The service architecture of Internet of things terminal connection based on blockchain technology

This work aims to explore the security convenience of Internet of things (IoT) terminals based on blockchain technology and to enrich the content of IoT terminal applications. The service architecture platform of blockchain technology is proposed for the terminal connection of IoT. First, the characteristics, performance, and fault tolerance of the consensus algorithm are introduced. Then, the construction of blockchain platform is introduced, and the blockchain system and the storage of blockchain data are designed. Next, the consensus algorithm is optimized with the proof of stake equity proof consensus and the improved consensus mechanism of the practical byzantine fault tolerance consensus, to establish a blockchain service architecture platform. Finally, the node connection service architecture and block process are verified and analyzed. The results show that the blockchain-based IoT service architecture constructed under consensus algorithm has high accuracy and safety. The achievements of this study can promote the development of blockchain technology and IoT and play a good role in promoting the combination of blockchain technology and IoT terminal.
