Experts warn of potential quantum disruption to blockchain security

A survey by the Global Risk Institute has highlighted growing concern that quantum computing could undermine the cryptographic foundations of cryptocurrencies within the next decade.

Experts estimate a 28% to 49% probability that quantum machines capable of breaking current encryption standards could emerge within 10 years, with the probability rising further over a 15-year horizon.

Cryptocurrencies such as Bitcoin rely on public-key cryptography to secure transactions and verify ownership. Advanced quantum algorithms could reverse-engineer private keys from public data, exposing wallets and weakening blockchain security.

The risk is seen as particularly relevant for long-term stored assets and static addresses. Industry researchers and technology firms are already exploring post-quantum cryptography to mitigate potential disruption.

Efforts led by standards bodies such as the National Institute of Standards and Technology focus on developing encryption methods resistant to both classical and quantum attacks, although full migration across decentralised systems remains complex.

The findings place quantum readiness alongside broader digital security priorities, as financial systems, communications networks, and public infrastructure share similar cryptographic dependencies.

The evolving timeline is prompting early-stage preparation across the cryptocurrency ecosystem, where system upgrades must balance security, decentralisation, and continuity.

New quantum threat could weaken cryptocurrency encryption systems

A new warning from Google says advances in quantum computing could weaken widely used cryptographic systems protecting cryptocurrencies and digital infrastructure. A new whitepaper suggests future quantum machines may need fewer resources than previously estimated to break elliptic curve cryptography.

The research focuses on the elliptic curve discrete logarithm problem, which underpins much of today’s blockchain security. Findings suggest quantum algorithms like Shor’s could run with fewer qubits and gates, increasing concerns about cryptographic resilience.

To address the risk, the paper recommends a transition to post-quantum cryptography, which is designed to resist quantum attacks. It also outlines short-term blockchain measures, including avoiding reuse of vulnerable wallet addresses and preparing digital asset migration strategies.

Google also introduced a responsible disclosure approach using zero-knowledge proofs to communicate vulnerabilities without exposing exploitable details.

The company says this balances transparency and security, supporting coordinated efforts across crypto and research communities to prepare for quantum threats.

UK-backed SPOQC mission launches to test space-based quantum communications

A UK-led research mission aimed at advancing space-based quantum communications has launched aboard a SpaceX Transporter-16 rocket from Vandenberg Space Force Base in California. The Satellite Platform for Optical Quantum Communications, or SPOQC, was developed under the Integrated Quantum Networks (IQN) Hub led by Heriot-Watt University and was launched on 30 March 2026.

The mission builds on research and development carried out first through the Quantum Communications Hub and later through the IQN Hub, both funded by the Engineering and Physical Sciences Research Council. Five UK research institutions are involved in the collaboration, which is intended to strengthen UK capabilities in space-based quantum communications as governments and researchers prepare for the cybersecurity implications of more powerful quantum computing systems.

SPOQC is now in the final stages of commissioning before it begins transmitting quantum signals to receivers at the Hub Optical Ground Station at Heriot-Watt University in Edinburgh. The CubeSat is operating in a low Earth, Sun-synchronous orbit and passes over the UK about twice a day, with most measurements expected to take place during night-time passes, when experimental conditions are more favourable.

The mission’s wider policy relevance lies in its connection to the UK’s National Quantum Strategy, which views quantum technologies as important to national resilience, digital infrastructure, and long-term competitiveness. The project presents satellite-based systems as the most practical route towards resilient international quantum communication, since terrestrial fibre links face distance-related limitations that can degrade quantum signals over time.

A distinctive feature of the mission is its dual quantum source payload. One source uses discrete quantum signals at the single-photon level and was developed by the University of Bristol team, while the other uses continuous-variable signals and was developed by researchers at the University of York. Both connect to dedicated receivers at the optical ground station, allowing researchers to compare two established but technically different communication methods under varying atmospheric and orbital conditions.

‘The SPOQC mission is the culmination of outstanding collaborations between leading UK Universities, STFC RAL Space, and external industry partners. It offers a world-first platform to critically compare different quantum communication modalities, including the first use of continuous variable approaches from space. Through the IQN Hub, the SPOQC mission is a vital enabler towards truly global quantum communication via integration into terrestrial UK networks.’, said Professor Gerald Buller, Director of the IQN Hub.

The collaboration brings together the Universities of Bristol, Heriot-Watt, Strathclyde and York, alongside the Science and Technology Facilities Council’s RAL Space. STFC RAL Space contributed engineering, systems integration and mission support, while Heriot-Watt is operating the optical ground station. ISISPACE provided the satellite and technical support.

Researchers say the mission will also test whether quantum technologies can be scaled down to a 12U CubeSat, roughly the size of a microwave oven, as a proof of concept for future compact and lower-cost satellite quantum networks. SPOQC follows the November 2025 launch of SpeQtre, a UK-Singapore collaboration led by STFC RAL Space and SpeQtral, making it the second quantum mission supported by UK research to launch within six months.

