Introduction

In the past few years, systems based on the so-called blockchain have gained great popularity, attracting users with a number of their advantages: decentralization, data immutability, transparency, as well as the absence of a trusted center, that is, an intermediary. Providing such benefits is possible thanks to two “whales” of the blockchain: asymmetric encryption and the use of hash functions . However, in connection with the development of quantum computing, the security of these primitives has become under threat, so there is a need to find new approaches to building a blockchain that will be resistant to attacks using a quantum computer - the so-called post - quantum blockchain.... This article highlights which parts blokcheyna are the most vulnerable to attack by a quantum computer, how real are these threats, what are the approaches to the construction postkvantovogo blokcheyna resistant to them, and how these approaches are applicable.
