But first: A quick backstory
Mining
Introduction
Mining is the process of adding transaction records to Bitcoin's public ledger of past transactions (and a "mining rig" is a colloquial metaphor for a single computer system that performs the necessary computations for "mining". This ledger of past transactions is called the What is bitcoin mining modules definition chain as it is a chain of blocks. The blockchain serves to confirm transactions to bittcoin rest wjat the biycoin as having taken place. Bitcoin nodes use the blockchain to distinguish legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere.
Mining is intentionally designed to be resource-intensive and detinition so that the number of blocks found each day by miners remains steady. Individual blocks must contain a proof of work to be considered valid. This proof of work is verified by other Bitcoin nodes each time they receive a block. Bitcoin uses the hashcash proof-of-work function.
The What is bitcoin mining modules definition purpose of mining is to set the history of transactions in a way that is computationally impractical to modify by any one entity. By downloading and verifying the blockchain, bitcoin nodes are able to reach consensus about the ordering of events in bitcoin.
Mining is also the mechanism used to introduce Bitcoins into the system: Miners are paid any transaction fees as well as a "subsidy" of newly created coins. This both serves the purpose of disseminating new coins in a decentralized manner as well as motivating people to provide security for the system.
Bitcoin mining is so called because it resembles the mining of other commodities: it requires exertion and it slowly makes new units available to anybody who wishes to take part. An important difference is that the supply does not depend on the amount of mining. In general changing total miner hashpower does not change how many bitcoins are created over the long term.
Difficulty
The Computationally-Difficult Problem
Mining a block is difficult because the SHA-256 hash of a block's header minign be lower than or equal to What is bitcoin mining modules definition target in order for the block to be What is bitcoin mining modules definition by the network. This problem can be simplified for explanation mibing The hash of a block must start with a certain number of zeros. The probability of calculating a hash that starts with many zeros is very low, therefore many attempts must be made. In order to generate a new hash each round, a nonce is incremented. See Proof of work for more information.
The Difficulty Metric
The What is bitcoin mining modules definition is the measure of how difficult it is to find a new block compared to the easiest it can ever be. The rate is recalculated every 2,016 blocks to a value such that the previous bitccoin blocks would have been generated in exactly one fortnight (two weeks) had everyone been mining at this difficulty. This is expected yield, on average, one block every ten mihing.
As more wnat join, the rate of block creation increases. As the rate of block generation increases, the difficulty rises to compensate, which has a balancing of effect due to reducing the rate of block-creation. Any blocks released by malicious miners that do not meet the required difficulty target will simply be rejected by the other participants in the network.
Reward
When a block is discovered, the discoverer may award themselves a certain number of bitcoins, which is agreed-upon by everyone in the network. Currently this bounty is 12.5 bitcoins; this value will halve every 210,000 blocks. See Controlled Currency Supply.
Additionally, the miner is awarded the fees paid by users sending transactions. The fee is an incentive for the miner to include the transaction in their block. In the minijg, as the number of new bitcoins miners are allowed to create in each block dwindles, the fees will make up a much more important whzt of mining income.
The mining ecosystem
Hardware
Users have used various types of hardware over time to mine blocks. Hardware specifications and performance statistics are defijition on the Mining Modiles Comparison page.
CPU Minin Bitcoin client versions allowed users to use their CPUs to mine. The advent of GPU mining made CPU mining financially unwise as the hashrate of the network grew to such a degree that the amount of bitcoins produced by CPU mining became lower than What is bitcoin mining modules definition cost of power to operate a CPU. The option was therefore removed from the core Bitcoin client's user interface.
GPU Mining
GPU Mining is drastically faster and more efficient than CPU mining. See the whxt article: Why a GPU mines faster wnat a CPU. A variety of modulse mining rigs have been documented.
FPGA Mining
FPGA mining is a very efficient and fast way to mine, mkdules to GPU mining and drastically outperforming CPU mining. FPGAs typically consume very small amounts of power with relatively high hash ratings, making them more viable and efficient than GPU mining. See Mining Hardware Comparison for FPGA hardware specifications and statistics.
ASIC Mining
An application-specific integrated circuit, or ASIC, is a microchip designed and manufactured for a very specific purpose. ASICs designed for Bitcoin mining were first released in 2013. For the amount of power they consume, they are vastly faster than all previous technologies and already have made GPU mining financially.
Mining services (Cloud mining)
Mining contractors provide mining services with performance specified by contract, often shat to as a "Mining Contract." They may, for example, rent out a specific level of mining capacity for a set price at a specific duration.
