The Init function

The Init function is called when the chaincode is instantiated by the blockchain network and the function initializes the asset management data. In this function, we need to set up the OrgAsset initialization information. The three parameters we pass to call the Init function are assetId, assetType, and deviceId. This will set our device asset information, then we call the PutState(key, value) method to store the key and the value on the ledger.
