IBM Blockchain Fabric

Install docker and docker-compose following this link.

Check upon the successful installation of docker. I am running this demo with the following docker configuration.

docker --version
docker-compose --version

Docker version 19.03.5, build 633a0ea
docker-compose version 1.24.1, build 4667896b

Moreover you will need to install the Visual Code IDE. In the latter there is a IBM Blockchain extension that will allow you to promptly get an hyperledger network up and running by deploying the necessary docker images and will allow to interfere with your network through a beginner friendly GUI.

Notice that due to some dependency issues arising with a recent upgrade you should download VS code version 1.39 at the following link.

Should you have issues on Catalina Mac OS to open visual studio follow this instructions.

Once you download it, you can download the IBM Blockchain extension by following the steps in this video:

Install node

brew update
brew install node

Install nvm to handle specific node versions and use the desired version under which this tutorial was developed.

This is necessary as some of the demo available were developed in the past and requires older versions of node. You can easily switch back to your favorite node version once your done with the demo using nvm

## install nvm
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh | bash

=> Appending nvm source string to /Users/marcohassan/.bashrc
=> Appending bash_completion source string to /Users/marcohassan/.bashrc
=> Close and reopen your terminal to start using nvm or run the following to use it now:

## add the necessary nvm configuration to your bash configuration file.
## notice that Mac OSX users might need to switch from ~/.bashrc to ~/.bash_profile
echo "export NVM_DIR='$HOME/.nvm'" >> ~/.bashrc
echo "[ -s '$NVM_DIR/nvm.sh' ] && \. '$NVM_DIR/nvm.sh'  # This loads nvm" >> ~/.bashrc
echo "[ -s '$NVM_DIR/bash_completion' ] && \. '$NVM_DIR/bash_completion'  # This loads nvm bash_completion" >> ~/.bashrc

Check what Node.js versions are installed on your machine

nvm ls

->       v8.9.0 *
         system
default -> v8.9.0 *
node -> stable (-> v8.9.0 *) (default)
stable -> 8.9 (-> v8.9.0 *) (default)
iojs -> N/A (default)
lts/* -> lts/erbium (-> N/A)
lts/argon -> v4.9.1 (-> N/A)
lts/boron -> v6.17.1 (-> N/A)
lts/carbon -> v8.17.0 (-> N/A)
lts/dubnium -> v10.19.0 (-> N/A)
lts/erbium -> v12.16.1 (-> N/A)

If you do not have v8.9.0, install the specific node version for this tutorial.

nvm install v8.9.0

Change your node version to the desired version

nvm use v8.9.0

In the same way you can easily switch back to your favorite Node.js version after this tutorial.

Update your npm to use a specific version.

npm install -g npm@6.0.0

git clone https://github.com/IBM/blockchainbean2.git

cd ./blockchainbean2/
pwd
echo ""
ls

From here on you are ready to go. We expect you on Wednesday for a nice hands-on lab, where we will deploy the permissioned Blockchain Network.
