Аннотация:Natural and artificial systems and agents overcome communication limitations in different ways. It is necessary to develop scenarios for their interaction (for example, in hybrid environments and Industry 4.0), identifying the most risky strategic lines of mutual danger and discovering areas of transparent communication. In this vein, the problem of communication transparency can be understood as a problem of trust. The article discusses the concept of transparency (security, reliability) of communication in the social and technological spheres. This problem has been studied in the specific contexts of artificial intelligence and blockchain. It has been methodologically shown that the combination of these two technologies can significantly expand the capabilities of both. Artificial intelligence is generating more efficient and secure blockchain protocols as a network, as well as private implementations of blockchain solutions such as smart contracts. The probable ecological optimization of the blockchain by artificial intelligence due to the detection of ineffective algorithmic solutions or used software and hardware resources is also important. In turn, blockchain technology provides artificial intelligence with an environment for unfolding and building a transparent history (logging, precedency, patterns, templates). The network nature of the blockchain contributes, on the one hand, to the globality of solutions, the distribution of information, and, on the other hand, to the locality and privacy of owner interests.
