Hybrid blockchain and pseudonymous authentication for secure and trusted IoT networks

This paper addresses the issue of secure and trusted Internet of Things (IoT) networks by adopting the emerging blockchain technologies. This paper proposes a new hybrid blockchain technology to address the trusted IoT issues such as trustless communications and decentralized applications. Besides, we also present that the pseudonymous authentication technique can use a puzzle-solving computation to enable trustless communications for the IoT and provide the capabilities of near real-time transactions. In our previous work, we presented a decentralized software framework for the IoT by using a p2p network and the concept of the blockchain. In this paper, we outline the core components of the hybrid blockchain and delve deeper the algorithms of the hybrid consensus to provide the capabilities for our hybrid blockchain technology.
