Bitcoin mining

Bitcoin mining is done on very powerful computers that solve very complex mathematical problems. The work required for a computer to solve any of these problems is the equivalent of a miner trying to extract gold from the ground. Today, the probability that a computer will solve any of these math problems is about 1 in 13 billion, but we’ll talk about that later.

The result of bitcoin mining is twofold:

  1. First of all, when computers solve these complex mathematical problems on the Bitcoin network, they produce new bitcoins, much like mining does when it extracts gold or some other metal.
  2. Second, by solving these math problems, bitcoin miners make the Bitcoin payment network reliable and safe by verifying transaction information.

For those new to the cryptocurrency world, a lot of what we’ve been saying surely doesn’t make a lot of sense. To explain in more detail how bitcoin mining works, let’s start with a process a little closer to us: the regulation of print money.

How is Bitcoin different from traditional currencies?

Consumers tend to trust printed currencies (fiat currencies), at least in modern countries, because they are backed by a central bank, like the Federal Reserve in the United States, the European Central Bank in the European Union, and the Bank of England in the United Kingdom.

Even digital payment systems with fiat currencies are backed by a central authority. When a person makes an online purchase with their debit or credit card, for example, that transaction is processed by a payment processor such as Mastercard or Visa. In addition to recording their transaction history, these companies verify that the transactions are not fraudulent, which is one of the reasons why a person’s debit or credit card can be suspended while traveling. .

Cryptocurrencies, on the other hand, are not regulated by a central authority. Bitcoin is supported by millions of computers around the world called “nodes”. This computer network performs the same function as the Federal Reserve, Visa and Mastercard, but with a few essential differences. Nodes store information about past transactions and help verify their authenticity. However, unlike these central authorities, uk trading nodes are spread all over the world and record transaction data in a public list accessible to everyone.

What is bitcoin mining?

Transactions in physical stores and on the Internet are documented by banks, point-of-sale systems and physical receipts. Bitcoin miners achieve the same effect without these institutions by grouping transactions into “blocks” and adding them to a public ledger called “blockchain”. Nodes keep records of these blocks so that they can be verified in the future.

When bitcoin miners add a new block of transactions to the blockchain, part of their job is to verify that those transactions are correct. In particular, online trading uk ensure that cryptocurrencies are not duplicated, a unique feature of digital coins called “double spending”. With printed currencies, duplication of currency is not a problem. When a person spends $ 50 in a store, that money is already in the hands of the employee. But with digital currency, it’s a different story.

Digital information can be reproduced relatively easily, so with bitcoins and other digital coins, there is a risk that a user could make a copy of their bitcoins to send them elsewhere while keeping the original bitcoins. Let’s go back to printed change for a moment and say someone tried to duplicate your $ 50 bill to spend on both the original and the counterfeit. If an employee knows that customers are duplicating money, they can just look at the serial numbers on the tickets. If the numbers turn out to be the same, the employee will know that the money has been duplicated. This analogy is similar to what a bitcoin miner does when they verify new transactions.

Reward for minors

However, with up to 500,000 buys and sells in a single day, verifying each of these transactions can be a lot of work for miners, which is another key difference between bitcoin miners and the Federal Reserve, Mastercard. or Visa. As compensation for their efforts, miners are given bitcoin every time they add a new block of transactions to the chain. The amount of new bitcoin released with each block mined is called the “block reward”. The overall reward is halved every 210,000 blocks, or roughly every 4 years. It was 25 in 2012, 12.5 in 2016, and it will be 6.25 in 2020.

At this rate, the total number of bitcoins in circulation will approach a limit of 21 million, making the currency rarer and more valuable over time, but also more expensive for miners.

How does Bitcoin mining work?

In order for bitcoin miners to actually earn bitcoin by verifying transactions, two things need to happen. First, they need to verify 1 megabyte (MB) of transaction information in the bitcoin blockchain, which can in theory be as small as a transaction, but often that megabyte of information amounts to several thousand. transactions, depending on how much data each transaction stores. This is the easy part.

Second, to add a block of transactions to the blockchain, miners must solve a complex problem in computer mathematics, also known as a “function test.” What the miners are really trying to do is find a 64-digit hexadecimal number, called a sharp, that is less than or equal to the target sharp. Basically, a miner’s computer generates hashes at a rate of megahashs per second (MH / s), gigahashs per second (GH / s), or even terachas per second (TH / s) depending on the unit. , producing all possible 64-digit numbers until it finds a solution. In other words, it’s a gamble.

