摘要：

In response to the challenges faced by edge computing in terms of storage and security, we design a lightweight and secure edge computing architecture based on blockchain. First, we conducted in-depth research on lightweight communication protocols, and propose a lightweight communication model by combining Constrained Application Protocol (CoAP) and Message Queuing Telemetry Transport (MQTT). Second, in order to ensure the security and traceability of the data on edge computing node, we propose a novel data storage mechanism based on blockchain and InterPlanetary File System (IPFS). Finally, we design an improved scheme of the Practical Byzantine Fault Tolerance (PBFT) consensus algorithm to improve the throughput of the system. The results show that the proposed edge computing architecture has the characteristics of strong robustness and low system overhead, which provides new ideas for promoting blockchain-based edge computing to become a key technology for upgrading Internet of Things (IoT) services.
