Bitcoin Mining Turns Electricity Into Money
Bitcoin mining is the process of creating new bitcoin by solving puzzles. It consists of computing systems equipped with specialized chips competing to solve mathematical puzzles. The first bitcoin miner as these systems are called to solve the puzzle is rewarded with bitcoin. The mining process also confirms transactions on the cryptocurrency's network and makes them trustworthy.
For a short time after Bitcoin was launched, it was mined on desktop computers with regular central processing units CPUs. But the process was extremely slow. Now the cryptocurrency is generated using large mining pools spread across many geographies. Bitcoin miners aggregate mining systems that consume massive amounts of electricity to mine the cryptocurrency. In regions where electricity is generated using fossil fuels, bitcoin mining is considered detrimental to the environment. As a result, many bitcoin miners have moved operations to places with renewable sources of energy to reduce Bitcoin's impact on climate change.
Just as gold is mined from the earth using large implements and machines, bitcoin mining also uses big systems akin to data centers. These systems solve mathematical puzzles generated by Bitcoin's algorithm to produce new coins. By solving computational math problems, bitcoin miners also make the cryptocurrency's network trustworthy by verifying its transaction information. They verify 1 megabyte MB worth of transactions—the size of a single block. These transactions can theoretically be as small as one transaction but are more often several thousand depending on how much data each transaction stores.
The idea behind verifying Bitcoin transaction information is to prevent double-spending. With printed currencies, counterfeiting is always an issue. With digital currency, however, it's a different story. Digital information can be reproduced relatively easily, so with Bitcoin and other digital currencies, there is a risk that a spender can make a copy of their bitcoin and send it to another party while still holding onto the original. Bitcoin transactions are aggregated into blocks that are added to a database called blockchain.
Full nodes in Bitcoin's network maintain a record of the blockchain and verify transactions occurring on it. Bitcoin miners download the entire history of blockchain and assemble valid transactions into a block.
If the block of assembled transactions is accepted and verified by other miners, then the miner receives a block reward. Bitcoin successfully halved its mining reward—from The block reward is halved every , blocks or roughly every four years.
In , it was In , the reward amount declined to 25, and in , it became In Bitcoin's most recent halving event, the reward was changed to 6. Another incentive for bitcoin miners to participate in the process is transaction fees. In addition to rewards, miners also receive fees from any transactions contained in that block of transactions. As Bitcoin reaches its planned limit of 21 million expected around , miners will be rewarded with fees for processing transactions that network users will pay.
These fees ensure that miners still have the incentive to mine and keep the network going. The idea is that competition for these fees will cause them to remain low after halving events are finished. At the heart of bitcoin mining is a math puzzle that miners are supposed to solve in order to earn bitcoin rewards. The puzzle is called proof of work PoW , a reference to the computational work expended by miners to mine bitcoin.
Though it is often referred to as complex, the mining puzzle is actually fairly simple and can be described as guesswork. The miners in Bitcoin's network try to come up with a digit hexadecimal number, called a hash, that is less than or equal to a target hash in SHA, Bitcoin's PoW algorithm.
The systems that guess a number less than or equal to the hash are rewarded with bitcoin. Here's an example to explain the process.
Say I ask friends to guess a number between 1 and that I have thought of and written down on a piece of paper. If I am thinking of the number 19 and a friend comes up with 21, they lose because 21 is greater than But if someone guesses 16 and another friend guesses 18, then the latter wins because 18 is closer to 19 than In very simple terms, the bitcoin mining math puzzle is the same situation described above except with digit hexadecimal numbers and thousands of computing systems.
One of the terms you will often come across in bitcoin mining literature is mining difficulty. Mining difficulty refers to the difficulty of solving the math puzzle and generating bitcoin.
Mining difficulty influences the rate at which bitcoins are generated. Mining difficulty changes every 2, blocks or approximately every two weeks.
The succeeding difficulty level depends on how efficient miners were in the preceding cycle. It is also affected by the number of new miners that have joined Bitcoin's network because it increases the hash rate or the amount of computing power deployed to mine the cryptocurrency.
In and , as the price of bitcoin rose, more miners joined its network, and the average time to discover a block of transactions fell to nine minutes from 10 minutes.
But the opposite can also be true. That is, the more miners there are competing for a solution, the more difficult the problem will become. If computational power is taken off the network, the difficulty adjusts downward to make mining easier. The difficulty level for mining in August was more than 16 trillion. That is, the chances of a computer producing a hash below the target is 1 in 16 trillion. To put that in perspective, you are about 44, times more likely to win the Powerball jackpot with a single lottery ticket than you are to pick the correct hash on a single try.
