The Blockchain-based Internet of Things (BIoT) systems are widely used in diverse industrial fields including agriculture, healthcare, sports business, and so on. However, since the Internet of Things (IoT) devices composing the BIoT systems typically have limited computation and communication resources, the IoT systems are likely to be exposed to various security threats. Lightweight blockchain can provide increased security, privacy, scalability and performance to the IoT systems. However, blockchain itself still has lots of security threats and vulnerability issues depending on its applications. Therefore, in-depth investigation of the security and potential vulnerability of blockchain is important to the secure BIoT systems. In this paper, we explore the security threats of the four layers of the BIoT systems, which is physical layer, network layer, blockchain layer and application layer. We then discuss its implication and future work in the BIoT security literature.
