INTUZ is presenting a working demo for Property blockchain based on Hyperledger Fabric framework.
- The demo is based on Hyperledger Fabric framework created to keep the record for the transaction of the Property owners.
- The chaincode includes the following fields e.g.: Owner name, House number, Address field 1, Address field 2, City, Pincode, Area (in Sq. feet), Purchase Date, Purchase Type, Price.
- A user can add and edit the information like property owner, Date of Purchase etc.
Please follow the below steps, this will execute the results in terminal.
Copy the chaincode property.go in fabric-samples/chaincode/chaincode_example02/go directory.
Go to docker dev mode, open the bash and fire the following command. This will create a docker container and put the container up for the execution.
docker-compose -f docker-compose-simple.yaml up -d
To go into Docker chaincode.
docker exec -it chaincode bash
To build the executable from a chaincode.go file. P.S.: Please don't execute this command If the executable file is already available at the desired path.
go build -o property
To set the Peer address port.
CORE_PEER_ADDRESS=peer:7052 CORE_CHAINCODE_ID_NAME=mycc:0 ./chaincode_example02/go/property
To go into Docker CLI
docker exec -it cli bash
This will install the chaincode.
peer chaincode install -p chaincodedev/chaincode/chaincode_example02/go -n mycc -v 0
To instantiate the chaincode.
peer chaincode instantiate -n mycc -v 0 -c '{"Args":["init"]}' -C myc
To insert multiple Property data into Blockchain, kindly follow the below commands but make sure to change the text instead "pay12" to the actual data in below format.
peer chaincode invoke -n mycc -c '{"Args":["addData","1","OwnerName","houseNo","addressField1","addressField2","city","pincode","area","purchaseDate","purchaseType","pay12"]}' -C myc
peer chaincode invoke -n mycc -c '{"Args":["addData","2","pay12","pay12","pay12","pay12","pay12","pay12","pay12","pay12","pay12","pay12"]}' -C myc
peer chaincode invoke -n mycc -c '{"Args":["addData","3","pay12","pay12","pay12","pay12","pay12","pay12","pay12","pay12","pay12","pay12"]}' -C myc
peer chaincode invoke -n mycc -c '{"Args":["addData","4","pay12","pay12","pay12","pay12","pay12","pay12","pay12","pay12","pay12","pay12"]}' -C myc
peer chaincode invoke -n mycc -c '{"Args":["addData","5","pay12","pay12","pay12","pay12","pay12","pay12","pay12","pay12","pay12","pay12"]}' -C myc
peer chaincode invoke -n mycc -c '{"Args":["addData","6","pay12","pay12","pay12","pay12","pay12","pay12","pay12","pay12","pay12","pay12"]}' -C myc
peer chaincode invoke -n mycc -c '{"Args":["addData","7","pay12","pay12","pay12","pay12","pay12","pay12","pay12","pay12","pay12","pay12"]}' -C myc
To check whether the data is inserted successfully or not.
peer chaincode query -C myc -n mycc -c '{"Args":["readAllData"]}'
To fetch the data for single record using ID
peer chaincode query -C myc -n mycc -c '{"Args":["readData","1"]}'
To update data in the chaincode
peer chaincode invoke -C myc -n mycc -c '{"Args":["UpdateData","2","abc"]}'
To delete any specific chaincode data
peer chaincode invoke -C myc -n mycc -c '{"Args":["deleteData","1"]}'
