Types of mining bitcoins

Nonetheless, mining has a magnetic appeal for many investors interested in cryptocurrency because of the fact that miners are rewarded for their work with crypto tokens. And if you are technologically inclined, why not do it? However, before you invest the time and equipment, read this explainer to see whether mining is really for you.

We will focus primarily on Bitcoin throughout, we'll use "Bitcoin" when referring to the network or the cryptocurrency as a concept, and "bitcoin" when we're referring to a quantity of individual tokens. The primary draw for many mining is the prospect of being rewarded with Bitcoin.

That said, you certainly don't have to be a miner to own cryptocurrency tokens. An example of a crypto blog platform is Steemit , which is kind of like Medium except that users can reward bloggers by paying them in a proprietary cryptocurrency called STEEM. The Bitcoin reward that miners receive is an incentive that motivates people to assist in the primary purpose of mining: to legitimize and monitor Bitcoin transactions, ensuring their validity.

Because these responsibilities are spread among many users all over the world, Bitcoin is a "decentralized" cryptocurrency, or one that does not rely on any central authority like a central bank or government to oversee its regulation. Miners are getting paid for their work as auditors. They are doing the work of verifying the legitimacy of Bitcoin transactions. By verifying transactions, miners are helping to prevent the " double-spending problem. Double spending is a scenario in which a bitcoin owner illicitly spends the same bitcoin twice.

While there is the possibility of counterfeit cash being made, it is not exactly the same as literally spending the same dollar twice. If you were to try to spend both the real bill and the fake one, someone that took the trouble of looking at both of the bills' serial numbers would see that they were the same number, and thus one of them had to be false. What a Bitcoin miner does is analogous to that—they check transactions to make sure that users have not illegitimately tried to spend the same bitcoin twice.

This isn't a perfect analogy—we'll explain in more detail below. Once miners have verified 1 MB megabyte worth of bitcoin transactions , known as a "block," those miners are eligible to be rewarded with a quantity of bitcoin more about the bitcoin reward below as well. The 1 MB limit was set by Satoshi Nakamoto, and is a matter of controversy, as some miners believe the block size should be increased to accommodate more data, which would effectively mean that the bitcoin network could process and verify transactions more quickly.

It depends on how much data the transactions take up. That is correct. To earn bitcoins, you need to meet two conditions. One is a matter of effort; one is a matter of luck. This is the easy part. This process is also known as proof of work.

The good news: No advanced math or computation is involved. You may have heard that miners are solving difficult mathematical problems—that's not exactly true. It's basically guesswork. The bad news: It's guesswork, but with the total number of possible guesses for each of these problems being on the order of trillions, it's incredibly arduous work.

In order to solve a problem first, miners need a lot of computing power. That is a great many hashes. If you want to estimate how much bitcoin you could mine with your mining rig's hash rate, the site Cryptocompare offers a helpful calculator. In addition to lining the pockets of miners and supporting the bitcoin ecosystem, mining serves another vital purpose: It is the only way to release new cryptocurrency into circulation.

In other words, miners are basically "minting" currency. For example, as of Nov. In the absence of miners, Bitcoin as a network would still exist and be usable, but there would never be any additional bitcoin. There will eventually come a time when Bitcoin mining ends; per the Bitcoin Protocol, the total number of bitcoins will be capped at 21 million. This does not mean that transactions will cease to be verified. Miners will continue to verify transactions and will be paid in fees for doing so in order to keep the integrity of Bitcoin's network.

Aside from the short-term Bitcoin payoff, being a coin miner can give you "voting" power when changes are proposed in the Bitcoin network protocol. The rewards for bitcoin mining are reduced by half every four years. When bitcoin was first mined in , mining one block would earn you 50 BTC. In , this was halved to 25 BTC. By , this was halved again to If you want to keep track of precisely when these halvings will occur, you can consult the Bitcoin Clock , which updates this information in real-time.

Interestingly, the market price of bitcoin has, throughout its history, tended to correspond closely to the reduction of new coins entered into circulation. This lowering inflation rate increased scarcity and historically the price has risen with it. Although early on in Bitcoin's history individuals may have been able to compete for blocks with a regular at-home computer, this is no longer the case.

The reason for this is that the difficulty of mining Bitcoin changes over time. In order to ensure the smooth functioning of the blockchain and its ability to process and verify transactions, the Bitcoin network aims to have one block produced every 10 minutes or so. However, if there are one million mining rigs competing to solve the hash problem, they'll likely reach a solution faster than a scenario in which 10 mining rigs are working on the same problem.

