Distributed forecasting of agriculture commodity prices has an attractive research perspective that delivers active breakthrough analysis of the rapid fluctuations in pricing forecasts for participating stakeholders without being manually dispatched lists. The increased use of an efficient forecasting mechanism for the agriculture information management of generated records and processing creates emerging challenges and limitations. These include new government mandates and regulations, the price of land for expansion, forecasting the growing demand for commodities, fluctuations in the global financial market, food security, and bio-based fuels. Building and deploying distributed dynamic scheduling, management, and monitoring systems of agricultural activities for commodity price forecasting and supply chains require a significant secure and efficient approach. Thus, this paper discusses a collaborative approach where two different folds are demonstrated to cover distinct aspects with different objectives. A metaheuristic-enabled genetic algorithm is designed to receive day-to-day agricultural production details and process and analyze forecast pricing from the records by scheduling, managing, and monitoring them in real-time. The blockchain hyperledger sawtooth distributed modular technology provides a secure communication channel between stakeholders, a private network, protects the forecasting ledger, adds and updates commodity prices, and preserves agricultural information and node transactions in the immutable ledger (IPFS). To accomplish this, we design, develop, and deploy two distinct smart contracts to register the system’s actual stakeholders and allow for the addition of node transactions and exchanges. The second smart contract updates the forecasting commodity pricing ledger and distributes it to participating stakeholders while preserving detailed addresses in storage. The simulation results of the proposed collaborative approach deliver an efficient E-agriculture commodity price forecast with an accuracy of 95.3%. It also maintains ledger transparency, integrity, provenance, availability, and secure operational control and access of agricultural activities.

The article addresses the potential of using social networks in social education and for solving the problems of youth socialization. There is an urgent social need for the harmonious development of the child's personality, including in the Internet environment. At the same time, there is insufficient knowledge about the organization of education in social networks in science. The article identifies the experience of successful interaction between teachers and students on the Internet and ways of organizing event situations in social networks. The study was conducted in February-October 2020 and analysed the content of open official accounts of educational organizations in the social networks ‘VKontakte’, Instagram and documents of educational organizations. The complex use of observation methods, quantitative data processing, expert assessments was aimed at identifying forms of educational activity that are promising for implementation online in social networks. The study showed that, despite the variety of topics and styles, the content of official school accounts resembles a list of news about holidays and other public events. The accounts do not contain materials that could cause vivid emotions and sensations in children, become a source of experiences, value attitudes, experience of interacting with people. Consequently, schools do not provide children with opportunities for self-knowledge, self-determination, self-realization, and do not support their initiatives in social networks. The article recommends that schools expand the practice of organizing networked educational events. For this, they need to create groups of different ages for children and adults for joint planning, organizing, conducting, summing up creative deeds. The maintenance of a thematic Instagram account of a school is offered as an example of a successful subject-subject interaction between a teacher-educator and students in social networks.
