Update on Method C AI Oracle Porting and MDK Testing

Quantum Blockchain Technologies plc (AIM: QBT), the AIM-listed investment
company focused principally on a research, development and investment programme
within blockchain technology, is pleased to provide an update on the ongoing
development and testing of its Method C AI Oracle software on the ASIC
manufacturer’s mining rig and Mining Development Kit (“MDK”).

Further to the Company’s announcement of 8 April 2026, QBT confirms continued
progress on its accelerated testing strategy, aimed at demonstrating the
performance of its AI Oracle.

Key Technical Progress

The Company has now achieved three important milestones which establishes a
fully operational testing environment:

·               Modification of the mining rig operating system, including
changes to the micro-controller code, enabling the generation of structured
mining data streams to feed the AI learning engine;

·               Completion of the AI Oracle integration within the server-side
operating system, allowing mining jobs to be intercepted, analysed and optimised
before execution; and

·               Successful assembly and activation of the ASIC manufacturer’s
MDK, enabling live testing and real-time data collection in QBT’s laboratory.

Together, these developments allow QBT to operate a complete end-to-end test
architecture in which the AI Oracle evaluates mining jobs and selectively
executes only the most promising hashes, with the goal of improving mining
efficiency.

Testing Progress and Timeline

Data collection is now underway and represents a critical step towards training
the AI models. As data volumes increase, QBT expects to:

·               initiate neural network training;

·               generate ASIC-specific AI models;

·               conduct extended validation testing; and

·               deliver preliminary performance results, followed by a live
demonstration.

The MDK-based approach has accelerated the early stages of testing compared to
the original plan; however, further time and data is required for model training
and validation to ensure robust and reliable preliminary results.

Industry Engagement

The Company also confirms that QBT representatives met with the ASIC
manufacturer at the recent Bitcoin 2026 conference, where progress was presented
and the next phases of development were agreed. Further positive discussions
were held with other key industry representatives, proving a growing interest in
the AI Oracle among ASIC manufacturers.

Next Steps

QBT’s immediate focus is on expanding data collection, refining the AI model and
progressing towards preliminary results. In parallel, the Company continues to
work on porting the AI Oracle directly onto a mining rig control board, which
remains a key commercial objective.

Francesco Gardin, CEO and Executive Chairman of QBT, commented, “We are making
solid progress in establishing a fully operational testing environment for
Method C and are now generating the data required to train and refine our AI
models. The combination of system-level changes, successful integration of the
AI Oracle and activation of the MDK allows us to accelerate testing and move
closer to demonstrating real-world performance.

“I was also pleased to meet with the ASIC manufacturer at Bitcoin 2026, where we
presented our progress and aligned ourselves on the next stages of development.
We look forward to reporting preliminary results to this company within the next
couple of weeks.”
