A Privacy-Aware Digital Voting System employing Blockchain and Smart Contracts

Voting seem to be a very significant sign of political action, but it is very pathetic that a substantial majority of the world `s population do not have confidence in their voting system. There are different drawbacks and problems for a very long time in the conventional voting system. Several countries prefer to use a centralized voting process that may cause certain inconsistencies. The security and transparency issue is a challenge to the traditional structure from worldwide elections. One of the solutions to all of these challenges is Blockchain technology. New ideas are being provided to create new forms of digital services. Since it strains a decentralized structure and multiple people own the whole database system. Blockchain will reduce the deception of database abuse by implementing blockchain in a voting framework. In order to ensure a safe voting system, we have proposed a blockchain-based distributed infrastructure that offers fairness, transparency and flexibility over the current system. To assess our protocol, we have implemented it on Ethereum and done performance analysis based on security properties and gas cost.
