PvP Coinflip Fairness

Our PvP Coinflip game utilizes a provably fair system where the public seed is not known until after the coinflip game has started. The result for each round is generated using the SHA-256 hash of three separate inputs:

• Server Seed:

  The server seed is a securely random value, generated when a round is created. The SHA-256 hash of the server seed is displayed to all players immediately after the round ends. Players can verify that the private seed revealed after the coinflip result is announced matches this SHA-256 hash.

• Public Seed:

  The public seed is the ID of an EOS block, generated after the countdown is finished. When the countdown ends, our system selects a block number on the EOS blockchain that will be generated in the near future. The ID of this block is used as the public seed. This ensures that neither the players nor our system know the data that will be used to generate the coinflip result until after both players have committed their bets.

• Nonce:

  The nonce is a number based on the round ID. The first round ever played has a nonce of 1, and this number increases by 1 for each new round.

This provably fair system guarantees that the outcome is fair and transparent for all participants.
