Enhanced Comparison of Consensus Algorithms on Distributed E-Voting Application Using Blockchain

Public elections are one of the bases upon which a democracy is built in many countries. Blockchain, an evolving and groundbreaking technology can be used to implement the elections. The online voting system along with trust among the voters drastically increases the number of voters participating in the election, in turn defining a true democracy. One of the most promising methods that are available to implement the election using Blockchain is Proof of Work. It is a necessary part of adding new blocks to the blockchain but consumes many computing resources. This is the precise time to move the application from Proof of Work(PoW) to other consensus algorithms that are available. This paper intends to compare the performance of the consensus algorithms based on the Voting system. The application is first built using Ethereum which uses PoW as the consensus algorithm. Then the voting system is built using the hyperledger sawtooth framework which offers PoET and pBFT. To compare the performance of both systems, metrics like throughput and latency are planned to be considered.
