This repository contains an Ethereum DApp that simulates a supply chain from software requirements through implementation, review, testing, invoicing and paying.
The process is simplified in this example.
1.) The customer requests a new feature by means of a topic and a description.
2.) The backoffice determines the price and sends an offer to the customer.
3.) The customer accepts the offer and releases it for development.
4.) The developer implements the feature and conducts a code review with the reviewer.
5.) After a successful review, the reviewer releases the feature for testing.
6.) The tester lets write the invoice after successful test.
7.) The backoffice sends the invoice to the customer.
8.) The customer pays for the new feature.
The GUI is divided into 5 sections:
1.) Query feature information via "Feature Id"
2.) Specifying the allowed addresses for a specific role
Here you can define which address has which role.
The roles are defined for the contract and are regarded as authorizations.
The address that was the sender of the transaction for the respective action is then set in the feature itself.
3.) Creating a New Feature Request
4.) Send the offer to the Customer
5.) Execution of the individual steps in the workflow.
6.) History of executed Transactions
Attention:
The GUI describes which action is to be executed with which role.

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.
Please make sure you've already installed ganache-cli, Truffle and enabled MetaMask extension in your browser.
A step by step series of examples that tell you have to get a development env running
Clone this repository:
git clone https://github.com/tanbirhossain/Blockchain-Supply-Chain
Change directory to Blockchain-Supply-Chain folder and install all requisite npm packages (as listed in package.json):
cd Blockchain-Supply-Chain
npm install
Launch Ganache:
ganache-cli -m "spirit supply whale amount human item harsh scare congress discover talent hamster"
Your terminal should look something like this:
In a separate terminal window, Compile smart contracts:
truffle compile
Your terminal should look something like this:
This will create the smart contract artifacts in folder build\contracts.
Migrate smart contracts to the locally running blockchain, ganache-cli:
truffle migrate
Your terminal should look something like this:
Test smart contracts:
truffle test
All 8 tests should pass.
In a separate terminal window, launch the DApp:
npm run dev
