Tendermit implementation of hyperledger fabric fabcar chaincode

Tendermit implementation of hyperledger fabric fabcar chaincode: https://github.com/hyperledger/fabric-samples/tree/release/chaincode/fabcar

The state data is persistently stored in a LevelDb database.

Implemented Operations: createCar, queryAllCars, changeCarOwner

Transactions

To test:
tx is json base64 encode, the response value in the result is also json base64 encoded

Can use https://www.base64decode.net/ to encode/decode

1. CreateCar car1

decoded tx value:
{"operation": "createCar", "data": {"ID": "car1", "Make": "Peugeot", "Model": "205", "Colour": "red", "Owner": "Jane"}
