ABSTRACT The emergence of quantum computing represents a paradigm shift with dual implications for the future of cryptocurrency: it poses an existential threat to current systems while simultaneously enabling revolutionary new ones. This paper analyzes the economic implications of this transition. We examine the vulnerabilities of classical cryptocurrencies like Bitcoin and Ethereum to quantum attacks via Shor's and Grover's algorithms and explore the rise of quantum-resistant cryptocurrencies (e.g., QRL, IOTA). Furthermore, we investigate the theoretical foundations of fully quantum-native systems, which leverage superposition, entanglement, and the no-cloning theorem to enable secure quantum money and novel consensus mechanisms. Key challenges such as quantum decoherence, scalability, and the necessity for hybrid transitional systems are addressed. The economic analysis contrasts the energy efficiency and hardware requirements of classical versus quantum mining, projecting a pathway towards greener and more efficient processes. The concept of "quantum money" is introduced as a tamper-proof currency, with potential applications in decentralized finance (DeFi) and central bank digital currencies (CBDCs). We also discuss hypothetical dual-use threats, such as quantum-enabled money laundering, underscoring the technology's potential for both hyper-transparency and unbreakable anonymity. We conclude that the integration of quantum computing will be phased, beginning with defensive post-quantum cryptography and evolving into a fully quantum-economic paradigm. Proactive adaptation by policymakers and industry is essential to harness the benefits and mitigate the risks of this new era. |
