Quantum Blockchain Technologies (QBT) has secured formal approval from the United States Patent and Trademark Office (USPTO) for its patent application covering the company’s ASIC UltraBoost technology, marking a significant step toward strengthening its intellectual property portfolio in Bitcoin mining hardware.
The patent application, titled Message Scheduling for Cryptographic Hashing, focuses on improving the efficiency of Bitcoin mining by eliminating redundant computations within the SHA-256 message scheduling process used in application-specific integrated circuit (ASIC) mining hardware. According to the company, the innovation is designed to streamline cryptographic hashing operations, potentially improving the performance of specialized mining chips.
Although the application has received formal approval, QBT clarified that the patent has not yet been officially granted. The company explained that several administrative requirements remain, including the payment of issue and publication fees, before the patent can be formally issued. It nevertheless expects the process to be completed in the near future.
The approved patent application centers on ASIC UltraBoost technology that is designed to reduce redundant SHA-256 computations, improving the efficiency of Bitcoin mining hardware while strengthening QBT’s intellectual property portfolio.
Chief Executive and Executive Chairman Francesco Gardin indicated that the development reinforces the company’s strategy of expanding its proprietary technologies aimed at enhancing the efficiency of cryptographic hashing hardware.
Commercial Opportunities Through Licensing
QBT believes the technology could generate interest among established ASIC manufacturers that are seeking to improve the performance and energy efficiency of next-generation Bitcoin mining equipment. The company plans to evaluate licensing agreements and other commercialization opportunities once the patent is formally granted.
To support these efforts, QBT is searching for semiconductor industry advisers who can help develop a strategy for monetizing the technology. However, the company cautioned that commercial discussions remain at an early stage and emphasized that there is no certainty regarding the timing, structure, or outcome of potential licensing agreements. It also noted that there is no assurance the patent will produce material revenue in the short term.
Gardin explained that, following payment of the required fees, the patent process is expected to conclude within approximately four to six weeks. He added that the company would continue to exercise caution until the USPTO formally issues the patent.
Efficiency Gains Could Benefit Large Mining Operations
The company believes its technology addresses one of the most challenging aspects of Bitcoin mining hardware, namely the hardware implementation of the SHA-256 algorithm. Gardin stated that significant advances in this area have historically been limited, making efficiency improvements particularly valuable for ASIC manufacturers.
Based on QBT’s internal estimates, the technology is expected to reduce the number of logic gates required in ASIC chips by between 5% and 8%. The company also estimates that energy consumption could decline by approximately 2% to 5%. Gardin indicated that while these percentage improvements may appear modest individually, they could deliver substantial cumulative savings across large-scale Bitcoin mining operations running thousands of specialized chips.
QBT estimates that its ASIC UltraBoost technology could reduce logic gate requirements by 5% to 8% and lower energy consumption by 2% to 5%, offering meaningful efficiency gains for industrial-scale Bitcoin miners.
The company also disclosed that it is already collaborating with an ASIC manufacturer as it advances commercialization efforts. In parallel, it is seeking additional semiconductor specialists to assist in structuring licensing and royalty agreements for the patented technology.
QBT is working with an ASIC manufacturer while developing a licensing strategy, positioning the technology for potential adoption by leading chip makers once the U.S. patent is formally granted.
Gardin further indicated that the market for the technology is clearly defined because prospective customers consist primarily of ASIC chip manufacturers, giving the company a well-established pathway toward commercial deployment if licensing discussions progress successfully.
