ABSTRACT
The work deals with the problem of ensuring the security of information storage in various registers, including state ones. First of all, we focused on security against attacks aimed at changing information in the registry, which is a constant and real threat today. The method proposed by us to prevent such attacks on changing information in the registry is based on the use of results from a relatively new direction in the field of information technology – blockchain technology. We propose building a so-called cascade structure of registers on blockchains using one of the newest consensus protocols called Proof-of-Proof. Such a cascade structure of registers, with the correct parameters of its construction and use, provides all the properties of correct information storage, such as non-failure, immutability, sequence of placement in the register, and others. After formulating the basic idea of building a cascade registry, we present a list of problems that need to be solved so that the probability of success of a substitution information attack is negligibly small.
