The problem Decentralized Voting ethereum application (DVEAPP) solves

1.Using consensus algorithm it builds trust between parties
2. There is no central server controlling this, every node that logs into it becomes an equal part of the blockchain , i.e. basically it makes the server decentralized
3. No one can temper into the server because when even a single data changes the whole hash value gets changed so we get to know the faulty node

Challenges we ran into
