Hyperledger Fabric - Building Our First Network

Hyperledger Fabric - Building Our First Network

## In your Ubuntu terminal, enter the following commands: -

sudo apt-get install curl
sudo apt-get install golang-go
export GOPATH=$HOME/go
export PATH=$PATH:$GOPATH/bin
sudo apt-get install nodejs
sudo apt-get install npm
sudo apt-get install python
sudo apt-get install docker
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
sudo apt-get update
apt-cache policy docker-ce
sudo apt-get install -y docker-ce
sudo apt-get install docker-compose
sudo apt-get upgrade

## With that, our environment is set up.Next, we're going to download the samples of Fabric that have already been prepared to 
# test it out. Enter the following two commands in your terminal -

sudo curl -sSL https://goo.gl/6wtTN5 | sudo bash -s 1.1.0
sudo chmod 777 -R fabric-samples

##  So now we have the samples.We're going to make sure that everything runs by running our first network. Change into the 
# first-network directory and run the generate script that will create the certificates and keys for the entities that are going to
# exist on our blockchain. This will also create the genesis block (the first block on the blockchain), among other things. 

cd fabric-samples/first-network
sudo ./byfn.sh generate

##   Now bring the blockchain network up with the following command. 

sudo ./byfn.sh up

##  If everything worked, then you successfully created your first Fabric network! Congratulations. Let's bring it down for now. 

sudo ./byfn.sh down


## Okay, so we know our computer can successfully use and deploy Hyperledger Fabric blockchain networks, but what now?
