Student's Journey (Using Hyperledger Fabric Composer)

The business network of this application defines:

Participant Schools Universities

Asset Students

Transaction Transfer Students from one school to another, or from a school to a university, or from a university to another

In order to test the network on your local machine:

First, install the pre-requisites by executing the commands on this page: https://hyperledger.github.io/composer/latest/installing/installing-prereqs.html

Second, install the development environment by executing the commands on this page: https://hyperledger.github.io/composer/latest/installing/development-tools.html

Third, follow the below steps: 1- Clone or download the Schools-Network repo: https://github.com/RbkCrypto/Schools-Network

2- Navigate in terminal to the repo location on your machine.

3- The network should be packaged into a deployable archive by executing the command below, which will create the bna file in the current folder: composer archive create -t dir -n .

4- Install the business network using this command: composer network install --card PeerAdmin@hlfv1 --archiveFile schools-network@1.0.0.bna Note: schools-network is the name of this app network, you can name it as you prefer.

5- To start the business network run the following command (takes 1 - 3 minutes): composer network start --networkName schools-network --networkVersion 1.0.0 --networkAdmin admin --networkAdminEnrollSecret adminpw --card PeerAdmin@hlfv1 --file networkadmin.card

6- To import the network administrator identity as a usable business network card, run the following command: composer card import --file networkadmin.card

7- To check if the business network has been deployed successfully, run the following command to ping the network: composer network ping --card admin@schools-network

To create the REST API, run the following command:

composer-rest-server

and then answer the questions that will appear as following :

1- Enter admin@schools-network as the card name.

2- Select never use namespaces when asked whether to use namespaces in the generated API.

3- Select No when asked whether to secure the generated API.

4- Select No when asked whether to enable authentication for the REST API using Passport.

5- Select Yes when asked whether to enable event publication over WebSockets.

6- Select No when asked whether to enable TLS security for the REST API.

The Last step: Navigate to school-app which is the client application (Angular4), then run the following command and the network will be ready to be used: npm start This will start the angular application running against your REST API at http://localhost:4200
