The article examines the potential of using blockchain technologies to increase the transparency of business processes and ensure the reliability of accounting information at agricultural enterprises of the Volgograd region. Main problems of accounting and analytical support for regional producers are identified. A conceptual model for integrating distributed ledgers into the internal control and accounting system of agricultural enterprises is proposed. Practical recommendations have been developed for adapting blockchain technologies to the specifics of agricultural production in the Volgograd region, taking into account regional industry characteristics.

This article examines the architecture of a secure information system built on distributed ledger technology. It substantiates the need to transition from a centralized data storage model to a distributed trusted environment that ensures cryptographic verification of transactions, immutability of records, and resistance to compromise of individual nodes. A multi-tiered system architecture is proposed, including subsystems for identification, access control, event registration, cryptographic protection, and anomaly monitoring. Particular attention was paid to aligning the designed model with the requirements of the Federal Service for Technical and Export Control of Russia for threat modeling and the provisions of GOST R 34.10-2012 on electronic digital signatures. An integrated security indicator was developed to assess the integrity, availability, and confidentiality of data.

Possibilities to use distributed ledger technology are shown referring to storing data in information systems of airports and aviation systems of various levels. The features of the operation of a distributed ledger are noted regarding information systems. Various options for generating messages for storage using distributed ledger technology are studied along with the parameters of message flows. The features of using blockchain technology when creating distributed ledger are highlighted in case of the need to correct the stored information. Apossibility to use network technologies is shown for forming distributed ledger, the nodes of which are located at significant distances from each other (registries of several airports). The provided data can be used to create reliable distributed information storage facilities, both within a separate airport and for a group of airports.

The article explores the theoretical and methodological principles of integrating the organizational and economic potential of Blockchain technologies into the agribusiness system in the context of increasing demands for transparency and sustainability of value chains. The essence of Blockchain is revealed as a tool for forming a trusted information infrastructure that ensures data immutability, transaction automation and business process optimization based on smart contracts. It is substantiated that the use of distributed ledger technologies contributes to the decentralization of management, reduction of transaction costs, digitalization of product quality control and increase of the export potential of agricultural enterprises. Scientific approaches to the development of Blockchain solutions for agri-food supply chains are analyzed. A mechanism for integrating Blockchain into centralized and decentralized agribusiness platforms is proposed, which involves the development of digital competencies, the creation of support infrastructures and indicators for assessing the readiness of enterprises to implement distributed ledger technologies.

Pursuing the purpose of effective functioning in today's conditions, the business is forced to transform rapidly, to modernize at all levels. The world is changing, erasing the limits of its certainty. Companies need quality trans- formations and strategies that are effective in the face of rapid change towards "deep" digitization. Massive corporate management systems increasingly need the flexibility to keep pace with change. And companies with an innovative cul- ture are more in need of creative tasks than implementing detailed regulations. In the post-industrial time of digital economy, issues related to the development of the information sphere, the media and communications, the usage of modern information systems to develop the economy and stabilize social development as a whole, come first. The basic principles of practical application of Block- chain are investigated in the work. The stages of development of Blockchain technology, the stages of development of Blockchain technologies by time, the application of distributed registry technology in Blockchain applications, the principles of construction and operation of Blockchain have been specified. The benefits of using NEM for business are substantiated and the components of Proxima X technology, protocols and service layers, on-line and off-line proto- cols, decentralized applications are exposed.
