Business Update

 

Quantum Blockchain Technologies (AIM: QBT), a Research & Development and
investing company focused on an intensive R&D programme to disrupt the
blockchain technology sector announces that following its attendance at
Bitcoin 2025 conference in Las Vegas, where it presented its AI technology for
Bitcoin mining to selected potential partners and customers, that it is now
engaged in discussions with two companies to port its Method A and Method B AI
technologies onto their existing aftermarket control boards. This segment of
the market represents a significant user base and provides, the Board
believes, the quickest route to market for two of QBT's software products.

 

As previously reported, the Company confidently believes its three Methods
(namely Method A, Method B and Method C) represent a breakthrough achievement
in the industry and, in Las Vegas, the Company demonstrated compelling
evidence that using its proprietary AI to increase the quality hashing
performance was a reality. In one example, for Method A, this was accomplished
by running two identical ASIC miners, in real-time mining mode, with the same
clock frequency and thermal conditions; one mining with its native GCminer
operating system and one with a modified CGminer, which included QBT AI
software. The results clearly showed that using QBT AI software resulted in
producing more pool rewards per unit of time.

 

 

Deploying Method A and Method B on existing mining platforms

 

After careful review of the market's needs, QBT is focused on working with
companies who deploy aftermarket control boards on their Bitcoin miners. These
boards often replace the manufacturer's original control boards installed in
any typical mining rig, especially in the market leading mining machines
predominantly manufactured by Chinese companies. The reason for aftermarket
optimisation is due to the improvement of the mining performance of the ASIC,
the size of the processing engine of the mining rigs, which is achieved by
physically optimising the hash rate and the energy costs, by overclocking,
reducing voltage, monitoring the ASIC temperature, and a number of other
efficiencies. In the Bitcoin mining sector, less than ten companies have
undertaken the cost and effort to redesign the firmware of the control boards,
as it represents a substantial investment.

 

Therefore, due to widespread standard practice of optimising control boards,
implementing the porting of QBT's CGminer and ESPminer software modifications
onto aftermarket control boards does not represent a technical barrier, since
the small changes required to both the operating system software and the core
firmware can be simply implemented by aftermarket control board suppliers
under QBT specifications.

 

The Company's technical team believes that uploading QBT's modified firmware
and software to aftermarket control boards would be a seamless upgrade,
similar to what is normally and routinely performed by the provider of such
aftermarket boards when updating their current versions of their software and
firmware.

 

The Board believes this commercial direction will allow the immediate release
and sale of Methods A and B, while a live connection to QBT's servers running
QBT's AI learning models is anticipated to guarantee control of the use of the
Methods by the customers.

 

QBT will, therefore, look to deploy its technology in partnership with the
aftermarket control board providers mainly on miners produced by the leading
Chinese mining rig manufacturers where tens of thousands of aftermarket
control boards are currently installed. This segment of the Bitcoin mining
market represents the largest share of machines currently in use, in addition
it comprises the new US mining rig producers, all of whom attended Bitcoin
2025.

 

 

Method C - Design integration

 

The Board is also pleased to report that QBT is now engaged with two ASIC chip
manufacturers, both of whom will shortly commence an in-depth assessment of
Method C and its architectural implementation integration within the existing
design of their own ASICs, new versions of which are currently under
development.

 

 

Francesco Gardin, CEO and Chairman of QBT, commented: "The Company is finally
entering into the on-site third-party assessment phase with potential
customers and partners. The live and off-line demonstrations of QBT's
technology in Las Vegas proved to be essential in convincing some of the major
players that the ability to make predictions on the behavior of SHA-256 using
AI learning models is indeed, real, as it provides a practical solution to
improve the quality hashing power of a miner."

 

"We are now moving fast from the single ASIC implementations of Method A and
Method B to the mining rig versions in order to deploy to potential customers
and partners QBT technology, while for Method C we are working hard to
integrate our product into the new versions of the ASIC chips of two Bitcoin
mining manufacturers."

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.

 

ESPminer: a recently developed public domain operating system for Bitcoin
mining devices, based on the ESP32 microcontroller.

 

Method A: A machine learning based development by QBT R&D team, aimed at
reducing the SHA256 search space, compared to the brute force method used by
BTC mining rigs today.

 

Method B: A machine learning and statistical optimisation technologies
developed by QBT R&D team, reducing the SHA-256 search space, but radically
different from Method A.

 

Method C: A machine learning based development by QBT R&D team which is
composed by an AI model to be trained and an AI Oracle (the result of the
training of the model). The AI Oracle assesses in real time the likelihood of
an input to SHA-256 to generate a winning hash.

 

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
