In this supply chain network there will be 3 participating organizations:

• Farmers (Org1) (2 nodes)
• Retailers (Org2) (2 nodes)
• Supermarket-Consumers (Org3) (1 node)

(Insert Network Architecture Image)

To avoid conflicts we create 2 private collections between transacting parties (Org1-Org2, Org2-Org3). Any transactions details (prices etc) should remain private and only transacting organizations should have access.

1. Bring up the network, create credentials and certificates using Fabric CAs and create the network channel.

./network.sh up createChannel -ca

(End result image)

2. Deploy smart contract with private collection configuration

./network.sh deployCC -ccn try -ccp ../@5Scenario/ -ccl go -ccep "OR('Org1MSP.peer','Org2MSP.peer','Org3MSP.peer')" -cccg ../@5Scenario/collections_config.json

(result image)

3. Deploy Front-end and Backend Go on ImprovedUi/WebUi/backend folder.

cd ../ImprovedUi/WebUi/

On separate terminals run while on backend folder: To run backend:

cd backend/
npm run server

To run front-end:

npm run client

Alternatively use ./start.sh script to automatically start the whole application. NOTE: My terminal is Tilix so you should modify the script commands on ImprovedUi/WebUi/backend/package.json. On the dev command in the package.json change Tilix to your local terminal.

  "scripts": {
    "server": "nodemon index.js",
    "client": "npm run start --prefix ../frontend",
    "dev": "concurrently --kill-others-on-fail \"npm run server\" \"tilix -a session-add-down -x npm run client\""
  }
