SupplyChain - HLF project :

Objective :

In the traditional supply chain models, the information about an entity is not fully transparent to others, which leads to inaccurate reports and a lack of interoperability. Emails and printed documents provide certain information, but still can’t contain fully detailed visibility and traceability information since the products across the entire supply chain are hard to trace. It is almost impossible for the consumer to know the true value of the product they purchased. Since the blockchain is a transparent, immutable, and secure decentralized system, it is considered to be a game-changing solution for traditional supply chain industries. It can help to build an effective supply chain system by improving the following areas:

      * Tracking the products in the entire chain
      * Verifying and authenticating the products in the chain
      * Sharing the entire chain information between supply chain actors 
      * Providing better auditability

Use case :

Farm to fork tracking
Diamond tracking
High priced goods such as Leather goods , watches , dresses etc.

Components Developed :

Frontend app with React.js
Middleware APIs using Node
Node.js for SDK
Network - Hyperledger Fabric
Chaincode - GoLang

Users in this Application :

Manufacture
WholeSeller
Distributor
Retailer
Consumer

Application Architecture :

Application Flow :

Users are enrolled into the application by an Admin.
New Products will be created by the Manufacturer only.
Then Product will be sent to WholeSeller
Wholesalers will send the product to the Distributor.
Distributor will send it to Retailer
Consumer could place the order
Consumer will mark as Delivered once the product is delivered

Fabric Network details :

Three Orgs (Manufacturer/MiddleMen/Consumer)
Five peers
One Orderer (Org1)
One Channel
Three Certificate Authority (Each org 1 CA)
Fabric network implemented with Fabric CA as certificate authority.

Chaincode Functions :

createUser (Admin)
signIn (user Login)
createProduct: ( Manufacturer)
updateProduct (Manufacturer,Wholesaler,Distributor,Retailer)
sendToWholesaler
sendToDistributor
sendToRetailer
sellToConsumer
QueryAsset (Query by Product ID)
QueryAll (All )
orderProduct(Consumer places order , productID -> Retailer)
deliveredProduct (Retailer Updates)
Init - Initialize Counters to NIL
Invoke - To invoke each function in the chaincode

Planned APIs :

User SignIn
createProduct
sendToWholesealer
sendToDistributor
sendToRetailer
sellToCustomer
Update product
Email Notification service for above APIs

Steps to up the network using shell scripts :

sudo docker ps --all
./stopNetwork.sh
./teardown.sh
./operate.sh up

Steps to run the API server

cd web-app/servers/

npm install

nodemon app.js

Steps to up the network using commands :

1. generate certificates

../bin/cryptogen generate --config=./artifacts/crypto-config.yaml --output=./artifacts/network/crypto-config

2. export

export FABRIC_CFG_PATH=${PWD}/artifacts

3. generate the genesis block

../bin/configtxgen -profile TraceOrdererGenesis -outputBlock ./artifacts/network/genesis.block

4. export channel name

export CHANNEL_NAME=supplychainchannel

5. generate the channel transaction file

../bin/configtxgen -profile TraceOrgsChannel -outputCreateChannelTx ./artifacts/network/channel.tx -channelID $CHANNEL_NAME

6. update anchor peers

../bin/configtxgen -profile TraceOrgsChannel -outputAnchorPeersUpdate ./artifacts/network/ManufacturerMSPanchors.tx -channelID $CHANNEL_NAME -asOrg ManufacturerMSP

../bin/configtxgen -profile TraceOrgsChannel -outputAnchorPeersUpdate ./artifacts/network/MiddleMenMSPanchors.tx -channelID $CHANNEL_NAME -asOrg MiddleMenMSP

../bin/configtxgen -profile TraceOrgsChannel -outputAnchorPeersUpdate ./artifacts/network/ConsumerMSPanchors.tx -channelID $CHANNEL_NAME -asOrg ConsumerMSP

7. up the network

export MANUFACTURER_CA_PRIVATE_KEY=$(cd ./artifacts/network/crypto-config/peerOrganizations/manufacturer.example.com/ca && ls *_sk)

export MIDDLEMEN_CA_PRIVATE_KEY=$(cd ./artifacts/network/crypto-config/peerOrganizations/middlemen.example.com/ca && ls *_sk)

export CONSUMER_CA_PRIVATE_KEY=$(cd ./artifacts/network/crypto-config/peerOrganizations/consumer.example.com/ca && ls *_sk)

docker-compose -f artifacts/docker-compose.yaml up -d

8. get into CLI

docker exec -it cli bash

9. export channel name

export CHANNEL_NAME=supplychainchannel

10. create channel

peer channel create -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/channel.tx --tls $CORE_PEER_TLS_ENABLED --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

11. peer 0 manufacturer join channel

peer channel join -b supplychainchannel.block

12. peer 0 middlemen join channel

peer 1 middlemen join channel

peer 2 middlemen join channel

peer 0 consumer join channel

13. update anchor peers

peer 0 manufacturer
