The result of “bitcoin mining” is twofold. First, once computers solve these advanced maths issues on the Bitcoin network, they produce new BTC, not unlike when a mining operation extracts gold from the ground.

Chances are you hear the phrase “bitcoin mining” and your mind begins to wander to the Western fantasy of pickaxes, dirt, and hanging it wealthy. As it turns out, that analogy isn’t too far off.

Far less glamourous however equally unsure, bitcoin mining is performed by high-powered computers that thereforelve advanced process maths issues (read: so advanced that they can not be resolved by hand).

The luck and work required by a computer to solve one of these problems is the equivalent of a miner striking gold in the ground — while digging in a sandbox. At the time of writing, the odds of a computer solving one of these problems is 1 in 6 trillion, but more on that later.

The result of “bitcoin mining” is twofold. First, once computers solve these advanced maths issues on the BTC network, they produce new BTC, not unlike when a mining operation extracts gold from the ground. And second, by resolution process maths issues, bitcoin mining make the bitcoin payment network trustworthy and secure, by verifying its transaction information.

There’s a good chance all of that only made so much sense. In order to elucidate however bitcoin mining works in larger detail, let’s begin with a method that’s a bit bit nearer to home: the regulation of written currency.

What is Bitcoin Mining?

Consumers tend to trust written currencies, a minimum of within the u. s.. That’s because the U.S. dollar is backed by a central bank called the Federal Reserve. In addition to a host of other responsibilities, the Federal Reserve regulates the production of new money and prosecutes the use of counterfeit currency.

Even digital payments using the U.S. dollar are backed by a central authority. When you make an online purchase using your debit or credit card, for example, that transaction is processed by a payment processing company such as Mastercard or Visa.

In addition to recording your transaction history, those companies verify that transactions are not fraudulent, which is one reason your debit or credit card may be suspended while traveling.

Bitcoin, on the opposite hand, is not regulated by a central authority. Instead, bitcoin is backed by various computers across the planet referred to as “miners.” This network of computers performs the same function as the Federal Reserve, Visa, and MasterCard, but with a few key differences. Like the Fed, Visa, and MasterCard, bitcoin miners record transactions and check their accuracy.

Unlike those central authorities, however, Bitcoin mining are spread out across the world and record transaction data in a public list that can be accessed by anyone, even you. When someone makes a purchase or sale using bitcoin, we call that a “transaction.

Transactions made in-store and online are documented by banks, point-of-sale systems, and physical receipts. Bitcoin mining win a similar result while not these establishments by clumping transactions along in “blocks” and adding them to a public record referred to as the “blockchain.”

When bitcoin mining add a replacement block of transactions to the blockchain, a part of their job is to form certain that those transactions correct. (More on the magic of however this happens in a very second.) In particular, bitcoin miners make sure that bitcoin are not being duplicated, a unique quirk of digital currencies called “double-spending.

With written currencies, duplicating cash is not a difficulty. Once you spend $20 at the store, that bill is in the clerk’s hands. With digital currency, however, it’s a different story.

Digital info is reproduced comparatively simply, thus with bitcoin mining and different digital currencies, there is a risk that a spender can make a copy of their bitcoin and send it to a different party whereas still holding onto the initial. Let’s return to printed currency for a moment and say someone tried to duplicate their $20 bill in order to spend both the original and the counterfeit at a grocery store.

If a clerk knew that customers were duplicating cash, all they’d need to do is cross-check the bills’ serial numbers. If the numbers were identical, the clerk would know the money had been duplicated. This analogy is comparable to what a bitcoin jack will once they verify new transactions.

With as several as 600,000 purchases and sales occurring in a single day, however, verifying each of those transactions can be a lot of work for miners, which gets at one different key distinction between bitcoin mining and also the Fed, MasterCard or Visa.

As compensation for his or her efforts , miners are awarded bitcoin whenever they add a new block of transactions to the blockchain . The amount of latest bitcoin free with every mined block is named the “block reward.”

The block reward is halved every 210,000 blocks, or roughly every 4 years. In 2009, it was 50. In 2013, it was 25, in 2018 it was 12.5 , and sometime in the middle of 2020 it will halve to 6.25 .

At this rate of halving, the full variety of bitcoin in circulation can approach a limit of twenty one million , creating the currency a lot of scarce and valuable over time however additionally more costly for miners to produce.

How Does Bitcoin Mining Work?

