Hx Blockchain Medical Record

About

Hx is a Blockchain-based medical records and archiving solution built on the permissioned Hyperledger Fabric blockchain framework to ensure security, privacy, provenance and immutability in the medical field. Hx was created as a project for IS4302 Blockchain and distributed ledger technologies and is built on Hyperledger Composer, React and Spring (Java backend).

Installation

Download the vagrant environment from https://github.com/suenchunhui/fabric-tutorial-vagrant. Ensure that ports 3001-3009 are mapped in the vagrantfile, if not, edit the vagrantfile to add the port mappings. Start vagrant with the command "vagrant up" in the directory with the vagrant file.

In the IDE available at "http://localhost:8181" (Username: "root" Password: "secret"), cd to ~/composer-playground and drop the hxblockchain.bna BNA file into the composer-playground folder. Then, use the console to copy the file into the composer-playground/mnt folder with the command "sudo cp hxblockchain.bna mnt"

run "./playground.sh -f docker-compose-deploy.yaml up"

Copy and paste the following commands to create a new admin: docker exec -it ca.org1.example.com fabric-ca-client enroll -M registrar -u http://admin:adminpw@localhost:7054

docker exec -it ca.org1.example.com fabric-ca-client register -M registrar -u http://localhost:7054 --id.name kenneth --id.affiliation org1 --id.attrs '"hf.Registrar.Roles=client"' --id.type user

Enter the CLI container using: docker exec -it cli bash

Using the password for the newly registered admin, deploy the network BNA using: composer network deploy --archiveFile /mnt/hxblockchain.bna -A kenneth -c PeerAdmin@hlfv1 -S

Import the created admin card using: composer card import -f [email protected]

Create a new terminal in the IDE and cd to composer-playground.Start the admin rest server with: ./start_rest_server.sh -i 1 -p 3001 -c kenneth@is4302-hx-network

In the java project, cd to the folder with pom.xml, run the project with "mvn spring-boot:run". Maven is required to run the back-end. When "Application started successfully!"appears, the server has created some static data in the blockchain and is running at http://localhost:9191

In the CLI container, run the following commands to create the identity cards of the users.

• composer identity issue -c kenneth@is4302-hx-network -u PATIENT001 -a org.acme.model.Patient#PATIENT001
• composer card import -f [email protected]
• composer identity issue -c kenneth@is4302-hx-network -u PATIENT002 -a org.acme.model.Patient#PATIENT002
• composer card import -f [email protected]
• composer identity issue -c kenneth@is4302-hx-network -u DOCTOR001 -a org.acme.model.Practitioner#DOCTOR001
• composer card import -f [email protected]
• composer identity issue -c kenneth@is4302-hx-network -u EM001 -a org.acme.model.Employer#EM001
• composer card import -f [email protected]
• composer identity issue -c kenneth@is4302-hx-network -u PHARM001 -a org.acme.model.Pharmacy#PHARM001
• composer card import -f [email protected]
• composer identity issue -c kenneth@is4302-hx-network -u DOCTOR002 -a org.acme.model.Practitioner#DOCTOR002
• composer card import -f [email protected]

In the terminal in composer-playground, run the following commands to start the rest server for each user identity.

• ./start_rest_server.sh -i 2 -p 3002 -c PATIENT001@is4302-hx-network
• ./start_rest_server.sh -i 3 -p 3003 -c PHARM001@is4302-hx-network
• ./start_rest_server.sh -i 4 -p 3004 -c DOCTOR001@is4302-hx-network
• ./start_rest_server.sh -i 6 -p 3006 -c EM001@is4302-hx-network
• ./start_rest_server.sh -i 7 -p 3007 -c PATIENT002@is4302-hx-network
• ./start_rest_server.sh -i 8 -p 3008 -c DOCTOR002@is4302-hx-network

In a new terminal in your host OS, start the front end server by going into the Hx-Blockchain-Frontend folder, then run "npm install" then "npm run build", followed by "npm start".

The HxBlockchain application can be accessed at http://localhost:3010