Pools
As more and more miners competed for the limited supply of blocks, individuals found that they were working for months without finding a block and receiving any reward for their mining efforts. This made mining something of a gamble. To address the variance in their income miners started organizing themselves into pools so What is bitcoin mining modules definition they could share rewards more evenly. See Pooled mining and Comparison of mining pools. bitcpin public ledger (the "block moeules was started on January 3rd, 2009 at 18:15 UTC presumably by Satoshi Nakamoto. The first block is known as the genesis block. The first transaction recorded in the first block was a single transaction What is bitcoin mining modules definition the reward of 50 new bitcoins to its creator.
Staking
Staking is a concept whah the Delegated proof of stake coins, closely resembling pooled mining of proof of work coins. According to the proof of share principle, instead of computing powers, the partaking users are pooling their Stakes, certain amounts of money, blocked on their wallets and delegated to the pool’s staking balance.
The network periodically selects a pre-defined number of top staking pools (usually between 20 and 100), based on their staking balances, and allows them to validate transactions in order to get a reward. The rewards are then shared with the delegators, according to their stakes with the pool.
Although staking doesn’t require lots of computing power as mining, it still needs very stable and fast Internet connection in order to collect, verify mofules sign all transactions in the queue within a small timespan, which can be as short as one second. If a pool fails to do so, it doesn’t get the reward, and it may be shared What is bitcoin mining modules definition definitoin next pool in order.

Bitcoin Mining, Explained
Chances are you hear the phrase “bitcoin mining” and your mind begins to wander to the Western fantasy of pickaxes, dirt and striking it rich. As it turns out, What is bitcoin mining modules definition analogy isn’t too far off.
Far less glamorous but equally uncertain, bitcoin mining is performed by high-powered computers that solve complex computational math problems (that is, so complex that they cannot be solved by hand, and indeed complicated enough to tax even incredibly powerful computers). 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 chance of a computer solving one of these problems is about 1 in 13 trillion, but more on that later.
The result of “bitcoin mining” is twofold. First, when computers What is bitcoin mining modules definition these complex math problems on the Bitcoin network, they produce new bitcoin (when referring to the individual coins themselves, "bitcoin" typically appears without capitalization), not unlike when a mining operation extracts gold from the ground. And second, by solving computational math problems, bitcoin miners 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 explain how bitcoin mining works in greater detail, let’s begin with a process that’s a little bit closer to home: the regulation of printed currency.
Bitcoin Basics: How Bitcoin Differs From Traditional Currencies
Consumers tend to trust printed currencies, at least in the United States. 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 the federal government 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 other hand, is not regulated by a central What is bitcoin mining modules definition. Instead, Bitcoin is backed by millions What is bitcoin mining modules definition computers across the world called “nodes.” This network of computers performs the same function as the Federal Reserve, Visa and Mastercard, but with a few key differences. Nodes store information about prior transactions and help to verify their authenticity. Unlike those central authorities, however, Bitcoin nodes are spread out across the world and record transaction data in a public list that can be accessed by anyone, even you.
Bitcoin Basics: What Is Cryptocurrency Mining?
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 miners achieve the same effect without these institutions by clumping transactions together in “blocks” and adding them to a public record called the “blockchain.” Nodes then maintain records of those blocks so that they can be verified into the future.
When bitcoin miners add a new block of transactions to the blockchain, part of their job is to make sure that those transactions are accurate. (More on the magic of how this happens in a second.) In particular, bitcoin miners make sure that bitcoin is not being duplicated, a unique quirk of digital currencies called “double-spending.” With printed currencies, duplicating money isn't an issue. 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 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. Let's return to printed currency for a moment and say someone tried to duplicate their $20 bill in What is bitcoin mining modules definition to spend both the original and the counterfeit at What is bitcoin mining modules definition grocery store. If a clerk knew that customers were duplicating money, all they would have to do is look at the bills’ serial numbers. If the numbers were identical, the clerk would know the money had been duplicated. This analogy is similar to what a bitcoin miner does What is bitcoin mining modules definition they verify new transactions.
Rewarding Miners
With as many as 500,000 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 other key difference between bitcoin miners and the Federal Reserve, Mastercard or Visa. As compensation for their efforts, miners are awarded bitcoin whenever they add a new block of transactions to the blockchain. The amount of new bitcoin released with each mined block is called 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 total number of bitcoin in circulation will approach a limit of 21 million, making the currency more scarce and valuable over time but also more costly for miners to produce.
How Does Bitcoin Mining Work?
Here's the catch. In order for bitcoin miners to actually earn bitcoin from verifying 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 What is bitcoin mining modules definition several thousand, depending on how much data each transaction stores. This is the easy part.
Second, in order to add a block of transactions to the blockchain, miners must solve a complex computational math problem, also called a "proof of work." What they're actually 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 What is bitcoin mining modules definition 64-digit numbers until they arrive at a solution. In other words, it's a gamble.
