E-Challan system implemented on blockchain

This project is a POC of implementation of blockchain on an e-challan system.

There are 3 servers to be created :

1. REST server for hyperledger composer
2. MongoDB database
3. Angular 8 server

First clone the whole project on your system. Then, follow these steps :

Installing the business network on hyperledger fabric and creating REST api

Prerequisites:

• Hyperledger fabric is started by running the command in the fabric-dev-servers directory.

export FABRIC_VERSION=hlfv11 && ./startFabric.sh && ./createPeerAdminCard.sh

1. Go to Business Network directory
2. Install the tutorial-network@0.0.7.bna on hyperledger fabric using :

composer network install --card PeerAdmin@hlfv1 --archiveFile tutorial-network@0.0.7.bna && composer network start --networkName tutorial-network --networkVersion 0.0.7 --networkAdmin admin --networkAdminEnrollSecret adminpw --card PeerAdmin@hlfv1 --file networkadmin.card && composer-rest-server -c admin@tutorial-network -n never -u true -w true

This will run a composer REST server on https://localhost:3000/

Creating database server

Prerequisites:

• Install Mongodb.
• Install nodemon using

sudo apt install nodemon

1. Go to api directory
2. Run the following command :

nodemon server

The node server will then run on https://localhost:4000

Serving the angular app

Prerequisites:

• Angular CLI is installed.

In the root directory, use the following command :

ng serve

The angular server will run on https://localhost:4200 Now, you can access your web application on https://localhost:4200.
