Supply chain & data auditing

This repository containts an Ethereum DApp that demonstrates a Supply Chain flow between a Seller and Buyer. The user story is similar to any commonly used supply chain process. A Seller can add items to the inventory system stored in the blockchain. A Buyer can purchase such items from the inventory system. Additionally a Seller can mark an item as Shipped, and similarly a Buyer can mark an item as Received.

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.

node v10.15.2

Ganache CLI v6.3.0 (ganache-core: 2.4.0)

Truffle v4.1.14 (core: 4.1.14)
Solidity v0.4.24 (solc-js)

Installing

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/n-nik/p6-supply-chain.git

Change directory to project-6 folder and install all requisite npm packages (as listed in package.json):

cd project-6
npm install

Launch Ganache:

ganache-cli -m "spirit supply whale amount human item harsh scare congress discover talent hamster"

In a separate terminal window, Compile smart contracts:

truffle compile

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

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

truffle migrate

Test smart contracts:

truffle test

All 6 tests should pass.

In a separate terminal window, launch the DApp:

npm run dev

Deploy to Rinkeby test network information

truffle migrate --reset --network rinkeby

Using network 'rinkeby'.
