Quantum Blockchain Technologies Plc(“QBT” or “the Company”)
NDA signed to provide QBT with
5nm Technology for Proprietary Bitcoin mining ASIC
The board of Quantum Blockchain Technologies (AIM: QBT) is pleased to announce that it has made the key decision to focus on the development of the more efficient 5nm Application-Specific Integrated Circuit (“ASIC”), rather than a 7nm ASIC (as announced on 5 November 2021), to use as its proprietary Bitcoin mining tool.
This decision was taken following a recent market announcement by a leading international Bitcoin mining equipment manufacturer that it will use 5nm ASICs for its the next generation of Bitcoin miners, which it expects to release in the second half of 2022. Accordingly, QBT has updated its development programme for the prototyping and industrial manufacturing of its proprietary Bitcoin mining, to use the 5nm ASIC.
Based on the Company’s internal projections, it believes that its previously planned optimised 7nm ASIC, would run at the same speed as the proposed 5nm ASIC, as announced by the above-mentioned Bitcoin miner manufacturer; this calculation is assuming the same number of ASICs will be used in the next mining model, as the above-mentioned miner currently applies to its existing model.
The rationale to move from a 7nm to 5nm, is because the estimated speed of QBT’s proprietary Bitcoin mining ASIC is expected to be at least twice as fast as the leading international Bitcoin miner manufacturer, before taking into account the optimisations of a second patent under development, which are yet to be factored in.
The Company will, therefore, move directly to developing a 5nm ASIC prototype, although it will still consider a phase of testing, as an intermediate step, on the 12nm ASIC, as announced on 5 November 2021.
A Non-Disclosure Agreement (“NDA”) has been signed with an international research & development organisation, which is active in the field of nanoelectronics, and which will give the Company access to one of the few 5nm semiconductor fabrication plants currently operational in the world.
The Company recognises that this significant step change, from 7nm to 5nm will, with regards to industrial production be significantly more expensive than its original strategy. However, as a first step, the initial phase of prototype testing of a 5nm ASIC will not cost the Company much more than the same process for a 7nm ASIC.
Assuming that the second patent application is filed by the Company’s cryptography expert by the end of February 2022, a first 5nm prototype, which would include all the improvements of both QBT’s first (ASIC UltraBoost) and second patent application, could be ready for manufacture in Q3 2022.
