Research on the blockchain-based trusted ownership confirmation and value transfer system and its light weight of industrial data assets

The development of industrial Internet has greatly improved the digital and intelligent level of industrial enterprises. Industrial data assets have become an increasingly important strategic resource and new production factor. How to ensure the security and credibility of industrial data in the whole life cycle from creation, authorization, sharing and income distribution is the primary problem to be solved at present. To this end, based on the design goal of the industrial data asset value transfer system, a blockchain-based framework for trusted ownership confirmation and value transfer of data assets was proposed, a general framework and specific solution with strong applicability and scalability were constructed, and specific solutions and processes were provided to ensure the trustworthiness and controllability of industrial data assets throughout the entire process of ownership confirmation, access, and revenue sharing in an industrial scenario where data was involved from multiple parties and shared multiple times. To solve the contradiction between security and efficiency, a lightweight trusted blockchain model was proposed, which measured the trustworthiness of nodes based on their behavior and status, and provided a dynamic initial value calculation method for nodes and an overall trust value measurement model for trust management. The consensus protocol algorithm of the blockchain system was optimized based on the trustworthiness of nodes, reducing the probability of malicious attacks on nodes while improving the efficiency of system transaction consensus, achieving security and lightweight parallelism of the entire system. Finally, the superiority of this scheme was verified through simulation experiments.
