Bitcoin moves closer to quantum resistance with BIP-360

BTQ Technologies has deployed Bitcoin Improvement Proposal BIP-360 on its Bitcoin Quantum Testnet v0.3.0, marking the first live test of the proposal. The upgrade introduces a quantum-resistant transaction model, Pay-to-Merkle-Root, designed to strengthen Bitcoin’s long-term security.

BIP-360 focuses on mitigating a vulnerability linked to Taproot’s key-path spending mechanism, which can expose public keys on-chain. Such exposure may become a risk if future quantum computers are capable of exploiting cryptographic weaknesses using advanced algorithms.

The testnet adds new consensus rules, post-quantum signatures, and full transaction lifecycle testing. Faster one-minute block times and adjusted fee structures have been introduced to accommodate larger and more complex signatures.

Growing global attention on quantum threats adds urgency to the development. US, EU, and Canadian authorities are setting timelines for post-quantum cryptography to protect future system security.

UK Government commits up to £2 billion to quantum technologies

The UK Government has announced up to £2 billion in funding for quantum technologies, including more than £1 billion over the next four years, confirmed by UKRI in December 2025, and a new procurement programme called ProQure designed to support the scaling of quantum computing across the UK.

The announcement is being billed as the country’s ‘Quantum Leap’, positioning the UK as a first mover in quantum commercialisation.

The funding is distributed across several areas: over £500 million for quantum computing to help companies scale and develop applications in pharmaceuticals, financial services, and energy; £125 million for quantum networking; and £205 million for quantum sensing and navigation, with dedicated applications in medical diagnostics, greenhouse gas monitoring, and ultra-secure communications.

A further £13.8 million will be injected into the UK’s five National Quantum Research Hubs, with an additional £90 million for quantum infrastructure and £20 million for skills and commercialisation programmes.

techUK welcomed the announcement, noting that the UK is already home to 11% of the world’s quantum startups and has attracted 12% of global quantum private equity investment.

The trade association highlighted the ProQure procurement programme as a step in the right direction, but cautioned that sustained, long-term private investment will be essential to support deep-tech companies through lengthy development cycles.

Britain targets quantum leadership with £1bn investment

UK Secretary of State for Science, Innovation and Technology Liz Kendall has announced a £1bn funding package to boost UK quantum computing and retain domestic talent.

The initiative reflects growing concern over the country’s ability to compete globally, particularly after the US established dominance in AI.

Officials emphasised the need to retain British startups, engineers, and researchers who often relocate abroad in search of better funding and scaling opportunities. The UK produces top talent, but Google and OpenAI own many leading firms.

The investment will support the development of large-scale quantum computers for use across science, industry, and the public sector. Another £1bn will fund real-world use in finance, pharmaceuticals, and energy.

The government aims to build a fully operational domestic quantum system by the early 2030s.

Quantum computing uses qubits that can exist in multiple states simultaneously, enabling far greater computational power than classical systems. Fully fault-tolerant machines are still in development, but the technology could drive advances in drug discovery, materials science, and complex modelling.

Quantum Computing transforms port scheduling and maritime logistics optimization

Quantum computing is emerging as a complementary technology in maritime shipping, an industry defined by constant constraints, disruptions, and interdependent decisions. As global trade networks grow more complex, optimisation challenges in ports and logistics systems are becoming increasingly complex to solve with classical computing alone.

In hybrid workflows, classical systems manage data and operations, while quantum routines tackle the most computationally intensive bottlenecks.

The main difficulty in maritime logistics is not the volume of data, but the exponential growth in the number of possible decisions as constraints accumulate. Real-world variables such as weather, labour rules, emissions targets, congestion, and intermodal coordination make planning significantly more complex.

Problems, including berth allocation, crane sequencing, vehicle routing, fleet scheduling, and container loading, often require simplifications. Under time pressure, planners frequently settle for “good enough” solutions.

Quantum computing is particularly suited to dense, constraint-heavy optimisation tasks. In hybrid systems, it can improve replanning during disruptions and generate higher-quality scheduling options.

Early experimentation is underway in major ports, including initiatives in Los Angeles and Dubai. These pilots focus on measurable operational gains and technical readiness.

While hardware continues to mature, software accessibility remains a key barrier. Maritime leaders are encouraged to invest in modelling capabilities and integration planning to prepare for the gradual adoption of quantum.

Bitcoin cryptography safe as quantum threat remains distant

Quantum computing concerns around Bitcoin have resurfaced, yet analysis from CoinShares indicates the threat remains long-term. The report argues that quantum risk is an engineering challenge that gives Bitcoin ample time to adapt.

Bitcoin’s security relies on elliptic-curve cryptography. A sufficiently advanced quantum machine could, in theory, derive private keys using Shor’s algorithm, which requires millions of stable, error-corrected qubits, and remains far beyond current capability.

Network exposure is also limited. Roughly 1.6 million BTC is held in legacy addresses with visible public keys, yet only about 10,200 BTC is realistically targetable. Modern address formats further reduce the feasibility of attacks.

Debate continues over post-quantum upgrades, with researchers warning that premature changes could introduce new vulnerabilities. Market impact, for now, is viewed as minimal.
