AsicBoost Press Release

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.”
