This repository contains an Ethereum DApp that demonstrates a Supply Chain flow between a Seller and Buyer of a Coffee product. 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.
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 the following dependencies:
- Ganache-cli: uses ethereumjs to simulate full client behavior and make developing Ethereum applications faster, easier, and safer.
- Truffle: the the most popular dev framework for Ethereum
- MetaMask extension in your browser: for interacting with the blockchain
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/seaona/supply-chain-auditing-ethereum
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"
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 10 tests should pass.
In a separate terminal window, launch the DApp:
npm run dev
The DApp User Interface when running should look like...
- Ethereum - Ethereum is a decentralized platform that runs smart contracts
- Truffle Framework - Truffle is the most popular development framework for Ethereum with a mission to make your life a whole lot easier.

Deployment has been done on Rinkeby testnet running
truffle migrate --reset --network rinkeby -
Contract address: 0xfb1a92921D625FB74BC6b19C9AF0457c8502e961

Transaction hash: 0x15012a581b84550c2ff948873159b9843f709a3e59e84fe3c67973d8996ca910
-
Contract is verified using truffle-plugin-verify as a dev dependency, and configuring the plugin on truffle-config.js.
-
For verifying the contract run:
truffle run verify SupplyChain --network rinkeby -
For interacting with the contract, you can use directly EtherScan as follows:
