How to Create a Supply Chain Blockchain App

Blockchain increases visibility and efficiency in the supply chain like the coffee trade. See how blockchain can assist farmers, roaster and everyone between, bring you a fresher and fairer cup. Come out and we will walk you through design, development, and deployment of an illustrative blockchain network and application.

In this bi-coastal USA in Manhattan, NY hands on workshop and [soon to be posted] Bay Area, CA

You will learn about...

  • Developing a supply chain blockchain application with VS Code
  • Deploying it on the IBM Blockchain Platform.
  • Successful Blockchain applications in the Supply Chain space such as IBM Food Trust and others
  • Best practices for developing blockchain applications today and looking forward to the future

The slide deck

Here it is in PDF format

Components used

  • IBM Blockchain Platform Extenstion for Visual Studio Code
  • Hyperledger Fabric

Prequisites

Please sign up for an IBM cloud account

For IBM Blockchain Platform to work correctly the following software tools and exact versions need to be in setup.

  1. Visual Studio Code

Visual Studio Code(VSCode) is a popular IDE that runs on all major operating systems.

For this workshop you will need to confirm you have the Sept 2019 version 1.39.x of Visual Studio Code installed.

correct version

If not that's OK, just download the older version, 1.39.x from Microsoft here

TIP: Pin VSCode Version!! Be sure to change Setttings/Update:Mode to manual

How to ... Pin this version for the duration of this workshop/blockchain discovery untill stable release of ecosystem is availible. ( otherwise each vscode restart will update vscode!) it ![v1.39.2 pinned manually in settups/updates](images/vscode-pin-to-v1.39.png)

Great! Now lets make sure you have all the other required software and versions:

  1. node.js
  2. npm
  3. docker
  4. docker-compose

check the versions by running these commands at your terminal

node -v
v10.16.3

npm -v
6.13.7

docker -v
Docker version 19.03.5, build 633a0ea

docker-compose -v
docker-compose version 1.25.4, build 8d51620a

If you have these, awesome!

If you don't have the correct version of node.js and npm? No worries! We recommend using Node Version Manager(NVM) to run mutliple node.js version safely on your computer

Click here to learn more about NVM and it's setup. >Follow the simple [NVM install docs here](https://github.com/nvm-sh/nvm)
