Launch of Method C Software Version

 

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 announce the development
of a software-only version of QBT's Method C AI Oracle.

 

This new software version of Method C has been under development for the past
10 months, but only in the last three months have satisfactory results started
to emerge, following a radical new approach, by the R&D team, to the training
of the AI Model which generates the Oracle.

 

This software-only version of Method C is integrated directly into CGMiner and
similar operating systems running on the control boards of Bitcoin mining
rigs.           

 

Unlike the hardware version of Method C (as discussed on 19 June 2025         
                       
https://www.londonstockexchange.com/news-article/QBT/business-update/17094621 
                             ), which requires implementation onto the ASIC
chip,                     the performance of this new software-only version
is independent of the ASIC being used in the miner. This represents a major
breakthrough for QBT, with time to market and initial capex costs for
customers are expected to be reduced significantly.

 

Over the past month, testing of the new software-only version in the Company's
Milan laboratory has shown an average improvement in mining efficiency of over
10% - meaning, its capability of finding the winning hash at over 10% above
the minimal difficulty threshold as set by most mining pools.            

 

Further, the new software-only version of Method C has an additional
commercial advantage, as it works in conjunction with the original hardware
Oracle version of Method C to deliver compound efficiencies in Bitcoin mining.

 

A collaboration is currently under way with a US-based ASIC manufacturer to
test this new approach on their commercial miners.

 

The Company is also in advanced discussions with other US based ASIC
manufacturers in the expectation that similar test programmes on their mining
rigs will follow.           

 

Towards this, the Company is attending Mining Disrupt in Dallas, Texas from 11
         th           to 13th November 2025.           

 

 

Francesco Gardin, CEO and Executive Chairman of QBT, commented                
   , "The last six months have been crucial for this major R&D achievement
which has involved, among other things, the generation of a staggering amount
of mining data for the training of the new AI model.           

 

"We can confirm that US-based ASIC manufacturers are making enquiries with us
about our technology, as it potentially offers a key competitive element to
take their miners from `hashing-rate' only performance, to quality hash
generation. We will be hosting a number of meetings with miners at Mining
Disrupt this week; some will be follow-up meetings from the summer conference
and some are with new miners."

Glossary of Terms

 

ASIC                    : An Application-Specific Integrated Circuit is an
integrated circuit chip customized for a particular use, rather than intended
for general-purpose use. ASIC chips are typically fabricated using metal-oxide
semiconductor (MOS) technology, as MOS integrated circuit chips.

 

CGminer                    : Is the most popular software system for
GPU/FPGA/ASIC based miners. CGminer is an open-source GPU miner written in C
available for several platforms like Windows, Linux and OS X.

 

Method C Hardware                    : QBT's proprietary logic gate
architecture implementation of the AI Oracle to assess in real time on the
ASIC the likelihood of an input to SHA-256 to generate a winning hash above
given level of difficulty.

 

Method C Software:                     A software version of the Method C
Oracle that can be integrated directly into CGMiner, or similar operating
systems running on the control boards of Bitcoin mining rigs, to assess the
likelihood of headers to SHA-256 to generate a winning hash above given level
of difficulty.

 

SHA-256                    : Secure Hashing Algorithm (SHA)-256 is the hash
function and mining algorithm of the Bitcoin protocol, referring to the
cryptographic hash function that outputs a 256 bits long value