The most recent block difficulty level at the time of writing is over $ 13 billion. In other words, the probability of a computer producing a hash below the target is 1 in 13 billion. Fortunately, modern computer operating systems are capable of generating a huge amount of hash possibilities per second. However, mining bitcoin requires a large amount of energy and sophisticated computer equipment, but we’ll talk about that later.

The difficulty level is adjusted every 2,016 blocks, or roughly every two weeks, with the goal of maintaining a constant extraction rate. In other words, the more the miners compete for a solution, the more difficult the problem becomes. The reverse is also true. If you remove the computing power from the network, the difficulty is adjusted downward to make mining easier.

How to face competition from millions of other miners?

If the probability of 1 in 13 billion doesn’t seem difficult enough, now let’s explain the other factor that makes mining BTC even more difficult. Not only do bitcoin miners have to find the right crypto hash, but they have to be the first to do it.

Since bitcoin mining is essentially a guessing job, finding the right answer before another miner is about knowing how quickly the miner’s computer can produce hashes. Just ten years ago, bitcoin mining could be done competitively on regular desktops. Over time, however, miners realized that the graphics cards commonly used for video games were more efficient and began to dominate gaming. In 2013, bitcoin miners began using computers specifically designed to mine the most. effectively possible encrypted currencies, called ASICs (Application-Specific Integrated Circuits). These specialized computers for

Today bitcoin mining is so competitive that it can only be done profitably with the most powerful and modern ASICs. When using desktops, GPUs, or older models of ASICs, the cost of power consumption actually exceeds the revenue generated by the cryptocurrencies obtained. Even with the most recent unit available, a computer is seldom enough to compete with what miners call “mining pools”, also known as mining groups.

A mining pool is a group of miners who combine their computing power and distribute the mined bitcoins among the participants. A disproportionate number of bitcoin blockchains are mined by mining groups rather than individual miners. Mining groups and companies have amassed large percentages of BTC computing power.

Is Bitcoin mining sustainable today?

With a probability of 1 in 13 billion possibilities, increasing difficulty levels, and the huge network of users controlling transactions, a block of transactions is checked approximately every 10 minutes. But it’s important to remember that 10 minutes is a goal, not a rule.

The Bitcoin network can process around seven transactions per second, and transactions are logged into the blockchain every ten minutes. By comparison, Visa can process approximately 24,000 transactions per second. However, as the network of bitcoin users continues to grow, the number of transactions completed in 10 minutes will eventually exceed the number of transactions that can be processed in 10 minutes. At that point, the wait times for transactions will begin and continue to lengthen, unless a change is made to the bitcoin protocol.

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 combat scaling, there is less consensus on how to do it. Two solutions have been proposed to solve the problem of scaling. The developers made some suggestions:

  1. Create a secondary “off-chain” layer for the Bitcoin network that would allow faster transactions than the blockchain can verify later.
  2. Increase the number of transactions that each block can store.

With less data to check per block, Solution 1 would make transactions faster and cheaper for miners. Solution 2 would solve the scaling problem by allowing more information to be processed every 10 minutes by increasing the block size.

In July 2017, bitcoin miners and mining companies accounting for around 80-90% of the network’s computing power voted to incorporate a program that reduces the amount of data needed to verify each block. In other words, they went for solution 1.

The program is called SegWit, this term is a fusion of ‘Segregated’, which means to separate, and ‘Witness’, which means witness and refers to the signatures in a bitcoin transaction. Therefore, in this separate witness context, it is a matter of separating the signatures from the transactions of a block and joining them as an extended block. While adding a single program to the bitcoin protocol doesn’t seem like a solution, signature data is estimated to represent up to 65% of the data processed in each transaction block.

Less than a month later, in August 2017, a group of miners and developers embarked on a difficult fork, letting the bitcoin network create a new cryptocurrency using the same base code as bitcoin. While this group agreed on the need for a solution to scaling, they worried that adopting separate cryptocurrency technology would not entirely solve the problem of scaling.

The resulting currency, called “bitcoin cash”, increased the block size to 8MB to speed up the verification process and allow throughput of around 2 million transactions per day. Since that day, there has been a heated debate between supporters of both systems, with each group arguing that their version of Bitcoin is the “real Bitcoin”. On November 14, 2019, Bitcoin Cash was valued at around $ 228.98 while the value of Bitcoin on that day was $ 7,044.
