Bitcoin Mining
It consists of computer systems equipped with special chips that compete with each other in solving mathematical puzzles. The first bitcoin miner (as these systems are called) to solve the puzzle will be rewarded with bitcoins. The mining process also confirms transactions in the cryptocurrency network and makes it reliable.
Shortly after launching Bitcoin, it was mined into desktop computers with standard central processing units (CPUs). But the process is very slow. Cryptocurrency is now created using large mining pools scattered over many areas. Bitcoin miners are developing mining systems that consume large amounts of electricity to mine cryptocurrencies.
In areas where electricity is generated from fossil fuels, bitcoin mining is considered pollution. As a result, many bitcoin miners are moving to renewable energy sites to reduce the impact of bitcoin on climate change.
KEY TAKEAWAYS- Bitcoin mining is the process of creating new bitcoins by solving a mathematical puzzle.
- Bitcoin mining is necessary to maintain the global trading base on which Bitcoin is built.
- In recent years, miners have become very sophisticated, using modern hardware to speed up their mining operations.
- Bitcoin mining has generated controversy because it is not considered environmentally friendly.
Just like mining gold from the ground using large equipment and machinery, bitcoin mining uses large systems such as data centers. These systems solve mathematical puzzles created by the Bitcoin algorithm to create a new currency.
Bitcoin miners also rely on the cryptocurrency network to solve math problems and verify transaction information. They perform transactions up to 1 megabyte (MB), which is the size of a block.2 In theory, these transactions could be as small as one transaction, but are usually in the tens of thousands, depending on the amount of data. each transaction stores. . The idea behind verifying bitcoin trading information is to avoid double-spending. When it comes to printed money, counterfeiting is always a problem. But usually, if you spend $ 20 at a store, that bill is in the hands of the seller. But with digital currencies, the situation is different.
Digital information is relatively easy to copy, so with bitcoin and other digital currencies, there is a risk that the donor will make a copy of their bitcoin and send it somewhere while keeping the original3.
Bitcoin transactions are grouped into blocks, which are added to a database called a blockchain. An entire node in the Bitcoin network store files on the blockchain and verify the transactions taking place there. Bitcoin miners download the entire history from the blockchain and combine current transactions into one block. If a block is accepted and verified by other miners, the miner will receive a block reward.
The block reward is divided every 210,000 blocks (or approximately every four years). In 2009 he turned 50 years old. In 2013, the number of awards was reduced to 25, and in 2016 it was 12.5. In the last split of bitcoin, the reward rose to 6.25.5.
Transaction fees are another incentive for Bitcoin miners to participate. In addition to the reward, miners also receive a commission for all transactions included in this blockchain. Once Bitcoin has reached the predicted limit of 21 million (expected around 2140), miners will be rewarded with transaction fees that network users must pay. These costs ensure that miners have an incentive to work and keep the network running. The idea is that competition for these fees will keep them low after half of the events are completed.
Math puzzle Mining What is bitcoin?
At the heart of bitcoin mining is a mathematical puzzle that miners must solve in order to be rewarded with bitcoins. The puzzle is called Proof of Work (PoW), a reference to how much miners spend on mining bitcoins. Although the mining puzzle is often referred to as difficult, it is actually quite simple and can be called divination.
Miners in the Bitcoin network are trying to find a 64-digit hexadecimal number called fragmentation that is less than or equal to the fragmentation target in SHA256, Bitcoin’s PoW algorithm. Miner systems use large amounts of raw power in the form of several computing units stacked on top of each other and initiate hashes at different rates - mega hashes per second (MH/s), gigahashes per second ( GH/s) o terahashes per second. (TH/s) - Guess all possible combinations of 64 numbers, depending on the unit, until they are solved. Systems that guess a number less than or equal to the hash will be rewarded with bitcoins.
Here is an example that illustrates the process. Let’s say you ask your friends to guess a number from 1 to 100 that you will write on a piece of paper. Your friends don't have to guess the exact number. You must be the first to guess a number less than or equal to your own number.
