Eight years ago today, someone bought two pizzas with bitcoins now worth $82 million
Why does Bitcoin consume electricity? Does energy usage increase with the number of transactions? Are Bitcoin miners polluters? Will Bitcoin miners pollute more or less in the future? Will cryptocurrencies become more efficient over time? Bitcoin consumes a sizable amount of electricity. The mere fact that Bitcoin uses this much electricity is not itself a problem, however.
This backgrounder will investigate those and other fundamental questions and direct readers to the most up-to-date research. Real world miners leverage expensive capital to dig impressive holes into the earth, to discover and extract marketable metals, minerals, and gems. They burn resources to get valuables. Bitcoin, aside from being an asset, is also a network of connected computers on the internet that, together, keep a record of all bitcoin transactions between the participants.
People trust Bitcoin as a store of value and medium of exchange in part because everyone can see this blockchain and see all the historical transactions including their own going back to the launch of the network in Mechanisms for generating consensus between several computers have been around since the s. Those old mechanisms would allow, for example, six data centers owned by IBM to stay in sync with each other, storing and updating some data that IBM cares about and wants redundantly stored on multiple machines.
Our IBM consensus example is closed ; the consensus rules only allow a set number of computers e. Older, closed consensus mechanisms stay in sync because identified participants take turns adding new data to the record, and they are secure because only identified participants are allowed to add data. This is where Bitcoin mining comes in. We have a longer post on the subject but here are the highlights in bullet form:. This mechanism makes fraud non-viable because miners suffer a cost to even be eligible in the lottery and they lose their eligibility if they try to submit invalid transactions.
To keep the lottery fair, the price of a ticket rises as people buy more of them; in other words miners have to compete. So if a lot of people are willing to spend computing effort to join the consensus, then the costs of participation will rise as the computing work you need to perform becomes more and more difficult. You might think this is all a bit of a rube goldberg machine. It is, indeed, complicated, but as of right now it is the most reliable mechanism in existence that allows a large set of unidentified computers to agree over shared data and, therefore, the best way to have peer-to-peer electronic cash.
This energy usage is anything but useless, it is securing data about transactions worth hundreds of billions of dollars. Unlike the energy used by a gold miner, it goes directly to providing a public good: online peer-to-peer payments infrastructure that anyone on Earth with a smartphone and internet connection can use.
This is incorrect. Digital signature validation uses a trivial amount of computing power. Why is there so much competition driving so much energy usage?
Bitcoins are expensive right now, and every 10 minutes one miner will get 6. This competition is healthy because it means that the effort spent securing the network scales automatically with the value of the transaction data on the blockchain—not the number of transactions. So the more value there is riding on the Bitcoin network because individuals value it more as reflected in the price , the more resources will be devoted to its security. One final thing about that competition.
It may get less fierce as time goes on. The reward of new bitcoins halves every four years until it goes effectively to zero. Miners will keep working because they can also collect fees that users of the network add to their transaction messages, but the total take-home payment for a winning miner will probably be less in the future than it is today even if the price of a Bitcoin continues to rise.
Smaller rewards will mean less computing power dedicated to winning and less electricity consumed. This is comparing apples and oranges, but investigating the question will still help us better understand the energy usage landscape. Unlike a Bitcoin transaction, a credit card transaction is not a settled payment. It is a payment authorization, merely the beginning of a convoluted dance between no fewer than five players the cardholder, the card issuing bank, the card network, the merchant acquiring bank, and the merchant.
In contrast, a Bitcoin transaction is settled the moment it hits the blockchain. And it need not travel through any clunky analog institutions along the way.
Each physical branch and ATM has a carbon footprint, as do the computer systems employed to reconcile accounts between banks, the fintech and credit card companies that facilitate consumer payments ultimately settled by banks, and the state and federal governments that regulate and ultimately enforce contracts for settlement.
Even a generally conservative energy estimate for the traditional financial system suggests that it uses as much as five times the energy usage of Bitcoin mining. Comparing bitcoin with gold is, again, not a like-for-like comparison but reasonable estimates suggest that bitcoin uses about half the energy of gold mining and recycling.
