Now one of the problems in the development of artificial intelligence is associated with the complexity of searching and access to disparate databases necessary for creating models. Data with the spread of the Internet and the development of computing power has really become very much, but here it is very difficult to find the necessary information. Some databases are located in different "corners" of the Internet in the public domain, others are stored by the companies that gathered them, and to get access to them, you need to pay. In this case, the researcher does not have information about which databases exist, where to look for them and how to access them. The creation of a single database registry for AI would help solve this problem and further stimulate the development of AI. The technology of blocking will allow creating such a single decentralized register. Companies, users and researchers from around the world will be able to download their data there and regulate access to them - the registry will also provide publicly available free databases and databases of individual companies, access to which can be obtained for a fee. At the same time, anyone who adds their database to the register will be able to claim the intellectual property right, which will be confirmed by the blockbuster. On the basis of this right, it will be possible to determine who else has access to the model - all those who wish for free or, for example, for a fee, who will go directly to the database creator, bypassing the numerous intermediaries.
