May 7, 2020 University of Cambridge-affiliated group releases a novel Bitcoin hashrate tool.

The Cambridge Centre for Alternative Finance (CCAF), a team that is affiliated with the University of Cambridge’s Business School, has released a novel Bitcoin mining map that tracks the estimated geographical distribution of the Bitcoin network’s hashrate. The tool uses geo-location data of miners that connect to the BTC.com, Poolin, and ViaBTC mining pools which collectively account for 37% of Bitcoin’s hashrate, allowing it to map the geographic location of miners. The map currently shows that 65% of the Bitcoin’s hashrate comes from China but that this figure has decreased by approximately 10% since September 2019. The tool’s release comes just days away from the network’s much-anticipated halving event which is now set to occur earlier than originally expected due to a recent surge in hashrate that has increased the frequency of block-creation.
