Abstract: The Internet of Things (IoT) is the current revolutionary paradigm of connectivity and driving force
behind the state of art applications. However, the exponential growth of the number of IoT devices has increased
the number of security and privacy concerns ranging from the risks of unauthorized data alterations to
the potential discrimination enabled by data analytics over sensitive information. Hence to address these issues,
an IoT platform based on blockchain technology is proposed. Built upon the tamper-proof architecture, the
platform ensures the authenticity and integrity of data. Moreover, a novel approach called Block Analytics Tool
(BAT) is introduced which enables the data analysis applications to be developed using the data stored in the
platform. A pharmaceutical supply chain is used as the use case scenario to show the functionality of the platform.
Furthermore, a model to forecast the demand for pharmaceutical drugs is investigated using a real-world
data set to demonstrate the functionality of the BAT. Finally, the performance of the platform integrated with the
BAT is evaluated.
