Application of Ship Data Based on Blockchain

Aiming at the need for controlled sharing and application of data during ship design and research, a method based on blockchain is proposed in this paper. Blockchain is introduced in this method for data encryption and storage, as well as property authentication and usage log. Data-driven program is used for data application, making data invisible while accessible for users. A ship resistance prediction program based on dynamic surrogate model with relevant data is used as demonstration and successfully implemented the intended functions, showing this method available for practical application.
