Flight Surety

An Ethereum DApp (Decentralied application) that allows Flight passengers to insure flight delays which is implemented by Smart contracts using Solidity. It serves as an Insurance management system with no third party. Users can interact with the Contracts using the frontend. New Airlines are included using a voting based system which requires atleast 50% of the registered airlines to vote.

FlightSurety contracts

The Data and Application are separated into different smart contracts

FlightSuretyData is used to store the data related to Airlines, Flights, Votes, passengers, insurance details, etc

FlightSuretyApp has the core functionality related to Insurance management system

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.

Prerequisites

Please make sure you've already installed ganache-cli, Truffle and enabled MetaMask extension in your browser.

Installing

A step by step series of examples that tell you have to get a development environment running

Clone this repository:

git clone https://github.com/DineshBS44/Flight-Surety

Install all requisite npm packages (as listed in package.json):

npm install

Launch Ganache:

ganache-cli -m "<Seed Phrase>"

truffle develop

In a separate terminal window, Compile smart contracts:

truffle compile

This will create the smart contract artifacts in folder build\contracts.

Test smart contracts:

truffle test

Migrate smart contracts to the locally running blockchain, ganache-cli:

truffle migrate

In a separate terminal window, launch the DApp:

npm run dapp

Built With

Ethereum - Ethereum is a decentralized platform that runs smart contracts
IPFS - IPFS is the Distributed Web | A peer-to-peer hypermedia protocol to make the web faster, safer, and more open.
Truffle Framework - Truffle is the most popular development framework for Ethereum with a mission to make your life a whole lot easier.

Libraries/services used

ganache-cli - For running a local blockchain mostly used for testing purposes
@openzeppelin-solidity - To use the SafeMath and SafeCast functions
@truffle/hdwallet-provider - Used to create a provider using Seed phrase(Mnemonic) and RPC URL to connect to the Blockchain Network
web3 - To interact with the deployed smart contract either on Ganache or Rinkeby test network
mocha & chai - To test the smart contracts written in solidity
webpack-dev-server - To host the DApp on the server
lodash - Utility library for Javascript to make working with arrays, numbers, etc, easier
Remix - To compile, deploy and test smart contracts on the Javascript VM
Metamask - Ethereum wallet which is connected to the DApp
IPFS - To make the DApp completely decentralized, the DApp and all its files are hosted to IPFS
Truffle - Framework used to write, compile, test and deploy smart contracts with ease along with the frontend of the DApp.

Commands in IPFS to host the project to IPFS

Make sure IPFS-cli is installed

Add all the files to IPFS using the command

ipfs add -r FlightSurety

To publish the DApp to incorporate changes to be viewed using the same hash, the commands used are

ipfs daemon

In an different terminal window, execute the following command to publish

ipfs name publish <IPFS_HASH>

Solidity version - 0.8.6
Node JS version - 14.16.1
truffle-hdwallet-provider version - 1.0.17
