■ Now Supporting Bitcoin Gold Mining in Addition to Zcash
Cryptknocker is a mining software for cryptocurrencies that utilizes the Equihash algorithm. The software takes advantage of the technical knowledge of the certification authority business that GMO GlobalSign has cultivated, such as PKI (Public Key Infrastructure) encryption technology, and the expertise to speed up data processing during encryption.

Since the provisioning of Cryptknocker in September 2018, it supported only Zcash mining that utilizes the Equihash <200,9>. However, Bitcoin Gold mining using Equihash <144,5> is now also supported by the upgraded Cryptknocker.

■ Accomplishing the World’s Fastest Equihash Mining Software
With the high-speed encryption logic embedded, which is a part of GMO GlobalSign’s cultivated encryption technologies, Cryptknocker has achieved the world’s fastest hash rate³ among mining software that supports Equihash <200,9> and <144,5> algorithms.

40.74 Sol/s was recorded during the verification process of Bitcoin Gold that Cryptknocker now supports, enabling a maximum of 10% improvement in mining efficiency when compared with other existing software.

2 Update (Re-download) is required for existing users of Cryptknocker for Bitcoin Gold mining.
3 Hash rate is defined by the speed of mining. Whenever there is a transaction in cryptocurrency, the miners across the world conduct calculations for a few minutes. The number of calculations per second is referred to as the hash rate, and a unit of “sol/s” is used in the case of cryptocurrencies utilizing the Equihash algorithm.
