Initializing the chaincode

Next, we'll implement the Init function. Init() allows the chaincode to initialize the insuree data to start the claim request. In our case, we will set up and register the insuree person information, as follows:

func (c *ClaimContract) Init(stub shim.ChaincodeStubInterface) pb.Response {         args := stub.GetStringArgs()         if len(args) != 5 {                 return shim.Error("Incorrect arguments. Expecting a key and a value")         }         insureeId := args[0]         firstName := args[1]         lastName := args[2]         ssn := args[3]         policyNumber := args[4]         insureeData := Insuree{                 Id:           insureeId,                 FirstName:    firstName,                 LastName:     lastName,                 SSN:          ssn,                 PolicyNumber: policyNumber}         insureeBytes, _ := json.Marshal(insureeData) err := stub.PutState(insureeId, insureeBytes) ...
