Optimization of Blockchain Based E-voting

Modern technology has created the need for information flow to be fast and effective. we have been able to reach this through the internet; the medium, that is, the internet has expedited every folks, by creating the communication cheap and quick. One such innovative technology is blockchain. Having the properties such as immutability, integrity and decentralized architecture, one of the prospective application of blockchain is e-voting. The objective of e-voting system using blockchain is to facilitate transparent, fair and verifiable approach. But the existing e-voting systems using blockchain take more time to reflect the vote casted by the voters as the number of voters increases and make the system slow. In this paper we propose a system which uses a consensus algorithm called PoA to minimize the time for authentication, mining and verification of casted votes. The Proposed system which replaces the PoW consensus algorithm, in existing system, with PoA consensus algorithm, proved to be faster than existing system by more than 9 seconds. Thus this paper highlights how the existing e-voting system using blockchain is slow and how the proposed system optimizes the time required and makes the system faster.
