An Honest Explanation of Price, Hashrate & Bitcoin Mining Network Dynamics
The Bitcoin Energy Consumption Index provides the latest estimate of the total energy consumption of the Bitcoin network. Annualized Total Bitcoin Footprints. Single Bitcoin Transaction Footprints. Criticism and potential validation of the estimate is discussed here. The latter has been removed per October 1, Moreover, the energy used is primarily sourced from fossil fuels.
The Bitcoin Energy Consumption Index was created to provide insight into these amounts, and raise awareness on the unsustainability of the proof-of-work algorithm. A separate index was created for Ethereum, which can be found here. The only thing miners have to trust is the code that runs Bitcoin.
The code includes several rules to validate new transactions. For example, a transaction can only be valid if the sender actually owns the sent amount. Every miner individually confirms whether transactions adhere to these rules, eliminating the need to trust other miners. The trick is to get all miners to agree on the same history of transactions.
Every miner in the network is constantly tasked with preparing the next batch of transactions for the blockchain. Only one of these blocks will be randomly selected to become the latest block on the chain.
In proof-of-work, the next block comes from the first miner that produces a valid one. This is easier said than done, as the Bitcoin protocol makes it very difficult for miners to do so. In fact, the difficulty is regularly adjusted by the protocol to ensure that all miners in the network will only produce one valid block every 10 minutes on average. Once one of the miners finally manages to produce a valid block, it will inform the rest of the network.
Other miners will accept this block once they confirm it adheres to all rules, and then discard whatever block they had been working on themselves.
The lucky miner gets rewarded with a fixed amount of coins, along with the transaction fees belonging to the processed transactions in the new block. The cycle then starts again. For this reason, mining is sometimes compared to a lottery where you can pick your own numbers.
This will typically be expressed in Gigahash per second 1 billion hashes per second. The continuous block mining cycle incentivizes people all over the world to mine Bitcoin. As mining can provide a solid stream of revenue, people are very willing to run power-hungry machines to get a piece of it. Over the years this has caused the total energy consumption of the Bitcoin network to grow to epic proportions, as the price of the currency reached new highs. The entire Bitcoin network now consumes more energy than a number of countries.
If Bitcoin was a country, it would rank as shown below. The result is shown hereafter. Thinking about how to reduce CO2 emissions from a widespread Bitcoin implementation. Determining the exact carbon impact of the Bitcoin network has been a challenge for years. Not only does one need to know the power requirement of the Bitcoin network, but one also need to know where this power is coming from.
The location of miners is a key ingredient to know how dirty or how clean the power is that they are using. Initially the only information available to this end was the common belief that the majority of miners were located in China. Since we know the average emission factor of the Chinese grid around grams of carbon dioxide equivalent per kilowatt-hour , this can be used for a very rough approximation of the carbon intensity of the power used for Bitcoin mining.
This number can subsequently be applied to a power consumption estimate of the Bitcoin network to determine its carbon footprint. In this study, they identified facilities representing roughly half of the entire Bitcoin hash rate, with a total lower bound consumption of megawatts. Chinese mining facilities were responsible for about half of this, with a lower bound consumption of megawatts.
The table below features a breakdown of the energy consumption of the mining facilities surveyed by Hileman and Rauchs. This number is currently applied to determine the carbon footprint of the Bitcoin network based on the Bitcoin Energy Consumption Index.
One can argue that specific locations in the listed countries may offer less carbon intense power. In Bitcoin company Coinshares suggested that the majority of Chinese mining facilities were located in Sichuan province, using cheap hydropower for mining Bitcoin. The main challenge here is that the production of hydropower or renewable energy in general is far from constant.
In Sichuan specifically the average power generation capacity during the wet season is three times that of the dry season. Because of these fluctuations in hydroelectricity generation, Bitcoin miners can only make use of cheap hydropower for a limited amount of time. Using a similar approach, Cambridge in provided a more detailed insight into the localization of Bitcoin miners over time.
Charting this data, and adding colors based on the carbon intensity of the respective power grids, we can reveal significant mining activity in highly polluting regions of the world during the Chinese dry season as shown below.
On an annual basis, the average contribution of renewable energy sources therefore remains low. An update on the Cambridge mining map in showed that the share of the network in these areas was already declining prior to the Chinese ban on cryptocurrency mining. It is important to realize that, while renewables are an intermittent source of energy, Bitcoin miners have a constant energy requirement. 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.
Because of this, Bitcoin miners increase the baseload demand on a grid. In the latter case Bitcoin miners have historically ended up using fossil fuel based power which is generally a more steady source of energy. With climate change pushing the volatility of hydropower production in places like Sichuan, this is unlikely to get any better in the future. To put the energy consumed by the Bitcoin network into perspective we can compare it to another payment system like VISA for example.
According to VISA, the company consumed a total amount of , Gigajoules of energy from various sources globally for all its operations. We also know VISA processed With the help of these numbers, it is possible to compare both networks and show that Bitcoin is extremely more energy intensive per transaction than VISA. The carbon footprint per VISA transaction is only 0. But even a comparison with the average non-cash transaction in the regular financial system still reveals that an average Bitcoin transaction requires several thousands of times more energy.
As a new block will be generated only once every 10 minutes on average, this data limit prevents the network from handling more than 7 transactions per second.
In the most optimistic scenario Bitcoin could therefore theoretically handle around million transactions annually. Meanwhile, the global financial system is handling more than billion digital payments per year and a payment provider like VISA can handle over 65, per second if needed. This is less than the total number of electronic payments processed in a country like Hungary more than million per year , not even considering that cash still makes up for two thirds of all payment transactions here.
