Many people know that Bitcoin hashrate is concentrated in the hands of a group of large mining pools, 2 of which belong to the Chinese mining equipment manufacturer Bitmain.
More recently, the mining pools owned by the Chinese company Antpool and BTC.com controlled 42% of the hashrate, and therefore the cryptocurrency community was concerned about the present possibility of an attack of 51% .
Over the past six months, some changes have occurred in this segment. Antpool and BTC.com now control only 29% of the network's hashrate.
This change has been welcomed by the community, because the loss of market share by Bitmain positive impact on the decentralization of Bitcoins . And in recent years, the cryptocurrency industry is not the first significant change. For example, the BTCC and Bitfury pools throughout 2017 also consistently lost influence and now play a minor role.
The opposite situation is observed with a bitcoin fork – Bitcoin Cash cryptocurrency . According to the Coin Dance portal, at the moment, the Chinese pool BTC.TOP controls half of its hashrate. It accounts for 679 PH / s, while BTC.com controls 257 PH / s, ViaBTC – 215 PH / s, AntPool – 125 PH / s and Bitcoin.com – 187 PH / s.
According to an earlier study, 49% of Bitcoin Cash nodes are hosted on Alibaba servers. This information also does not add trust to cryptocurrency, which its followers call “real Bitcoin”.
According to the director of maintenance of Microsoft software identification unit Alex Simmons (Alex Simons), solution scalability blokcheyna that developers use Bitcoin Cash (increasing the block size) is more dangerous for decentralization, rather than a decision that developers use Bitcoin (Lightning Network).
