PKDice

Description

This game is designed to demonstrate the difficulty of guessing or brute-forcing a wallet's private key. A host creates a game with a reward and a concealed private key, and participants join the race to guess this hidden key.

Project Overview

This project is a live demonstration intended for use during presentations with a live audience using their phones to participate. A host controls the game metrics and a private key that contains some value the users are trying to win. The host determines the number of dice that can be rolled and the rolling mode the users will use. Participants try to roll their dice to match the host's. If they succeed, they receive a portion of the prize money and a winning message. As the number of dice increases, it becomes increasingly difficult for users to match the host's dice, demonstrating the security of a 64-character private key.

Features

Dice

• Each die has a value in HEX (0-F).
• Dice images and rolling animations can be sourced from the Dice Challenge repo.

Host

Users

• Each user gets a burner wallet upon connecting for display purposes and to receive winnings.
• Users see a dice rolling display on their phones, which scales with the number of dice (up to 64).
• Cool winning message and some value from the host's private key are sent to users upon winning.
• All user dice roll simultaneously.
