With1 the rapid growth of the internet of things (IoT) market and requirement, low power wide area (LPWA) technologies have become popular. In various LPWA technologies, Narrow Band IoT (NB-IoT) and long range (LoRa) are two main leading competitive technologies. Comparing to NB-IoT network that mainly built and managed by mobile network operators, LoRa wide-area network (LoRaWAN) is mainly operated by private companies or organizations, which will bring the trust issues between application customers and network operations. In this paper, we proposed a blockchain technology based solution to build an open, trusted, decentralized and tamper-proof system for LoRaWAN. To the best of our knowledge, this is the first work that integrating blockchain technology and LoRaWAN IoT technology.