Here’s the catch. In order for bitcoin mining to truly earn bitcoin from validating transactions, two things have to occur. First, they must verify 1 megabyte (MB) worth of transactions, which can theoretically be as small as 1 transaction but are more often several thousand, depending on how much data each transaction stores .

Second, so as to feature a block of transactions to the blockchain, miners should solve a posh machine scientific discipline drawback, conjointly referred to as a “proof of labor”. What they are really doing is trying to come up with a 64-digit hexadecimal number, called a “hash,” that is less than or equal to the target hash.

Basically , a miner’s computer spits out hashes at a rate of megahashes per second (MH/s), gigahashes per second (GH/s) , or even terahashes per second (TH/s) depending on the unit , guessing all possible 64-digit numbers until they arrive at a solution . In other words, it’s a gamble.

How Can You Compete with Millions of Miners?

If 1 in 6 trillion doesn’t sound difficult enough as is, here’s the catch to the catch. Not solely do bitcoin miners need to return up with the correct hash , they even have to be the primary to try to to it .

Because bitcoin mining is actually approximation , incoming at the correct answer before another labourer has nearly everything to try to to with how briskly your laptop will manufacture hashes.

Just a decade agone, bitcoin miners may be performed competitively on traditional desktop computers. Over time, however, miners realised that graphics cards usually used for video games were simpler at mining than desktops and graphics process units (GPU) came to dominate the sport .

In 2013 bitcoin miners began to use computers designed specifically for mining cryptocurrency as with efficiency as doable , known as Application-Specific Integrated Circuits (ASIC) . These can run from $500 to the tens of thousands.

Today, bitcoin mining is therefore competitive that it will solely be done fruitfully with the foremost up-to-date ASICs. When mistreatment desktop computers, GPUs, or older models of ASICs, the cost of energy consumption actually exceeds the revenue generated.

Even with the newest unit at your disposal, one computer is rarely enough to compete with what what miners call “mining pools.”

A mining pool could be a cluster of miners World Health Organization mix their computing power and split the well-mined bitcoin between participants.

A disproportionately sizable amount of blocks area unit well-mined by pools instead of by individual miners. In July 2017, mining pools and corporations diagrammatic roughly eightieth to ninetieth of bitcoin network computing power.

Is Bitcoin Mining Sustainable?

Between 1 in 6 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 mining network will method regarding seven transactions per second, with transactions being logged in the blockchain every 10 minutes .

As the network of bitcoin users continues to grow, however, the amount of transactions created in ten minutes can eventually exceed the amount of transactions which will be processed in 10 minutes.

At that time, waiting times for transactions will begin and continue to get longer , unless a change is made to the bitcoin protocol .

This issue at the guts of the bitcoin protocol is thought as “scaling.”

While bitcoin mining generally agree that something must be done to address scaling, there is less consensus about how do it.

At the time of writing, there are two major solutions to the scaling problem, either (1) to decrease the amount of data needed to verify each block or (2) to increase the amount of transactions that every block will store. With less data to verify per block, the Solution 1 would make transactions faster and cheaper for miners.

Solution a pair of would wear down scaling by allowing a lot of data to be processed each ten minutes.

In July 2017, bitcoin mining companies representing roughly 80% to 90% of the bitcoin network computing power voted to incorporate a program that would decrease the amount of data needed to verify each block.

The program that miners voted to feature to the bitcoin protocol is named a segregated  witness, or SegWit. This term is an amalgamation of Segregated, meaning “to separate,” and Witness, which refers to “signatures on a bitcoin transaction.”

Segregated Witness, then, means to separate transaction signatures from a block — and fix them as associate degree extended block.

While adding one program to the bitcoin network protocol might not seem to be abundant within the method of an answer, signature information has been calculable to account for up to 65% of the data processed in each block of transactions .

Less than a month later in August 2017, a group of miners and developers initiated a hard fork, leaving the bitcoin network to create a new currency using the same codebase as bitcoin .

Although this group agreed with the need for a solution to scaling, they worried that adopting segregated witness technology would not fully address the scaling problem.

Instead, they went with Solution 2. The resulting currency, called “bitcoin cash,” increased the blocksize to 8 Mb in order to accelerate the verification process to allow a performance of around 2 million transactions per day. On February 10, 2019, Bitcoin Cash was valued at $122.45 to Bitcoin’s $3,605.01.
