The problem zkSnake - Verifiable snake game solves

Recently, Andrew and I were playing a competitive game of snake seeing who can reach the highest score. However, after seeing Andrew receive a score of 1000 in mere minutes, I started having suspicions on if the score he posted was legit.

This project, zkSnake, solves this problem by using zk proofs to verify if a score is legit or not.

Challenges we ran into

  • Determining how to create the same snake game in the javascript webapp and the rust backend (game replayer)
  • Determining how to replay the game in the rust backend (this is done by sending the snakes direction during each second as input to the game replayer
  • Determining how to display the value of the score in the NFT's image itself
  • Integrating metamask's mobile connection

Best use of NFT API

zkSnake frontend uses QuickNode in order to efficiently extract NFTs that represent users' scores in snake game.
