ABSTRACT
Programmable logic controllers, or PLCs for short, is ubiquitous in the
field of industrial automation. These devices are used to control and monitor
a variety of processes related to production, ensuring that everything
runs smoothly and efficiently. Unfortunately, there are currently no reliable
means of verifying the accuracy and reliability of these devices, which
can lead to serious consequences in the event of an error or malfunction.
To address this issue, researchers are exploring the use of advanced technologies
such as blockchain to provide greater transparency and security PLC operations.
