governance model to build trust between participants on a shared network.

The creation of a smart contract and its deployment on the blockchain will be

learnt here.

You should complete the installation of Hyperledger Fabric on AWS as also

the installation of Hyperledger Fabric with samples and binaries on the AWS

EC2 instance to run this application.

Blockchain application development

For developing your application, follow these steps:

1. Set up the development environment:

$ cd ~

cd fabric-samples/first-network

sudo docker ps

sudo ./byfn.sh down

sudo docker rm -f $(sudo docker ps -aq)

sudo docker network prune

cd ../wagon && ls

Packaged into one startF abric.sh file, there are a few node.js files

present in the wagon folder, such as enrollAdmin.js, invoke.js,

q uery.js, registerUser.js, and package.json.

2. Fabric client installation:

sudo npm install -g npm@5.3.0

sudo npm update

Notice that the Fabric client 1.3 .0 and Fabric CA client 1.3 0 packages are

installed.

3 . Execute the following command to launch the network:

sudo ./startFabric.sh node

4. Open a new terminal to stream the Docker logs:

$ sudo docker logs -f ca.example.com

This opens the Docker file.

U se node.js script to run, query, and update the records on the Fabric

network.
