The Internet of things (IoT) architecture based on the traditional Internet is facing data privacy security issues,central server single point issues,and etc.Building a data security ecosystem is a challenge for the future development of the IoT.The decentralized autonomy,tamper-resistance and security of the blockchain technology are proposing a new solution to this challenge.An IoT architecture was proposed based on the blockchain technology as the foundation of a trust-free network,which provided an information-secure network service for the current IoT.Based on the decentralized characteristics of the blockchain technology,the proposed architecture could replace the client-server (C-S) centralized communication model of the traditional IoT to solve the overload problem of the central server and the data security issues.

Key words: Internet of things, blockchain, smart contract, information security
