“…Bitcoin is a chain of immutable blocks (Figure 1), the integrity of which is confirmed by the Proof-of-Work consensus protocol. To add a new block to the network, it is necessary to perform some "work," during which the block information is confirmed [19]. This protocol provides sufficient network security, but the structure in the form of series-connected blocks and the use of an expensive protocol for finding consensus do not allow unlimited scaling.…”

“…When sending information, a network participant randomly selects another participant to whom it transfers all the information it has accumulated in the form of a hash (Already encrypted data is transmitted, which contributes to confidentiality). This algorithm is repeated several times, resulting in a tree that has the general direction, which named Hashgraph [19]. The rate of dissemination increases exponentially until a consensus is reached.…”

“…In 2017, TraceChain technology was developed. The technology is based on AI, which determines the structure of the network, and distributes nodes to ensure maximum speed [19]. Checking the correctness of transactions is extremely fast, as it is performed immediately on all devices at the same time.…”

This article is devoted to an actual research problem in conditions of increased uncertainty and the need for a theoretical rethinking of the tourism phenomenon in the society, when geopolitical upheavals and a decrease in international security are taking place, as well as the pandemic COVID-19, which currently poses new challenges for the tourism industry. Today, it is more relevant and appropriate than ever to think about them from the perspective of blockchain technology, using a fundamental approach to the digitalization of decentralized management of the life cycle of an internal regional tourism product. It is required to develop an integrated scientific and methodological approach to modeling and designing cyber-physical systems for monitoring and managing tourism products, objects, and processes based on blockchain technologies in order to maximize the contribution of the tourism industry to the socioeconomic development of regions.
