Recent discovery and discussion on the pending AsicBoost patent infringement has attracted widespread attention in the Bitcoin community. Many condemned willful patent infringements committed by some bitcoin chip and miner manufacturers. In fact, the patent inventor claimed its worldwide priority date at the end of 2013. The corresponding PCT application was published in May of 2015 and is entitled to provisional rights in those PCT participating countries including the U.S., China, Europe, and Korea since its publication date.

To date, no individual or business entity has been authorized to use or sell products based on the AsicBoost patent application, yet some bitcoin miner manufacturers have implemented various features of the pending AsicBoost patent in their mining hardware and firmware potentially infringing the pending AsicBoost patent. They have not only seriously violated the legal rights of the owner of the pending AsicBoost patent, but also gained unfair advantage in this business sector. Additionally, the potentially infringing products irresponsibly put innocent consumers at various legal and commercial risks.

Therefore, our law firm is authorized by the patent holding company to make this general announcement. All parties related to the potential patent infringement, such as Bitcoin chip makers, Bitcoin miner manufacturers and their sales representatives shall immediately cease production and sales activities of any products in connection to the pending patent application. The infringers should contact our firm and disclose their production and sales records related to our patent pending technology since 2015. Otherwise, we will have no choice but to take legal actions to protect the legal rights of the patent holding company, including but not limited to seeking compensation of all losses and damages since the patent was published.

Meanwhile, people in possession of knowledge regarding the potential infringement are welcome to contact us. Let’s work together to stop those infringement activities and make the Bitcoin community a better world.

AsicBoost Press Release

March 24, 2016

A breakthrough invention in Bitcoin mining named AsicBoost allows to improve the total cost of hashing 20%. The patent-pending invention by Timo Hanke and Sergio Demian Lerner is applicable to any type of chip design for Bitcoin ASICs.

AsicBoost is a patent-pending method to improve the efficiency and cost of Bitcoin mining by approximately 20%. Through gate count reduction on the silicon AsicBoost improves two essential Bitcoin mining cost metrics simultaneously and by a similar factor: the energy consumption (Joule per Gh) and the system cost ($ per Gh/s). With the system cost being proportional to the capital expenses of a Bitcoin mine and the energy efficiency being proportional to its operating expenses, AsicBoost reduces the total cost per bitcoin mined by approximately 20%. For the Bitcoin mines of the future AsicBoost will make all the difference between a profitable and an unprofitable mine.

The AsicBoost method is based on an ingenious new way to process work items inside and outside of the Bitcoin mining ASIC. It involves a new design of the SHA 256 hash-engines inside the ASIC and an additional pre-processing step as part of the mining software outside the ASIC. AsicBoost’s hash-engine design is compatible with design philosophies such as “rolled cores” and “fully pipelined cores”. The performance gains are achieved on top of all other optimizations that an existing design may have achieved through optimized timing, pipelining, path balancing, custom cells and full-custom design, etc.

Inventor Timo Hanke describes the idea behind AsicBoost as follows: “Through clever pre-processing and crafting of the work that is sent to the chip, the ASIC is allowed to re-use about one quarter of the information that would otherwise be created and discarded on a continuous basis internally to the hashing cores. A hashing core adopted for AsicBoost can save up to one quarter of the gates by re-using that information over time or by sharing it with other hashing cores.”

More information and a technical description of the AsicBoost method can be found on