At the end of the day, bitcoin mining is a business venture. Profits generated from its output—bitcoin—depend on the investment made into its inputs. There are three main costs of bitcoin mining:. The total costs for these three inputs should be less than the output—in this case, the bitcoin price—for miners to generate profits from their venture. Considering the skyrocketing price of bitcoin, the idea of minting your own cryptocurrency might sound like an attractive proposition.
El Salvador made Bitcoin legal tender on June 9, It is the first country to do so. The cryptocurrency can be used for any transaction where the business can accept it. The U. However, despite what Bitcoin proponents tell you, mining the cryptocurrency is not a hobby of any sort. It is an expensive venture with a high probability of failure.
As illustrated in the section on mining difficulty, there is no guarantee that you will earn bitcoin rewards even after spending considerable expenses and effort. Aggregating mining systems to run a small business that mines bitcoin might offer a way out.
However, even such businesses are at the mercy of the cryptocurrency's volatile prices. If the cryptocurrency's price crashes as it did in , then it becomes uneconomic to run bitcoin mining systems, and small miners will be forced to go out of business. The decline in the number of bitcoins awarded to miners every four years makes the activity even more unappealing. Given the considerable difficulty inherent in the economics of mining bitcoin, the activity is now dominated by large mining companies that have operations spanning multiple continents.
AntPool, the world's biggest bitcoin mining company, runs mining pools in many countries. Many bitcoin mining companies have also gone public, although their valuations are relatively modest. For most of Bitcoin's short history, its mining process has remained an energy-intensive process. In the decade after it was launched, bitcoin mining was concentrated in China, a country that relies on fossil fuels like coal to produce a majority of its electricity.
Not surprisingly, bitcoin mining's astronomical energy costs have drawn the attention of climate change activists who blame the activity for rising emissions. According to some estimates, the cryptocurrency's mining process consumes as much electricity as entire countries.
But bitcoin proponents have released studies that claim that the cryptocurrency is powered largely by renewable energy sources. You can read more about the debate here.
One thing to remember about these studies is that they are based on conjectures and self-reported data from mining pools.
For example, a Coinshares report from makes several assumptions regarding the power sources for miners included in their assessment of the bitcoin mining ecosystem. Two developments have contributed to the evolution and composition of bitcoin mining as it is today.
The first one is the manufacture of custom mining machines for bitcoin. Because bitcoin mining is essentially guesswork, arriving at the right answer before another miner has almost everything to do with how fast your computer can produce hashes. In the early days of Bitcoin, desktop computers with ordinary CPUs dominated bitcoin mining.
But they began taking a long time to discover transactions on the cryptocurrency's network as the algorithm's difficulty level increased with time.
According to some estimates, it would have taken "several thousand years on average" using CPUs to find a valid block at the early difficulty level. Over time, miners realized that graphics cards, also known as graphics processing units GPUs , were more effective and faster at mining.
But they consumed a lot of power for individual hardware systems that weren't really required for mining the cryptocurrency. Nowadays, miners use custom mining machines, called ASIC miners, that are equipped with specialized chips for faster and more efficient bitcoin mining. They cost anywhere from several hundred to tens of thousands of dollars. Today, bitcoin mining is so competitive that it can only be done profitably with the most up-to-date ASICs.
Even with the newest unit at your disposal, one computer is rarely enough to compete with mining pools—groups of miners who combine their computing power and split the mined bitcoin between them. Bitcoin forks have also influenced the makeup of the bitcoin miner network. Between 1 in 16 trillion odds, scaling difficulty levels, and the massive network of users verifying transactions, one block of transactions is verified roughly every 10 minutes.
But it's important to remember that 10 minutes is a goal, not a rule. The Bitcoin network can currently process just under four transactions per second, with transactions logged in the blockchain every 10 minutes.

There's also live online events, interactive content, certification prep materials, and more. Mining is the process by which new bitcoin is added to the money supply. Mining also serves to secure the bitcoin system against fraudulent transactions or transactions spending the same amount of bitcoin more than once, known as a double-spend. Miners provide processing power to the bitcoin network in exchange for the opportunity to be rewarded bitcoin. Miners validate new transactions and record them on the global ledger. Miners receive two types of rewards for mining: new coins created with each new block, and transaction fees from all the transactions included in the block.
