HashFast Technologies is a fabless semiconductor company specializing in extreme performance hashing ASICs.

Our mission is to deliver the absolute best technology for the network verification of digital currencies, specifically Bitcoin.

Our products are high-performance ASICs. Our first chip, the Golden Nonce (GN) microprocessor, is in the final stages of development. The GN chip will perform more than 400 Ghash per second and will ‘tape-out’ and be sent to manufacturing in August. Fabrication will take a little bit over two months, and the chips will ship to customers in October.

HashFast Technologies was founded in San Francisco in 2013 by Simon Barber and Eduardo de Castro
