Information sharing is becoming popular for its efficiently processing and modeling in intelligent era. During the information sharing procedure, especially in the Industrial Internet area, some problems should be considered, such as storage centralization, low integration efficiency, data isolation, weak trust, poor security performance, and privacy protection, which are the challenges for forming free circulation. For this purpose, blockchain technology could be used to realize the decentralized storage, distrust and traceability of information. This paper proposes a sharing mechanism of information based on blockchain technology, for the processes of collection, storage and application. It is concluded that building a multi-collaborative information sharing mechanism based on blockchain, can satisfy the requirement of safe and efficient sharing.
