Katz lets you vote for your favorite candidate with greater anonymity. By leveraging recursive proofs with o1js and using Mina to settle the election results on-chain, your vote is kept private from the rest of the public while the overall election results can be known by anyone.
This project is based on some example code from the docs of Mina and o1js that can be found here.
Also the code in the directory contracts/src/voting/ is based on the code from Florian of O1Labs that can be found here. I modified it to fit my use case with a different data structure to keep track of the candidates vs of proposals as it was originally implemented in Florian's repo.
This project was built during ZK Hack Istanbul 2023, and I would also like to thank the team of O1Labs for assisting me during the hackathon with any questions and issues I had.