Full quantum communication experiments are expected to begin in the second half of 2026 once commissioning is complete. Professor Tim Spiller from the University of York said: ‘As Director of the preceding Quantum Communications Hub, it is very pleasing to see six years of R&D by that Hub team to develop SPOQC and HOGS finally be rewarded with the launch of SPOQC. However, this will add a crucial link to the UK’s expanding quantum networking capability. I look forward to the first quantum demonstrations from SPOQC and HOGS later this year.’

Andy Vick, Disruptive Technology Programme Lead at STFC RAL Space, said: ‘The launch of two quantum CubeSats in close succession highlights the UK’s growing leadership in quantum technology. While both missions share a common satellite platform, SPOQC has united new partners to address new challenges. The RAL Space team is proud to have contributed from the outset, working closely with the Quantum Communications Hub, whose initial work laid strong foundations for the mission, and now supporting its delivery under the leadership of the IQN Hub. SPOQC is a big step for all the teams involved, one that we hope will pave the way for the UK’s national quantum network mission.’

Dr Kedar Pandya, Executive Director of EPSRC’s Strategy Directorate, said: ‘The SPOQC mission is a powerful example of how UK research leadership is shaping the future of secure global communications. By uniting world-class expertise across our quantum research hubs, we’re demonstrating not only scientific excellence but real technological ambition. This launch marks a major step toward quantum-secure networks that will help safeguard the UK’s digital infrastructure for decades to come.’

Google sets 2029 deadline for post-quantum cryptography migration

A transition to post-quantum cryptography by 2029 is being led by Google, aiming to secure digital systems against future quantum computing threats instead of relying on existing encryption standards.

The move reflects growing concern that advances in quantum hardware and algorithms could eventually undermine current cryptographic protections, particularly through attacks that store encrypted data today for decryption in the future.

Quantum computers are expected to challenge widely used encryption and digital signature systems, prompting the need for early transition strategies.

Google has updated its threat model to prioritise authentication services, recognising that digital signatures pose a critical vulnerability if not addressed before the arrival of quantum machines capable of cryptanalysis.

The company is encouraging broader industry action to accelerate migration efforts and reduce long-term security risks.

As part of its strategy, Google is integrating post-quantum cryptography into its products and services.

Android 17 will include quantum-resistant digital signature protection aligned with standards developed by the US’s National Institute of Standards and Technology. At the same time, support has already been introduced in Google Chrome and cloud platforms.

These measures aim to bring advanced security technologies directly to users instead of limiting them to experimental environments.

By setting a clear timeline, Google aims to instil urgency and direction across the wider technology sector.

The transition to post-quantum cryptography is expected to become a critical step in maintaining online security, ensuring that digital infrastructure remains resilient as quantum computing capabilities continue to evolve.

Quantum readiness gains momentum according to OECD report

The OECD (Organisation for Economic Co-operation and Development) highlights how businesses are preparing for quantum computing, recognising it as a transformative technology instead of relying solely on conventional computing methods.

Quantum readiness is framed as a long-term capability-building effort in which firms gradually develop skills, infrastructure, and partnerships to explore commercial applications while navigating uncertainty.

Drawing on research, surveys, and interviews with public and private organisations across 10 countries, the OECD identifies both the practical steps companies take to build readiness and the barriers that slow adoption.

Early efforts focus on low-cost awareness and exploration, including attending workshops, training sessions, and industry events, allowing firms to familiarise themselves with emerging opportunities instead of waiting for fully mature systems.

Despite growing interest, companies face significant challenges. Technological immaturity complicates pilots and feasibility studies, while many firms lack a clear understanding of potential business applications.

Access to quantum resources, funding for research and development, and staff training are expensive, particularly for small- and medium-sized enterprises. Furthermore, there is a shortage of talent with both quantum computing expertise and domain-specific knowledge.

As a result, readiness tends to be concentrated among large, R&D-intensive firms, while smaller companies often recognise quantum computing’s potential but delay action.

Such an uneven adoption risks creating a divide in the digital economy, with early adopters moving ahead and other firms falling behind instead of engaging proactively.

To address these challenges, the OECD notes that public and private support mechanisms are critical. Networking and collaboration platforms connect firms with researchers, technology providers, and industry peers, fostering knowledge exchange and collective experimentation.

Business advisory and technology extension services help companies assess capabilities, test solutions, and access specialised facilities.

Grants for research and development lower the costs of experimentation and encourage collaboration, while stakeholder consultations ensure that support measures remain aligned with business needs.

Many companies are also establishing internal quantum labs and innovation hubs to trial applications and build expertise in a controlled environment, combining research with practical exploration instead of relying solely on external guidance.

Looking ahead, the OECD recommends expanding education and skills pipelines, strengthening industry-academic partnerships, and designing policies that support broader participation in quantum adoption.

Hybrid approaches that integrate quantum computing with AI and high-performance computing may offer practical commercial entry points for early applications.

Policymakers are encouraged to balance near-term exploratory pilots with forward-looking support for software development, interoperability, and workforce growth, enabling firms to move from experimentation to deployment effectively.

By following OECD guidance, companies can enhance innovation, improve competitiveness, and ensure that readiness efforts span sectors and geographies rather than remain limited to a few early adopters.
