Methodology for Synthesizing Quantum-Resistant Blockchain Platforms With Cyber-Immunity

Purpose of the research: development of a methodology for the parametric synthesis of cyber-resilient blockchain ecosystems and platforms of the ‘Data Economy’ of the Russian Federation with cyber-immunity under the new quantum threat. Methods of the research: methods of system analysis, methods of probability theory and mathematical statistics, methods of the theory of stability of complex systems, methods of similarity and dimensionality theory. Result of the research: an study of existing approaches to ensuring quantum resilience of blockchain platforms with cyber-immunity has been conducted; a hypothesis regarding the possibility of ensuring the required cyber-resilience of blockchain platforms with cyber-immunity under quantum attacks has been formulated; a methodology for the parametric synthesis of quantum-resilient blockchain ecosystems and platforms of the ‘Data Economy’ of the Russian Federation with cyber-immunity has been developed using similarity theory methods; experimental studies of the methodology have been carried out, the results of which confirmed the proposed hypothesis. Scientific novelty: the proposed methodology differs from existing ones in that it introduces new groups of formal operations for each level of blockchain platforms with cyber-immunity functionality, aimed at evaluating the necessary and sufficient values of neutralizing impact parameters using similarity theory methods. Additionally, it includes a criterion that allows establishing the existence of a solution for the given values of required cyber-resilience and time performance indicators of the blockchain platform.
