Motivation

Purpose

Decentralized Election System

3 of 24

• Efficient Maintaining of the Voting System

    => The Election Commission can do their jobs digitally 

• Making the Job of Polling Agents Faster & Easier

    => The agents can quickly verify a voter

• Eradicating the Prospect of Fake Votes

    => Each voter can vote only once

Introduction (1 of 2)

Decentralized Election System

4 of 24

• Blockchain: Immutable distributed ledger
• Ethereum: Decentralized and open-source blockchain
• Smart Contracts: Immutable, verifiable, and autonomous pieces of code
• Solidity: Programming language to write smart contracts
• Node.js: Back-end JavaScript runtime environment
• Remix: An online IDE for Solidity
• jQuery: A fast, small, and feature-rich JavaScript library
• HTTP-Server: A simple, zero-configuration command-line static server
• Web3.js: A collection of libraries that allow you to interact with a remote ethereum node using HTTP, IPC or WebSocket
• MetaMask:  An extension for accessing Ethereum

•  Bootstrap: A free and open-source CSS framework
• ABI: It is an interface between two program modules, often between the operating system and the user programs
• InterPlanetary File System (IPFS): A protocol, hypermedia and file sharing peer-to-peer network for storing and sharing data in a distributed file system. IPFS uses content-addressing to uniquely identify each file in a global namespace connecting IPFS hosts
• TestNets: It is an instance of a blockchain which is used for testing and experimentation of applications without risking of losing funds
