  For the successful development of the astrophysics and, accordingly, for
obtaining more complete knowledge of the Universe, it is extremely important to
combine and comprehensively analyze information of various types (e.g., about
charged cosmic particles, gamma rays, neutrinos, etc.) obtained by using divers
large-scale experimental setups located throughout the world. It is obvious
that all kinds of activities must be performed continually across all stages of
the data life cycle to help support effective data management, in particular,
the collection and storage of data, its processing and analysis, refining the
physical model, making preparations for publication, and data reprocessing
taking refinement into account. In this paper we present a general approach to
construction and the architecture of a system to be able to collect, store, and
provide users' access to astrophysical data. We also suggest a new approach to
the construction of a metadata registry based on the blockchain technology.
