The map has now been updated after researchers from the Cambridge Bitcoin Electricity Consumption Index (CBECI) project stated that the website’s “Bitcoin Mining Map” had not been updated since April 2020.
The mining map’s current data indicates that coverage extends all the way to April 2021, and the estimate of China’s hashrate dominance is far lower than prior projections.
According to data from the University of Cambridge’s Cambridge Bitcoin Electricity Consumption Index (CBECI), China has significantly less hashrate supremacy than previously believed. On June 19, Bitcoin.com News discussed the difficulty of estimating how much hashrate is truly located in China.
The CBECI team revealed on its website that the Bitcoin Mining Map has not been updated since April 2020. Additionally, Bitcoin.com News was informed in December 2020 that the “CBECI map has not been updated in some time” by a University of Cambridge researcher.
That has changed, and the CBECI map now includes significantly more up-to-date information, at least until April 2021. As a result, the CBECI map will fail to account for the large exodus of Chinese bitcoin miners that occurred in April.
However, the newest CBECI map indicates that China’s hashrate supremacy was approximately 46% in April. This statistic is significantly lower than the previous estimate, which was 65 percent prior to the upgrade. According to CBECI’s “Evolution of country share” figures, the United States controls 16.8 percent of the market, while Kazakhstan controls 8.19 percent.
The researchers at the University of Cambridge analyse sample data from geolocated mining facilities and multiple bitcoin mining pools. Poolin, Viabtc, Btc.com, and Foundry are among the partners who contribute to the CBECI map.
In another graphic dedicated to similar figures, the CBECI map illustrates the “Evolution of Chinese provinces share.” Chinese provinces are dominated by Sichuan (16.4%), Xinjiang (54.4%), Yunnan (8.7%), Nei Mongol (3.7%), Gansu (1.3%), Zhejiang (0.2%), Beijing (4.8%), Qinghai (2.3%), and unknown places (8.1 percent ).
Apart from China, the United States, and Kazakhstan, the CBECI map indicates that the Russian Federation controls around 6.84 percent of the worldwide hashrate. This is followed by unknown regions, which account for 5.92 percent, Iran, which accounts for 4.64 percent, Malaysia, which accounts for 3.44 percent, Canada, which accounts for 3%, Germany, which accounts for 2.81 percent, and Ireland, which accounts for 2.27 percent.
After a lengthy period of inactivity, the CBECI research team notes that updates are now “scheduled on a monthly basis and are contingent upon data availability (generally with a one- to three-month delay).”
