in Gigahash per second (1 billion hashes per second). In Sichuan specifically the average power generation capacity during the wet season is three times that of the dry season. New sets of transactions (blocks) are added to Bitcoins blockchain roughly every 10 minutes by so-called miners. Every miner individually confirms whether transactions adhere to these rules, eliminating the need to trust other miners. 1 China 111.60 711 2 Georgia.80 231 3 US.60 489 4 Canada.70 158 5 Sweden.30 13 6 Iceland.10 0 7 Estonia.90 793 8 Total 233 100.00 475 One can argue that specific. The carbon emission factor of purchased electricity in Sichuan therefore ranges from 265 to 579 gCO2/kWh. How the Bitcoin Energy Consumption Index uses miner income to arrive at an energy consumption estimate is explained in detail here (also in peer-reviewed academic literature here and summarized in the following infographic: Note that one may reach different conclusions on applying different assumptions (a. The model predicts that miners will ultimately spend 60 of their revenues on electricity. If Bitcoin was a country, it would rank as shown below.

This is nowhere near the emission factor of a grid like the one in Sweden, which is really fuelled mostly by nuclear and hydroelectric power. At the same time, Bitcoin miners do have a constant energy requirement. Ever since its inception Bitcoins trust-minimizing consensus has been enabled by its proof-of-work algorithm. On October 31st, 2008, an individual or group of individuals operating under the pseudonym "Satoshi Nakamoto" published the Bitcoin Whitepaper and described it as: "a purely peer-to-peer version of electronic cash would allow online payments to be sent directly from one party to another without. Comparing Bitcoins energy consumption to other payment systems To put the energy consumed by the Bitcoin network into perspective we can compare it to another payment system like visa for example. The carbon emission factor of the Swedish grid is 13 gCO2/kWh. The Bitcoin Energy Consumption Index therefore proposes to turn the problem around, and approach energy consumption from an economic perspective. Energy consumption model and key assumptions Even though the total network hashrate can easily be calculated, it is impossible to tell what this means in terms of energy consumption as there is no central register with all active machines (and their exact power consumption). Another correction would be required for the simple fact that Bitmain (with a claimed market share of around 70 ) is not the sole producer of Bitcoin mining machines, and for the fact that they were also selling less efficient (but more stable) Bitcoin mining. A Bitcoin asic miner will, once turned on, not be switched off until it either breaks down or becomes unable to mine Bitcoin at a profit.
