Abstract Modern national blockchain ecosystems and platforms must account for emerging quantum threats. Currently, however, there are no formalized methods for the quantitative assessment of blockchain stability under adversarial quantum attacks. The development of such a methodology enables a quantitative evaluation of quantum impacts on various ecosystem components, the establishment of resilience metrics, and the prediction of potential compromise timelines for cryptographic primitives, given the capabilities of contemporary quantum hardware. This article proposes and substantiates an original method for analyzing the quantum resilience of national blockchain ecosystems – including those based on Enterprise Ethereum Alliance, Waves Enterprise (Waves, Vostok), Hyperledger Fabric (Linux, IBM), Corda Enterprise, Masterchain, and Microsoft Azure Blockchain. The proposed framework includes: (i) a mathematical model of blockchain stability accounting for diverse attack vectors; (ii) a resilience assessment methodology based on threat, vulnerability, and risk analysis; (iii) algorithms for evaluating cryptographic strength using modified Shor’s and Grover’s quantum algorithms; and (iv) an optimized Approximate Quantum Fourier Transform (AQFT) scheme to assess the feasibility of compromising blockchain cryptographic primitives.

Directions for enhancing quantum resilience of blockchain platforms and ecosystems

Blockchain ecosystems and platforms form a critical foundation for national digital economies worldwide. However, recent advancements in quantum computing, exemplified by breakthroughs from IBM and other leading developers, reveal that these systems may no longer guarantee stability and security against emerging quantum-enabled attacks. The increasing feasibility of such threats, commonly referred to as the “quantum threat,” poses unprecedented risks to the integrity, confidentiality, and reliability of blockchain infrastructures. In response, several technologically advanced countries have initiated efforts to anticipate and mitigate potential quantum cyberattacks. Ensuring the quantum resilience of blockchain systems necessitates novel approaches beyond conventional information security methods. Unlike traditional protections, these approaches aim to prevent systemic failures even under quantum-enabled adversarial conditions. The study identifies and systematizes the main directions for achieving quantum resilience, including post-quantum cryptographic primitives, modified quantum algorithms, and hybrid quantum–classical security models. The review highlights how progress in superconducting, ionic, photonic, and neutral-atom quantum platforms reshapes the threat landscape. A distinctive contribution of this work lies in its integrative perspective — linking cryptographic, architectural, and ecosystem-level aspects of blockchain sustainability under quantum threats. The proposed framework emphasizes combining post-quantum cryptography, quantum-safe protocols, and cross-domain coordination between quantum computing and cybersecurity research. Given the rapidly advancing nature of quantum technologies, the findings presented here not only reflect the current state of the field but also outline strategic directions for developing adaptive, quantum-resilient blockchain systems, including dynamic algorithmic frameworks, formal verification of quantum-resistant smart contracts, and simulation of blockchain protocols against quantum adversary models.
