Abstract: The present invention addresses the issue of secure and trusted Internet of Things (IoT) blockchain networks by adopting the emerging blockchain technologies. The present invention proposes a new hybrid blockchain technology to address the trusted IoT issues such as trustless communications and decentralized applications. Besides, the present invention also disclose 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.
