The project website is here.
The project is curretly in development using frameworks and tools from Hyperledger, in particular Fabric and Composer
In a previous posting we focussed on deploying version 1 of the business network bforos onto a a multi-organization Hyperledger Fabric.
In this posting we will be deploying into a single-organization the same business network, start the rest-server and the user interfaces generated with Angular CLI version 1.0.1. With the user interfaces we will be able to create research objects and participants, these participants will be able to claim authorship on these objects. In addition we will be able to track the history of the research objects.
Follow steps one and two from the tutorial: 1-Starting a Hyperledger Fabric network; 2-Exploring the Hyperledger Fabric network.
In step three create a folder called certificates and follow the instructions:
3-Building a connection profile (copy the example connection profile) and save to the folder connection.json.
Follow step four to locate the certificate and private key for the Hyperledger Fabric administrator and copying these certificates in the file certificates. Note that these certificates change every time we boostrap the fabric network.
Navigate to the folder you just created and follow step five, creating a business network card for the Hyperledger Fabric administrator:
composer card create -p connection.json -u PeerAdmin -c Admin@org1.example.com-cert.pem -k 114aab0e76bf0c78308f89efc4b8c9423e31568da0c340ca187a9b17aa9a4457_sk -r PeerAdmin -r ChannelAdmin
Follow step six to import the business network card for the Hyperledger Fabric administrator,
composer card import -f PeerAdmin@fabric-network.card
In step seven we install the Hyperledger Composer business network onto the Hyperledger Fabric peer nodes. The business network bforos is defined in bna file, bforos@0.0.6.bna and its located in the repository. A forlder with the specific business network model files, scripts and queries that are packaged in the bna file (using composer archive create) is located in the Blockchain4openscience hyperledger repository.
composer network install -c PeerAdmin@fabric-network -a bforos@0.0.6.bna
In step eight we start the blockchain business network
composer network start --networkName bforos --networkVersion 0.0.6 -A admin -S adminpw -c PeerAdmin@fabric-network
In step nine we import the business network card for the business network administrator
composer card import -f admin@bforos.card
In step ten we test the connection to the blockchain business network
composer network ping -c admin@bforos
To create the REST API run the following command:
composer-rest-server
use admin@bforos as the card name and select: never use namespaces; not to secure the generated API; yes to enable event publication; no to enable TLS security.
In order to build the user interfaces for this busness network please clone the repository and follow the instructions
git clone https://github.com/Blockchain4openscience/bforos-frontend
Now navigate to the folder. Check that npm is installed by running
npm -v
otherwise run. Although npm might already be installed, re-intalling npm is important to update any dependencies.
npm install
Once the installation is complete run,
npm start
and navigate to http://localhost:4200/. The app will automatically reload if you change any of the source files.
Run ng generate component component-name to generate a new component. You can also use ng generate directive|pipe|service|class|module.
Run ng build to build the project. The build artifacts will be stored in the dist/ directory. Use the -prod flag for a production build.
Run npm test to execute the unit tests via Karma.
Run npm run e2e to execute the end-to-end tests via Protractor.
Before running the tests make sure you are serving the app via npm start.
To get more help on the Angular CLI use ng help or go check out the Angular CLI README.
