Blockchain Technology Based on Algorand Applied to Low-Power and Low-Cost IoT Devices

Thanks to the ever-increasing number of connected, innovative and smart objects that have been adopted since now in almost every sector, the Internet of Things is transforming people lives. Nonetheless, one of the major challenges encountered by practitioners and experts every day is related to cybersecurity and the need of protecting collected information at all the levels of IoT ecosystems. Unfortunately, also due to the growing number of connected devices, data security has become extremely complex. One of the revolutionary technologies that has the potential to address such needs and, also, support privacy and scalability is the Blockchain. Among the various existing Blockchains present in literature and in the market, Algorand is emerging as one of the most promising technologies for the IoT due to its intrinsic self-sustaining and decentralized nature. This paper discusses preliminary results obtained in the adoption of the Algorand Blockchain in two of the most spread low-powered IoT devices such as the Raspberry Pi 4 Model B and the STMicroelectronics STM32MP157A-DK1.
