Quantum Blockchain Technologies PLC (AIM:QBT, FRA:BYA1), in its financial results statement for 2025, highlighted that it had moved closer to live deployment of its Bitcoin mining technology, though losses widened and the company ended the year with net current liabilities before later extending its bond maturities.
QBT said its Method C AI Oracle made “significant progress” during the year, including a new patent application covering binary decision trees, live Bitcoin mining tests on current blockchain blocks and an approximate 30% mining advantage in FPGA-based live testing compared with the same hardware without the AI Oracle.
A software-only version of Method C was described by the board as one of the company’s most commercially significant milestones to date, because it is designed to integrate into mining software environments such as CGMiner rather than directly into ASIC chip architecture. QBT said this had helped discussions with ASIC manufacturers, including non-disclosure agreements and the provision by one manufacturer of dedicated mining hardware, source code and technical documentation.
The AIM-listed digital asset R&D company reported a total comprehensive loss of €3.13 million for the year to 31 December 2025, compared with €2.85 million in 2024. Operating losses were broadly steady at €2.95 million, while cash declined to €451,000 from €604,000.
After the year-end, QBT raised £500,000 before expenses at 0.35p per share, extended the maturity of its bonds to December 2028, advanced Method C testing through an ASIC manufacturer’s Mining Development Kit and agreed to sell its remaining 23.39% stake in Forcrowd Srl for €155,000.
