A Comparative Assessment of Blockchains in Embedded Systems

With the inclusion of network interfaces always connected to embedded systems, the concept of Internet of Things emerges. Today, IoT devices are in virtually all human activities facilitating the quality of life of people. Despite the advantages of these devices, there are also some drawbacks, one of the main ones being cyber security. One of the technologies currently in vogue to mitigate cyber security problems is blockchain. The overall blockchain approach is to be implemented on the server side, where computing capabilities are not as limited as in embedded systems. This paper proposes a methodology to assess the blockchain technologies. To evaluate the proposed methodology a comparative study of various blockchain technologies that can be implemented in embedded systems particularly for use in smart meters with SBC Raspberry Pi has been conducted. The results show that lightweight implementations of Blockchains are better for embedded systems.
