winner selection process is always valid.

3. Determining the Winner:

   • Once the winning number is calculated, the protocol iterates through the tickets of all participants to find which user’s ticket range includes the winning number. Each participant’s ticket range is determined by their accumulated tickets, starting from the cumulative total of previous participants.

   • For example, if Participant A has 50 tickets (range 0-49) and Participant B has 30 tickets (range 50-79), and the winning number is 55, Participant B would be the winner since 55 falls within their ticket range.

4. Multiple Winners (Future Feature):

   • Currently, FunStake supports one winner per game session. However, the protocol is designed to be flexible and can be adjusted to support multiple winners in the future. This will allow the final prize to be shared among multiple participants, enhancing the inclusivity of the game.

By utilizing NEAR’s robust random number generation and a transparent selection process, FunStake ensures that every participant has a fair chance of winning based on their ticket count and timing of their deposits.
