Supply-Chain-Management---BlockChain-UseCase

Supply Chain Management System

“Supply Chain Management”, Using this supply chain management a user can view the journey of mobile phone from the manufacturer to it's user. Through blockchain technology we can create a trusted, transparent system of this supply chain.

The API performs following functions:

Registering Stakeholders(Manufacturer, Distributor and User) by providing Name, Password and type. It returns UserID.
Login user with the User Id and Password.
Register the mobile for the auction.
View the mobile and Track the owners and journey in the supply chain.
Transferring the ownership of the mobiles.

Tech Stack

This supply chain management system uses multiple technologies:

Ethereum Blockchain- Ethereum Blockchain Stack (Tool used: Geth)
VS-Code - Text Editor for writing code
Twitter Bootstrap - great UI boilerplate for modern web apps
node.js - evented I/O for the backend
Express - fast node.js network app framework @tjholowaychuk
web3.js - Ethereum Javascript API
jQuery

And of course Dillinger itself is open source with a public repository on GitHub.

Installation

Node.js v6+ to run.

$ curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash -
$ sudo apt-get install -y nodejs

Installing Ethereum Package:

$ sudo apt-get install software-properties-common
$ sudo add-apt-repository -y ppa:ethereum/ethereum
$ sudo apt-get update
$ sudo apt-get install ethereum

Testing

Want to contribute? Great! Try these commands to work on this:

Open your favorite Terminal and run these commands.

Create local chain:

$ geth –rpc –rpcport “8085” --rpcapi=”db,eth,net,web3,personal,web3” --datadir data –networkid 123 –nodeiscover –maxpeers 0 init genesis.json

Launch Geth Console:

$ geth –rpc –rpcport “8085” --rpcapi=”db,eth,net,web3,personal,web3” --datadir data –networkid 123 –nodeiscover –maxpeers 0 console

Create new account (in geth console):

personal.newAccount(“passphrase”)

Mine some ether

miner.setEtherbase(personal.listAccounts[0]); miner.start()

Deploy the smart contract

loadScript(“mobilechain.js”)

P.S.: mobilechain.js file is in the directory and it's the web3 deploy form of smart contract.

Unlock Account 0th using this syntax

personal.unlockAccount(address, “password”, timeout)

P.S.: You can also use eth.accounts[0] in place of address for the 0th account in the geth.

Running node server instance using another terminal window

$ nodemon server.js

P.S.: Here I'm using nodemon for testing purpose.

Verify the deployment by navigating to your server address in your preferred browser.