Energy use is not bad in and of itself. It is greenhouse gases that are bad, and Bitcoin miners already use more clean and renewable sources like geothermal and hydroelectric as a percentage of their total electricity consumption than the American household average.
Miners are mobile while electricity is not. Miners can easily locate wherever they have an internet connection and electricity.
Even though most power is generated locally we still lose a tremendous amount to transmission inefficiency e. Many types of power plants are also simply impossible to shut down without losses; the only way to stop a hydroelectric dam, for example, is to release excess water downstream and give up all that stored potential energy. Many Bitcoin miners choose to base their operations in parts of the world where significant green electricity is trapped because it makes mining more profitable: Iceland where there is geothermal power available, the Columbia River Valley in the US, and Sichuan province in China where there is abundant hydroelectric power.
Some miners are even using power generated by natural gas flaring. Whenever oil companies drill, some amount of gas will build up on site and need to be released. Companies can simply vent this into the atmosphere or they can burn it to produce electricity. Venting is much worse for the environment than burning because methane is, pound-for-pound, 25 times more powerful as a greenhouse gas than carbon dioxide.
Safely burning excess gas, however, requires costly infrastructure. Some Bitcoin miners are happy to foot the cost of safely burning flare gas because they can use the resultant power, on site, to mine bitcoins.
The mobility of mining is a double edged sword, however. If electricity is cheap in a region where coal-fired power plants predominate, Bitcoin miners will likely locate there as well. While some may wish to blame Bitcoin miners for that pollution, the fact is that Xinjiang electricity is cheap and pollutes because the Chinese government is paying people to burn coal. If Bitcoin mining becomes the dominant driver of energy consumption on the planet, then that could actually be a good thing for the environment.
Like Bitcoin miners, aluminum smelters chose to locate in places like Iceland so that they can take advantage of trapped green energy. Heavy industry can generally be based anywhere, and electrical costs tend to be a large percentage of their total costs. That means that heavy industry will base itself where costs are lower, and that will tend to be wherever electricity is affordable because its production is more efficient. Demand drives supply and thus rewards those who develop cheaper modes of electricity generation.
Lately that has roundly been a green affair. The cheapest electricity on the planet is now wind and solar energy. However, electricity costs may not always be top of mind for typical heavy industry. They may put up with expensive, dirty energy if other costs drive their decision-making. Industries also like to be where their customers are, where it is cheap to ship material inputs like metal, and where governments grant them subsidies in order to encourage industrial growth.
But electricity costs matter even more to a Bitcoin miner than typical heavy industry. Bitcoins are digital, they have only two inputs electricity and hardware and network latency is trivial as compared with a truck full of steel. If Bitcoin mining really does begin to consume vast quantities of the global electricity supply it will, it follows, spur massive growth in efficient electricity production— i. Got cheap green power?
Bitcoin could make building more of it well worth your time. We already learned that energy use will not increase alongside the number of Bitcoin transactions. Several efforts are underway to develop second-layer networks, or new open consensus mechanisms, that could allow for thousands and even millions of transactions per second. These scaling solutions take various approaches. Other developers are experimenting with new open consensus mechanisms that may enable massive scaling while simultaneously reducing energy usage.
Recall also that every lottery ticket has a cost measured in verifiable computations made. In a proof-of-stake consensus mechanism miners or validators still compete with each other to win a lottery, but tickets are provably costly because the participants prove that they own or have a stake in some amount of the cryptocurrency secured by the blockchain. It might be more appropriate to call these consensus participants stakers than miners but who knows which name will stick or if proof-of-stake will even be as secure and viable as proof-of-work.

BitMixer shuts down to ‘make Bitcoin ecosystem more clean’
First, know your memes. HODL began as a typo for the word "hold" on a bitcointalk. In December , bitcoin brought seasonal cheer to investors as its price gathered pace and broke records. The heady run-up in its price had bitcoin enthusiasts making wild forecasts about its price down the line. Three months later into , their prognoses were gloomier.