If you think of the number 19 and you find 21 friends, it will be defeated because 21 is greater than 19. The mining puzzle is the same situation as above, except for the 64-digit hexadecimal numbers and thousands. -thousands of computer systems.
What is the difficulty of mining?
One of the terms you’ll find in the bitcoin mining literature is the mining difficulty. Mining difficulty refers to the difficulty in solving a math puzzle and generating bitcoins. The difficulty of mining affects the production rate of bitcoins.
The difficulty level changes every 2016 block or approximately every two weeks. The next level of difficulty depends on the efficiency of the miners in the previous cycle. It is also affected by the number of new miners joining the Bitcoin network as it increases the rate of fragmentation or the amount of computing power used to mine the cryptocurrency. In 2013 and 2014, as the price of Bitcoin rose, more miners joined the network and the average blockchain mining time dropped from 10 minutes to 9 minutes.
But the opposite can also be true. In other words, the more the miner competes for a solution, the more difficult the problem becomes. When computing power is removed from the network, the complexity is reduced to make it easier to remove.
In March 2022, mining poverty was 27.55 trillion. Thus, the probability that the computer will generate a hash below the target is 1 in 27.55 trillion. To put this in perspective, your chances of winning the Powerball jackpot on a single ticket are approximately 91,655 times greater than hitting the right hit on a trial67.
What are the financial elements of bitcoin mining?
After all, bitcoin mining is a commercial business. The income from its production - Bitcoin - depends on investing in its inputs.
Bitcoin mining has three main costs:
Electricity: This is the energy that powers mining systems 24/7. Maybe there's a big bill. The costs can be quite high because the process consumes more electricity like in some countries.
Mining Systems: Contrary to popular belief, desktop computers, and consumer gaming systems are not suitable or efficient for bitcoin mining. This process can heat up these systems and cause bandwidth issues on your home network. Application-Specific Integrated Chip (ASIC) systems, machines specifically designed for bitcoin mining, are the most important infrastructure investment for bitcoin miners. The price range for these machines can be from $ 4,000 to $ 12,000. Even at this high cost, an ASIC system generates less than a bitcoin. Bitcoin miners deploy thousands of ASIC systems in mining pools 24/7 to generate the 64-digit hexadecimal number needed to solve a complex puzzle.
Network Infrastructure: Network speed is not important in the bitcoin mining process. However, it is important that the Internet connection is available 24 hours a day, 7 days a week. The connection should also be slow due to nearby mining pools. Private networks reduce external dependency and minimize latency. An offline connection does not necessarily interfere with the process synchronization process. However, once the connection is re-established, this can make the process lengthy and possibly easy to have an error.
The total value of these three inputs must be less than the output — in this case, the price of bitcoin — in order for miners to earn from their activities. Given the rising price of bitcoin, the idea of hacking your own cryptocurrency may seem tempting.
However, despite what bitcoin fans will tell you, cryptocurrency mining is not a hobby. This is an expensive task with a high probability of failure. As explained in the mining section, there is no guarantee that you will be rewarded with bitcoin, even if you pay a substantial cost and effort. The solution could be to install mining systems to run a small bitcoin mining business. But even these companies rely on cryptocurrency price volatility. If the price of cryptocurrencies drops, such as in 2018, bitcoin mining systems will be unprofitable to operate, and small miners will be forced to shut down9. Decreasing the number of bitcoin mines every four years makes the job more attractive.
Due to the serious challenges inherent in the Bitcoin mining economy, the business is now dominated by large mining companies operating on many continents. AntPool, the largest bitcoin mining company in the world, operates mining pools in many countries. Many bitcoin mining companies also went public, even though their value was relatively low. Bitcoin Energy Consumption
For most of Bitcoin’s short history, the mining process has remained energy-intensive. In the decade since it began, bitcoin mining has been concentrated in China, a country that uses fossil fuels like coal to generate electricity. Not surprisingly, the astronomical energy cost of bitcoin mining has caught the attention of climate change activists who blame activity for rising emissions. According to some estimates, the cryptocurrency mining process consumes as much electricity as any country8. But Bitcoin proponents have published studies saying the cryptocurrency is largely powered by renewable energy sources.
