The rise of quantum computing poses a serious threat to modern encryption systems, with experts warning that critical digital infrastructure could become vulnerable once quantum devices reach sufficient power.
Unlike classical computers that process binary bits, quantum computers use qubits, allowing them to perform vast numbers of calculations simultaneously.
This capability could make breaking widely used encryption methods, like RSA, possible in minutes—something that would take today’s computers thousands of years.
Although quantum systems powerful enough to crack encryption may still be years away, there is growing concern that hackers could already be collecting encrypted data to decode it once the technology catches up.
Sensitive information—such as national security data, intellectual property, and personal records—could be at risk. In response, the US National Institute of Standards and Technology has introduced new post-quantum encryption standards and is encouraging organisations to transition swiftly, though the scale of the upgrade needed across global infrastructure remains immense.
Updating web browsers and modern devices may be straightforward, but older systems, critical infrastructure, and the growing number of Internet of Things (IoT) devices pose significant challenges.
Satellites, for instance, vary in how easily they can be upgraded, with remote sensing satellites often requiring full replacements. Cybersecurity experts stress the need for ‘crypto agility’ to make the transition manageable, aiming to avoid a chaotic scramble once quantum threats materialise.

How does quantum computing threaten cryptocurrency?
Despite its potential benefits, quantum computing poses significant risks to the cryptocurrency ecosystem, depending on how it is used and who controls it:
Breaking public key cryptography Quantum computers equipped with Shor’s algorithm can decrypt ECC and RSA encryption. Tasks that would take classical computers millennia could be accomplished by a quantum computer in mere hours. This capability threatens to expose private keys, allowing hackers to access wallets and steal funds.
Mining oligopoly The mining process, vital for cryptocurrency creation and transaction validation, depends on computational difficulty. Quantum computers could dominate mining activities, disrupting the decentralisation and fairness fundamental to blockchain systems.
Dormant wallet risks Wallets with exposed public keys, particularly older ones, are at heightened risk. A quantum attack could compromise these funds before users can adopt protective measures.
With projections suggesting that quantum computers capable of breaking current encryption standards could emerge within 10–20 years—or perhaps even sooner—the urgency to address these threats is intensifying.
Solutions: Quantum-resistant tokens and cryptography
Where there is a challenge, there is a solution. The crypto industry is proactively addressing quantum threats with quantum-resistant tokens and post-quantum cryptography. Lattice-based cryptography, for example, creates puzzles too complex for quantum computers, with projects like CRYSTALS-Kyber leading the charge. Hash-based methods, such as QRL’s XMSS, ensure data integrity, while code-based cryptography, like the McEliece system, uses noisy signals to protect messages. Multivariate polynomial cryptography also adds robust defences through complex equations.
As we can see, promising solutions are already actively working to uphold blockchain principles. These innovations are crucial not only for securing crypto assets but also for maintaining the integrity of blockchain networks. Quantum-resistant measures ensure that transaction records remain immutable, safeguarding the trust and transparency that decentralised systems are built upon.
