Energy-Blocks-App

Frequency based electricity billing on Hyperledger Fabric v1.4 This repo contains the demo of energy billing system based on frequency and using smart-grid.

Prerequisites

Quick Start

  • Clone this repo:
git clone --recursive https://github.com/MD-AZMAL/Energy-Blocks-App.git
  • Install dependencies
npm install
  • Install dependencies for frontend
cd frontend && npm install
  • Run network
./run.sh

Server should be should be available on PORT=4000.

  • To Enroll In Organizations, open new terminal and run
./testAPI.sh

Note: If instantiating chaincode fails, then manually instantiate using curl(Check the instantiation part from testAPI.sh).

Above command should create a config.js in frontend/src/ with correct tokens. If this fails to generate then manually copy-paste the token to respective Organizations.

  • Run Frontend part to interact with API.
cd frontend
npm start

Open browser and access client from localhost:3000.

To Stop and clean the network,

$ docker kill $(docker ps -q) 
$ docker rm $(docker ps -aq) # WARNING: this will remove all your containers.

For Blockchain-Explorer

  • Follow the step 2 and 3 of this blog.
  • Modify the config file in blockchain-explorer/app/platform/fabric and change first-network to balance-transfer.
  • Copy the balance-transfer-bk.json to blockchain-explorer/app/platform/fabric/connection-profile/.
  • Add these lines in start.sh in blockchain-explorer.
FABRIC_PATH=<path> # path to this repo.

ADMIN_KEY=$(ls $FABRIC_PATH/artifacts/channel/crypto-config/peerOrganizations/org1.example.com/users/[email protected]/msp/keystore)

cp ./app/platform/fabric/connection-profile/balance-transfer-bk.json ./app/platform/fabric/connection-profile/balance-transfer.json

sed -i "s/<path>/${FABRIC_PATH}/g" ./app/platform/fabric/connection-profile/balance-transfer.json
# <path> to this repo e.g. /home/user/Energy-Blocks-App, then <path> = \/home\/user\/Energy-Blocks-App
sed -i "s/ADMIN_KEY/${ADMIN_KEY}/g" ./app/platform/fabric/connection-profile/balance-transfer.json
  • Now follow step 6 and 7 from the above blog. Explorer should be running on localhost:8080.
