Learn how to use a an IoT Asset Tracking device, build a blockchain network, and configure a Node-RED dashboard to monitor a perishable network supply chain. You can also use a simulated tracker if you don’t want to purchase and set up the hardware.
When multiple participants, such as farms, manufacturers, processing plants, trucks, ports, ships, distribution centers, and consumer retail outlets, are involved in the safe shipment and payment of cargo, you can use a blockchain network to record immutable transactions as the cargo shipment progresses through its delivery journey. In this course, you’ll do the following main tasks: – Configure an asset tracker IoT device (or use the simulator) – Build a blockchain business network in Hyperledger Composer – Build an IoT application to visualize and analyze the data from the asset tracker: — Create an IoT starter app in IBM Cloud — Create Node-RED flows to control and receive events from Particle.io, write events to the blockchain network, and load blockchain transaction history — Use Node-RED to build an asset tracking dashboard
Lab 1: Build a blockchain network
Question: The default blockchain Perishable Goods Network in Hyperledger Composer includes which participants? Select all that apply.
Question: Which of these file types is used for a model file?
Question: To capture conditions for a crash, a hard jolt, or other incidents based on the accelerometer data, what field did you add to the Contract asset?
Question: What is the purpose of this event: TemperatureThresholdEvent()?

Understand the imported Node-RED flows
Question: Which task is not done by the Start Particle Electron flow?
Question: Which flow takes the arriving data, reformats it, and calls the next flow to write the Particle Electron events to the transaction history of the blockchain network?
Question: Which flow sets up a series of GET and POST commands?
Question: The Track Asset History flow filters the array to the selected device and time frame.
Question: What is one task that is done by the Load Blockchain flow?
Question: What is the purpose of exposing the blockchain network as a REST API?
Question: What is included in the Internet of Things Platform Starter? Select all that apply.
Question: What is the purpose of the ParticleSSE node in the Particle Receiver flow?
Question: What is the main task of this flow?
Question: Hyperledger Composer REST APIs cannot be used by Node-RED to communicate to the blockchain perishable network.
Question: What must you add to the model file for the IoT data to be associated with the asset and shipment?
Question: When you export the code for your network from Hyperledger Composer, what type of file is created?
Question: You use the Google Maps Locator API to triangulate the geographical location of a device.

Question: The Particle Electron program is written in which language?
