Necessity of X(Cross)-Blockchain System for Near Future Artificial Brain Society

In recent years, advances in science and technology have been remarkable. While advances in science and technology have made the world more convenient, there are also problems associated with it. In the near future, people will need to simultaneously control themselves, their cyberspace selves, and the robots and androids belonging to person. Additionally, as medicine progresses, genetic manipulation and the evolution of organoids make it difficult to guarantee individual species. Additionally, as AI technology advances, the threat of AI dominating society also emerges. Furthermore, artificial brains will appear, and the era of brain-to-brain communication will appear. In such background, information management becomes extremely difficult. Data management using blockchain is optimal from the viewpoint of data robustness, block management, and distributed management. Data management using blockchain is optimal from the viewpoint of data robustness, block management, and distributed management. However, traditional blockchain can only manage one-dimensional data information. To solve this problem, it is necessary to add some accompanying information to the data itself, such as the validity of the master-slave relationship. We have devised an algorithm for X (cross) blockchain, which composes several blockchains and shares their information.