The difficulty level of the most recent block at the time of writing is more than 13 trillion. That is, the chance of a computer producing a hash below the target is 1 in 13 trillion. To put that in perspective, you are about 44,500 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. Fortunately, mining computer systems spit out many, many more hash possibilities than that. Nonetheless, mining for bitcoin requires massive amounts of energy and sophisticated computing rigs, but more about that later as well.
The difficulty level is adjusted every 2016 blocks, or roughly every 2 weeks, with the goal of keeping rates of mining constant. That is, the more miners there are competing for a solution, the more difficult the problem will become. The opposite is also true. If computational power is taken off of the network, the difficulty adjusts downward to make mining easier.
Explain it Like I'm Five What is bitcoin mining modules definition
Here's a helpful analogy to consider:
"Say I tell three friends that I'm thinking of a number between 1 and 100, and I write that number on a piece of paper and seal it in an envelope. My friends don't have to guess the exact number, they just have to be the first person to guess any number that is less than or equal to the number I am thinking of. And there is no limit to how many guesses they get.
"Let's say I'm thinking of the number 19. If Friend A guesses 21, they lose because 21>19. If What is bitcoin mining modules definition B guesses 16 and Friend C guesses 12, then they've both theoretically arrived at viable answers, because 16<19 and 12<19. There is no 'extra credit' for Friend B, even though B's answer was closer to the target answer of 19.
"Now imagine that I pose the 'guess what number I'm thinking of' question, but I'm not asking just three friends, and I'm not thinking of a number between 1 and 100. Rather, I'm asking millions of would-be miners and I'm thinking of a 64-digit hexadecimal number. Now you see that it's going to be extremely hard to guess the right What is bitcoin mining modules definition How Can You Compete with Millions of Miners?
If 1 in 13 trillion doesn't sound difficult enough as is, here's the catch to the catch. Not only do bitcoin miners have to come up with the right hash, but they also have to be the first to do it.
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. Just a decade ago, bitcoin mining could be performed competitively on normal desktop computers. Over time, however, miners realized that graphics cards commonly used for video games were more effective and they began to dominate the game. In 2013, bitcoin miners started to use computers designed specifically for mining cryptocurrency as efficiently as possible, called Application-Specific Integrated Circuits (ASIC). These can run from several hundred dollars to tens of thousands but their efficiency in mining Bitcoin is superior.
Today, bitcoin mining is so competitive that it can only be done profitably with the most up-to-date ASICs. When using desktop computers, GPUs, or older models What is bitcoin mining modules definition ASICs, the cost of energy consumption actually exceeds the revenue generated. Even with the newest unit What is bitcoin mining modules definition your disposal, one computer is rarely enough to compete with what miners call "mining pools."
A mining pool is a group of miners who combine their computing power and split the mined bitcoin between participants. A disproportionately large number of blocks are mined by pools rather than by individual miners. Mining pools and companies have represented large percentages of bitcoin's computing power.
Is Bitcoin Mining Sustainable?
Between 1 in 13 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 process about seven transactions per second, with transactions being logged in the blockchain every 10 minutes. For comparison, Visa can process somewhere around 24,000 transactions per second. As the network of bitcoin users continues to grow, however, the number of transactions made in 10 minutes will eventually exceed the number of transactions that can be processed in 10 minutes. At that point, waiting times for transactions will begin and continue to get longer, unless a change is made to the bitcoin protocol.
This issue at the heart of the bitcoin protocol is known as “scaling.” While bitcoin miners generally agree that something must be done to address scaling, there is less consensus about how to do it. There have been two major solutions proposed to address the scaling problem. Developers have suggested either (1) creating a secondary "off-chain" layer to Bitcoin that would allow for faster transactions that can be verified by the blockchain later, or (2) increasing the number of transactions that each block can store. With less data to verify What is bitcoin mining modules definition block, the Solution 1 would make transactions faster and cheaper for miners. Solution 2 would deal with scaling by allowing for more information to be processed every 10 minutes by increasing block size.
In July 2017, bitcoin miners and mining companies representing roughly 80% to 90% of the network’s computing power voted to incorporate a program that would decrease the amount of data needed to verify each block. That is, they went with Solution 1.
The program that miners voted to add to the bitcoin protocol is called a segregated witness, or SegWit. This term is an amalgamation What is bitcoin mining modules definition 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 attach them as an extended block. While adding a single program to the bitcoin protocol may not seem like much in the way of a solution, signature data has been estimated 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 What is bitcoin mining modules definition of around 2 million transactions per day. On November 6, 2019, Bitcoin Cash was valued at about $302 to Bitcoin’s roughly $9,330.
