Blockchain technology has been increasingly used for decentralizing cloud-based Internet of Things (IoT) architectures to address some limitations faced by centralized systems. While many existing efforts are successful in leveraging blockchain for decentralization with multiple servers (full nodes) to handle faulty nodes, an important issue has arisen that external clients (also called lightweight clients) have to rely on a relay node to communicate with the full nodes in the blockchain. Compromization of such relay nodes may result in a security breach and even a blockage of IoT sensors from the network. We propose censorship resistant decentralized IoT management systems, which include a “diffusion” function to deliver all messages from sensors to all full nodes and an augmented consensus protocol to check data loss, replicate processing outcome, and facilitate opportunistic outcome delivery. We also leverage the cryptographic tool of aggregate signature to reduce the complexity of communication and signature verification.
