  • Integrating IoT systems with blockchain provides several benefits in providing trust, cost reduction, more scalable and accelerated data exchanges, and security in IoT implementations. One such case is in the logistics and supply chain industry, where IoT-based blockchain applications can be used to facilitate the fast and efficient movements of goods and products. Such industries have challenges such as too much paperwork, lack of control over shipping periods, waste in the case of a supply of perishable goods, and lengthy payment settlement cycles. Blockchain can collect and store data regarding the temperatures, locations, times of departure and arrival, and the status of the containers during shipping. Additionally, the immutable aspect of blockchains can ensure that all participants in the process can access data that they trust.

However, blockchain integration into IoT systems can introduce specific challenges concerning scalability. For example, the overheads where IoT devices have limited bandwidth connections and processing capabilities, complex consensus algorithms, high computational cost, latency, transaction throughput, a substantial amount of data (transactions) generated by IoT devices, privacy, and regulations are a few factors to consider. The major goal of this study is to figure out how scalability issues in IoT-based blockchain applications are addressed.
