Commit Reveal Voting Contract With Solidity Keccak-256 hash

Commit-reveal schemes are necessary in applications such as gambling, voting, and auctions. This video demonstrates how to implement a simple commit-reveal scheme using Solidity and Keccak-256. In the commit phase, users commit a hash of their vote. In the reveal phase, users provide the original vote and the salt. If the hashes match, then the smart contract counts the vote.
