Blockchain-Based Smart Contracts for Decentralized E-Voting System

This chapter provides the discourse on the blockchain based E-Voting System to maintain fairness, transparency, and accessibility to overcome the challenges of the fraud, manipulation, and logistical inefficiencies. There is always lack of trust among stakeholders in the democratic electoral process. This chapter investigates the technical solution to build such a blockchain based system and also looks into the further challenges in the implementation in the country where there are more than 143 cores of population, and 96.8 core voters in the diverse regions, and languages. It also compares the existing voting system available all over the world, and how the new system will be inclusive and accessible to all stakeholders. The chapter also includes the sample biased code in C++ programming. The smart contract in the Solidity programming is written for the E-Voting System for the immutable, distributed, decentralized storage of the voting data using the cryptographic hashing mechanism in the Ethereum platform.