One thing to note about these studies is that they are based on suspicion and data provided by researchers of the mineral deposit itself. For example, the 2019 Coinshares report makes some assumptions about the energy resources of miners included in the analysis of the bitcoin mining ecosystem
History of bitcoin mining
Two events contributed to the development and synthesis of bitcoin mining in its current form. The first is the construction of special machines for mining bitcoins. Since bitcoin mining is essentially speculation, finding the right answer before another miner is more dependent on how quickly your computer can generate hashes. In the early days of bitcoin, desktop computers with common processors dominated bitcoin mining. However, as the complexity of the algorithm increased over time, it took a long time to determine transactions in the cryptocurrency network. By some estimates, in early 2015 it will take processors “an average of hundreds of thousands of years” to find the right block.11
Over time, miners have realized that graphics cards, also known as graphics processing units (GPUs), provide better and faster mining. But they use a lot of power for separate hardware systems, which isn’t really necessary for cryptocurrency mining. Field Programmable Gate Arrays (FPGAs), a type of GPU, are an improvement, but they have the same disadvantages as GPUs.
Today, miners use special mining machines called ASIC miners, equipped with special chips, to mine bitcoins faster and more efficiently. They cost anywhere from a few hundred to tens of thousands of dollars. Bitcoin mining is so competitive today that it can only work with the latest ASICs. On desktops, GPUs, or older ASICs, the amount of power consumption exceeds the revenue generated. Even with the latest hardware, you have available, a computer is rare enough to compete with mining pools-groups of miners who use their computing power to share bitcoin mines.
Bitcoin forks have also affected the structure of the Bitcoin mining network. Between 1 in 16 trillion possibilities, increasing levels of complexity, and an extensive network of users verifying transactions, a block of transactions is verified almost every 10 minutes12. However, it is 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 recorded on the blockchain every 10 minutes.13 In comparison, Visa can process approximately 65,000 transactions per second. 14 However, as the number of Bitcoin network users grows, the number of transactions per 10 minutes will reach 10. exceed the number of transactions per minute. From now on, unless changes are made to the Bitcoin protocol, transaction delays will start to accelerate and increase.
This problem at the heart of the Bitcoin protocol is known as scaling. While Bitcoin miners generally agree that something needs to be done to deal with the escalation, there is no consensus on how to do it. Two main solutions are proposed to solve the update problem. The developers have proposed creating an “off-chain” second layer of bitcoin that will speed up transactions that can be verified on the blockchain, or increase the number of transactions that can be stored by each block. With fewer data per block, the first solution will make transactions faster and cheaper for miners. The second will focus on scaling, increasing the block size every 10 minutes, which will allow more information to be processed.
In July 2017, bitcoin miners and mining companies, which cost approximately 80-90% of the network’s computing power, voted to combine a program that would reduce the amount of data needed to verify each block.
The program that the miners voted to add to the Bitcoin protocol is called Segregated Witness or SegWit. The term is a combination of the words “segregated”, “separated”, and “witness”, which refers to signatures on bitcoin transactions. So a split witness means splitting the signatures of a block’s transactions and adding them as an extended block. While adding a program to the Bitcoin protocol may not seem like a big deal, it is estimated that signature data makes up 65% of the data processed in each block of a transaction.
Less than a month later, in August 2017, a group of miners and developers launched a hard fork that allows the Bitcoin network to create a new currency with the same codebase as Bitcoin. Although this group agreed that a scaling solution was needed, they were concerned that the use of SegWit technology would not completely solve the scaling problem.
Instead, they chose the second solution to increase the number of transactions that each block could store. The resulting currency, called Bitcoin Cash, increased the block size to 8MB to speed up the verification process and return approximately 2 million transactions per day.
