What Quantum Blockchain Technologies does

Quantum Blockchain Technologies Plc (AIM: QBT) is a UK-incorporated, publicly listed R&D technology company developing AI-driven Bitcoin mining optimisation technologies that combine machine learning, quantum computing, cryptography, and FPGA/ASIC design techniques. Its core product portfolio centres on three proprietary software methods — Method A (neural network-driven search-space selection), Method B (informed search across the 2^1024 hash space), and Method C (a real-time AI Oracle that assesses mining pool headers before SHA-256 processing) — delivered as SaaS client-server applications, supplemented by patented ASIC-level optimisations (ASIC UltraBoost, ASIC EnhancedBoost/MSFCA, and Binary Decision Trees) that reduce SHA-256 operations by approximately 7% and Message Schedule calculations by approximately 20%, while the Binary Decision Trees hardware implementation adds only 1-4% area and energy overhead.

The company generates no revenue at present and operates as a pre-commercialisation R&D entity with approximately seven R&D experts running live testing at a Milan University laboratory, supported by an in-house data centre in Northern Italy with 70,000+ GPU cores, 2 PB of storage, and IBM QISKIT quantum computer simulator access. Its commercial intent is to monetise through a mix of channels: SaaS subscriptions for Method A/B/C software, ASIC chip IP licensing, proprietary mining hardware and software access for selected partners, and hash-rate arbitrage via its newly incorporated Malta-based subsidiary BlocKeeper, which plans to acquire and manage hash rate without owning mining infrastructure. The targeted customer base comprises ASIC chip manufacturers (three under NDA) and Bitcoin mining pools, with planned North American cloud infrastructure for SaaS delivery.

QBT faces material risks: its patents are either filed-pending or facing rejections (USPTO Final Rejection on ASIC Ultra Boost, EPO novelty objections citing an Intel patent), it is reliant on a small number of unnamed ASIC partner relationships under NDA, and it must renegotiate or repay a €5.5 million zero-coupon bond whose maturity was extended from December 2026 to December 2028 subject to bondholder approval. As a shell-rebranded AIM penny stock with a market capitalisation of approximately £5.79 million and no revenue, the company is best characterised as an early-stage, technology-led R&D venture transitioning from concept to commercial pilot.

Products and services

• Method A AI-driven Bitcoin mining software that, at the start of each block hashing, decides whether to use brute-force search or a space-confined search strategy, exploiting SHA-256 computation behaviours to gain statistical advantage; delivered as a SaaS client-server application for mining rig operators.
• Method B Informed search Bitcoin mining software that guides hash discovery by identifying where the most promising winning hashes are likely to be found in the 2^1024 search space, using the degree of freedom from different header parameters; delivered as a SaaS client-server application via firmware upgrade.
• Method C AI Oracle (Software Version) Oracle software that performs real-time assessment of mining pool headers before SHA-256 submission, deciding which headers are worth processing and which can be skipped to save energy; runs as a SaaS client-server application on the mining rig's operating system for mining rig operators and ASIC manufacturers.
• ASIC UltraBoost Patent-protected ASIC hardware IP improving the Bitcoin mining process via three variants to the SHA-256 message scheduler for the three SHA-256 instances in mining, reducing Message Schedule calculations by approximately 20% and overall SHA256 operations by approximately 7%; licensed or integrated into ASIC chips for ASIC manufacturers.
• ASIC EnhancedBoost (MSFCA) Patent-protected ASIC hardware IP using Message Scheduling For Cryptographic Hashing (MSFCA) that enables partial pre-computation of future blockchain blocks asynchronously before the previous block is closed, saving logical gates and computation time on ASIC chips with projected SHA-256 ASIC chip area saving of approximately 8% on average; targeted at ASIC manufacturers.
• Implementation of Binary Decision Trees (Method C AI Oracle hardware IP) Patent-protected hardware implementation of the Method C AI Oracle on ASIC chips via Binary Decision Trees, requiring only approximately 1-4% additional double SHA-256 lane area and similar energy overhead while keeping SHA-256 lanes busy without performance impact; targeted at ASIC manufacturers.
• BlocKeeper virtual mining service Capital-light Bitcoin virtual mining service operating via the Malta-incorporated wholly-owned subsidiary that acquires and manages hash rate without direct investment in mining hardware or infrastructure, leveraging QBT's AI-driven mining technologies to optimize hash-rate deployment and profit from hash-rate arbitrage with hashpower providers, miners, brokers, and mining pools.
