Building a supply chain management system for OCOP goods and agricultural products based on Hyperledger Fabric platform

1. Install Hyperledger Fabric 2.5.0

Install Hyperledger Fabric

curl -sSL https://bit.ly/2ysbOFE | bash -s

Grant permission for folder fabric-samples

chown -R <ubuntu-user-name> ./fabric-samples

Change directory to folder fabric-samples

cd fabric-samples

2. Clone needed source to this project

git clone https://github.com/BootcampXVI-Project/SupplychainNetwork.git

git clone https://github.com/BootcampXVI-Project/supplychain_chaincode.git

git clone https://github.com/BootcampXVI-Project/supply_chain_application.git

git clone https://github.com/BootcampXVI-Project/explorer.git

git clone https://github.com/BootcampXVI-Project/supply_chain_client.git

3. Running the Supplychain Network

Change directory to folder Supplychain Network

cd SupplychainNetwork

Run network

./network.sh up createChannel -ca -s couchdb

Deploy chaincode (smart contract)

./network.sh deployCC -ccn basic -ccp ../supplychain_chaincode/go/ -ccl go -cci InitLedger

Export PATH and FABRIC_CFG_PATH

export PATH=${PWD}/../bin:$PATH
export FABRIC_CFG_PATH=$PWD/../config/

Predeclare for authorize

ORDERER_ADDRESS=localhost:7050
ORDERER_TLS_CERT="${PWD}/organizations/ordererOrganizations/supplychain.com/orderers/orderer.supplychain.com/msp/tlscacerts/tlsca.supplychain.com-cert.pem"

SUPPLIER_PEER_ADDRESS=localhost:7051
SUPPLIER_PEER_TLS_CERT="${PWD}/organizations/peerOrganizations/supplier.supplychain.com/peers/peer0.supplier.supplychain.com/tls/ca.crt"

MANUFACTURER_PEER_ADDRESS=localhost:7061
MANUFACTURER_PEER_TLS_CERT="${PWD}/organizations/peerOrganizations/manufacturer.supplychain.com/peers/peer0.manufacturer.supplychain.com/tls/ca.crt"

DISTRIBUTOR_PEER_ADDRESS=localhost:7071
DISTRIBUTOR_PEER_TLS_CERT="${PWD}/organizations/peerOrganizations/distributor.supplychain.com/peers/peer0.distributor.supplychain.com/tls/ca.crt"

RETAILER_PEER_ADDRESS=localhost:7081
RETAILER_PEER_TLS_CERT="${PWD}/organizations/peerOrganizations/retailer.supplychain.com/peers/peer0.retailer.supplychain.com/tls/ca.crt"

CONSUMER_PEER_ADDRESS=localhost:7091
CONSUMER_PEER_TLS_CERT="${PWD}/organizations/peerOrganizations/consumer.supplychain.com/peers/peer0.consumer.supplychain.com/tls/ca.crt"

Define channel and chaincode name

CHANNEL_NAME=supplychain-channel
CHAINCODE_NAME=basic

Set up the environment variables for each organization

source ./scripts/envVar.sh && setGlobals supplier

Init ledger

peer chaincode invoke \
  -o $ORDERER_ADDRESS \
  --ordererTLSHostnameOverride orderer.supplychain.com \
  --tls \
  --cafile $ORDERER_TLS_CERT \
  -C $CHANNEL_NAME \
  -n $CHAINCODE_NAME \
  --peerAddresses $SUPPLIER_PEER_ADDRESS \
  --tlsRootCertFiles $SUPPLIER_PEER_TLS_CERT \
  --peerAddresses $MANUFACTURER_PEER_ADDRESS \
  --tlsRootCertFiles $MANUFACTURER_PEER_TLS_CERT \
  --peerAddresses $DISTRIBUTOR_PEER_ADDRESS \
  --tlsRootCertFiles $DISTRIBUTOR_PEER_TLS_CERT \
  --peerAddresses $RETAILER_PEER_ADDRESS \
  --tlsRootCertFiles $RETAILER_PEER_TLS_CERT \
  --peerAddresses $CONSUMER_PEER_ADDRESS \
  --tlsRootCertFiles $CONSUMER_PEER_TLS_CERT \
  -c '{"function":"InitLedger","Args":[]}'

Generate organization config files

cd organizations

./ccp-generate.sh

4. Running the explorer

Change directory to folder explorer

cd ../../explorer

Copy entire crypto artifact directory (organizations/)

cp -r ../SupplychainNetwork/organizations/ .

start up explore and explorer-db services

docker-compose up -d

5. Running the supply_chain_application

Change directory to folder supply_chain_application

cd ../supply_chain_application

Install npm packages

npm install

Start application

npm start

6. Running the Web Application

Change directory to folder supply_chain_client

cd ../supply_chain_client

Install npm packages

npm install

Build Angular project

ng build

Start application

ng serve
