Organization of data gathering and preparing on the basis of blockchain for the supporting system of making decisions in the sphere of developing human capital of region

In the context of establishing the digital economy there appears the necessity to apply innovative methods of processing increasing volumes of data on digital platforms with the use of intellectual computer systems. The necessity of creating a subsystem for gathering digital data is substantiated in this work; this subsystem should meet modern requirements for the quality of these data in terms of reliability, targeting and security. The authors have suggested a model of digital accounting of data on labor activity of individuals with the use of the blockchain technology and smart-contracts with the aim of providing the required quality of the data. In this case, the blockchain technology provides reliable preservation and authenticity of data and the system of smart-contracts presents the data in a convenient form for any consumers of this information. It has been demonstrated in this work that the subsystem of digital accounting in labor sphere will allow for creating a unified information environment for cooperation of all subjects. The collected data can be successfully used in support systems for making decisions in the field of development of the human capital of the region. In this case the system of smart-contracts plays a key role and acts as an integration bus which provides cooperation of the blockchain subsystem with the automated subsystem of intelligent data processing.