Because of this, the Bitcoin network can consume several times as much electrical energy as the entire country of Hungary which consumes 43 TWh annually. Proponents of the digital currency argue that so-called second layer solutions like the Lightning Network will help scaling Bitcoin, while dismissing that it is practically impossible to make such a solution work on a substantial scale.
In order to move any amount of funds into the Lightning Network in the first place, a funding transaction on the main network is still required. It would take the Bitcoin network 35 years to process a single funding transaction for all 7.
The obvious problem with this is that it merely reinvents the system we already have in place. Hence we can also compare Bitcoin mining to gold mining instead. Every year, around 3, tonnes of gold are mined, with a total related emissions amounting to 81 million metric tonnes of CO2.
When comparing this to the carbon intensity of mining Bitcoins, we can observe that the latter exceeds that of mining real gold see below. Likewise, the comparison is also flawed because we can stop mining for real gold, whereas Bitcoin would simply stop existing without active mining. More energy efficient algorithms, like proof-of-stake, have been in development over recent years.
In proof-of-stake coin owners create blocks rather than miners, thus not requiring power hungry machines that produce as many hashes per second as possible. Because of this, the energy consumption of proof-of-stake is negligible compared to proof-of-work. Bitcoin could potentially switch to such an consensus algorithm, which would significantly improve environmental sustainability. It is estimated that a switch to proof-of-stake could save 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.
This arbitrary approach has therefore led to a wide set of energy consumption estimates that strongly deviate from one another, sometimes with a disregard to the economic consequences of the chosen parameters.
The Bitcoin Energy Consumption Index therefore proposes to turn the problem around, and approach energy consumption from an economic perspective. The index is built on the premise that miner income and costs are related. Since electricity costs are a major component of the ongoing costs, it follows that the total electricity consumption of the Bitcoin network must be related to miner income as well.
To put it simply, the higher mining revenues, the more energy-hungry machines can be supported. 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 calculator that allows for testing different assumptions has been made available here. The chosen assumptions have been chosen in such a way that they can be considered to be both intuitive and conservative, based on information of actual mining operations.
In the end, the goal of the Index is not to produce a perfect estimate, but to produce an economically credible day-to-day estimate that is more accurate and robust than an estimate based on the efficiency of a selection of mining machines.

If China’s interfering with hash rate and mining pools, then Bitcoin just proved its resilience
It is impossible to usher in a new year without assessing the status of cryptocurrency favourite bitcoin BTC. Bitcoin has started the year with a bang on news of its hash rate reaching an all-time high as it celebrated its 13th birthday on 3 January. The hash rate refers to the total combined computational power used by miners and to mint new bitcoin and conduct new transactions. Basically, the higher the hash rate the more secure the network becomes as it requires more computing power to attack it.
Why China Is Cracking Down on Bitcoin Mining and What It Could Mean for Other Countries
As the price climbs, so does the Bitcoin network's hash rate -- or the computing power being used to verify transactions and mine new Bitcoin. For a proof-of-work cryptocurrency like Bitcoin, hashrate is used to measure the total computational power being used to process transactions and mine new coins. Each transaction in a cryptocurrency network needs to be added to the digital ledger, or blockchain. But before data on a transaction is recorded on the blockchain, miners the powerful computers used to manage the network need to guess an alphanumeric code called a hash representing the data from the transaction. Each hash is random and complex, so it takes significant energy to power these computers. Once miners solve the hash, a new block is added to the blockchain, and a new unit of digital currency is rewarded to the successful miner. Besides Bitcoin , Litecoin , Dogecoin , and Monero all use the proof-of-work method to verify transactions and manage the blockchain network. Ethereum also used proof of work before switching to proof of stake. A proof-of-stake model does not use a hashing algorithm to manage a cryptocurrency network, instead awarding computing power and ability to earn rewards based on how much of the crypto a miner owns. For those cryptos that do use a hash algorithm, why is hashrate so important?
How Is the Hash Rate of Your Cryptocurrency Calculated?
Bitcoin mining is the process by which new bitcoins are entered into circulation. It is also the way the network confirms new transactions and is a critical component of the blockchain ledger's maintenance and development. The first computer to find the solution to the problem receives the next block of bitcoins and the process begins again. Cryptocurrency mining is painstaking, costly, and only sporadically rewarding. Nonetheless, mining has a magnetic appeal for many investors who are interested in cryptocurrency because of the fact that miners receive rewards for their work with crypto tokens.
Bitcoin Network Hash Rate
Bitcoin mining is a process that verifies transactions on the blockchain ledger, while also bringing new bitcoins into circulation. To be successful at this, cryptominers require vast amounts of computing power, meaning electricity becomes one of their most significant costs. This pushes them to locate wherever electricity is cheapest. For years, China was the optimal location—the country has an abundance of cheap, coal-powered electricity. However, in September , the Chinese government issued a blanket ban on all crypto activities. The University of Cambridge maintains various datasets on the Bitcoin blockchain, including power consumption and hash rate.
BTC Hash Rate Gains in 2022
The factors mentioned are temporary and we predict that, once the market picks up, BTC [Bitcoin] mining will gain its difficulty levels that represent higher ROI [return on investment] for miners in the ecosystem. With numerous tokens being launched for each of these use cases, it is not surprising that ETH has surpassed BTC in terms of active addresses. Times Internet Limited. All rights reserved.
