The problem BlockVotes.eth solves

Prevents Vote count manipulation in Online voting as it is BlockChain based (Immutable data).

(Note: We've used this project previously for a hackathon at our University and now plan to submit it here with a few minor bug fixes and frontend changes etc.)

Challenges we ran into

There were not many video guides so we had to read the documentation a lot and ran into many errors during the testing, and deployment phase, for e.g: Had some runtime errors while deploying the smart contract onto the Ropsten testnet so shifted to the Rinkiby test net and the other things were while testing the smart contract we incurred a few edge cases which had to be addressed with new test scripts by observing and understanding what might have gone wrong.
