The technological approach 

Now that we have a better understanding of our process and potential problems, let's see how technology can be useful to us. Here's a representation of a standard blockchain Hyperledger Fabric architecture:

The preceding diagram shows us three important layers: frontend applications (on the left), API/SDK (in the center), and Hyperledger Fabric and the IoT platforms (on the right). 

Let's review each layer in more detail.

Frontend applications

This layer is responsible for data input and can be a packet, such as one from SAP, Salesforce, or Siebel, or a custom application. It can also interact with IoT devices, collecting data and registering in the blockchain...
