Remote monitoring and tracking systems, which have become widespread in many areas, are frequently used in areas such as smart home features, health, environment security, monitoring of ambient values, vehicle tracking, etc. The widespread use of this usage has brought security vulnerabilities that need to be worked on. The emerging blockchain technology brings very powerful solutions in this regard. In this study, a system where a server room can be remotely monitored is studied. The values to be monitored are parameters such as temperature, pressure, humidity, flood, fire, network control of different parts of the server room. A new purpose-specific electronic circuit board was designed to read the data collected from the environment. The values read by the board are sent to the server side. The records are kept in the blockchain structure prepared here. The performance metrics of the prepared blockchain structure are measured and the overall performance of the system is discussed.

INTRODUCTION IoT (Internet of Things) technology is a network and communication infrastructure that enables objects (objects) to exchange data by connecting with each other and the internet. This technology enables various objects (sensors, devices, equipment, vehicles, etc.) to share information and interact by connecting to the internet [1]. IoT technology is of great importance for remote monitoring and tracking systems. IoT technology is used in data collection and data analysis processes in terms of remote monitoring and tracking systems. IoT technology makes it possible to collect environmental data (temperature, humidity, pressure, etc.) and other user or event data (location, movement, vibration, etc.) through sensors. This data is sent to remote monitoring and tracking systems and analysed and converted into meaningful information. In this way, information about the status of objects or the development of events can be obtained in real time. In addition, it is critical in remote control and management mechanisms [2]. For example, operations such as switching a device on and off, changing its settings or controlling alarm systems can be performed remotely. This facilitates the management of a remotely accessed system and increases operational efficiency. It provides convenience in monitoring the instantaneous situations occurring in the developed system and configuring warning systems. For example, an automatic alarm can be issued when a security camera detects movement or when a sensor exceeds a certain temperature threshold. In this way, rapid intervention is possible and important situations are immediately recognised. IoT is very useful in ensuring efficiency and cost savings. IoT-based remote monitoring and tracking systems provide efficiency in business processes and reduce costs. For example, production equipment of an industrial plant can be remotely monitored to detect malfunctions in advance and optimise maintenance scheduling. This reduces unexpected downtime, increases productivity and lowers operating costs. With features such as real-time data exchange, remote control, alarm notifications and data analyses via the Internet of Things, these systems meet security, monitoring and management needs in many areas [3]. Remote monitoring systems are technological systems that enable remote monitoring of a place or event. Typically, these systems have elements like cameras, sensors, and communication technologies. Systems for remote monitoring have a wide range of applications and can be utilized in many different contexts. One of the most popular applications used for security purposes is remote monitoring. Using cameras and motion detectors, one may keep an eye on the building's or location's security. These devices can be utilized to find theft, an assault, or other
