Summary

The architecture described in this chapter involves many components, and the implementation may seem a little complex. By now, we've established that the combination of IoT and blockchain can mitigate several issues and transform the workings of the modern food chain. For example, such an implementation can bring transparency between members, allowing them to control data more efficiently; increase their security; make the process automatic and dynamic; remove middlemen; and make the chain less complex overall.

We also saw that IoT works as the extension of computing and network capabilities for devices and sensors, enabling them to make machine-to-machine interactions with minimal or no human input. These technological components bring advantages such as unprecedented automation, cost reduction for provisioning, energy savings, value-added services, and efficient management.

Blockchain's integration with IoT will make possible data exchange between edge devices such as sensors, barcode...