For that reason, Bitcoin is designed to evaluate and adjust the difficulty of mining every 2, blocks, or roughly every two weeks. When there is more computing power collectively working to mine for Bitcoin, the difficulty level of mining increases in order to keep block production at a stable rate. Less computing power means the difficulty level decreases. To get a sense of just how much computing power is involved, when Bitcoin launched in the initial difficulty level was one.

As of Nov. All of this is to say that, in order to mine competitively, miners must now invest in powerful computer equipment like a GPU graphics processing unit or, more realistically, an application-specific integrated circuit ASIC. The photo below is a makeshift, home-made mining machine. The graphics cards are those rectangular blocks with whirring fans.

Note the sandwich twist-ties holding the graphics cards to the metal pole. This is probably not the most efficient way to mine, and as you can guess, many miners are in it as much for the fun and challenge as for the money. The ins and outs of bitcoin mining can be difficult to understand as is.

And there is no limit to how many guesses they get. Let's say I'm thinking of the number There is no "extra credit" for Friend B, even though B's answer was closer to the target answer of 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 Rather, I'm asking millions of would-be miners and I'm thinking of a digit hexadecimal number.

Now you see that it's going to be extremely hard to guess the right answer. In Bitcoin terms, simultaneous answers occur frequently, but at the end of the day, there can only be one winning answer. Typically, it is the miner who has done the most work or, in other words, the one that verifies the most transactions.

The losing block then becomes an " orphan block. Miners who successfully solve the hash problem but who haven't verified the most transactions are not rewarded with bitcoin. Well, here is an example of such a number:.

The number above has 64 digits. Easy enough to understand so far. As you probably noticed, that number consists not just of numbers, but also letters of the alphabet. Why is that? To understand what these letters are doing in the middle of numbers, let's unpack the word "hexadecimal. As you know, we use the "decimal" system, which means it is base This, in turn, means that every digit of a multi-digit number has 10 possibilities, zero through nine.

In a hexadecimal system, each digit has 16 possibilities. But our numeric system only offers 10 ways of representing numbers zero through nine. That's why you have to stick letters in, specifically letters a, b, c, d, e, and f. If you are mining bitcoin, you do not need to calculate the total value of that digit number the hash. I repeat: You do not need to calculate the total value of a hash.

Remember that ELI5 analogy, where I wrote the number 19 on a piece of paper and put it in a sealed envelope? In bitcoin mining terms, that metaphorical undisclosed number in the envelope is called the target hash. What miners are doing with those huge computers and dozens of cooling fans is guessing at the target hash. A nonce is short for "number only used once," and the nonce is the key to generating these bit hexadecimal numbers I keep talking about.

In a memory pool, unconfirmed transactions wait until they are verified and included in a new block. Bitcoin miners compete to validate the transaction using proof of work. The miner who solves the puzzle first shares the result across the other nodes. Once the block has been verified, the nonce has been generated, then the nodes will start granting their approval.

If maximum nodes grant their approval, the block becomes valid and is added to the blockchain. The miner who has solved the puzzle will also receive a reward of The 10 bitcoins for which the transaction was initiated now will be transferred from Beyonce to Jennifer.

In proof of work, a predefined condition the target is adjusted for every 2, blocks, which is approximately every 14 days. The average time to mine a block is 10 minutes, and to keep the time frame for block generation within 10 minutes, the target keeps adjusting itself.

The difficulty of the puzzle changes depending on the time it takes to mine a block. This is how the difficulty of a block is generated: It is the hash target of the first block divided by the hash target of the current block. This is the difficulty being changed after every 2, blocks, so basically it is very hard to generate the proof of work—but it is very easy for the miners to verify once someone have solved the puzzle.

And once the majority of the miners reach a consensus, the block gets validated and added to the blockchain. What if someone tries to hack the data? Each block has solved a puzzle and generated a hash value of its own, which is its identifier. Now suppose a person tries to tamper with block B and change the data. The data is aggregated in the block, so if the data of the block changes, then the hash value that is the digital signature of the block will also change.

It will therefore corrupt the chain after it—the blocks ahead of block B will all get delinked, because the previous hash value of block C will not remain valid. For a hacker to make the entire blockchain valid for the block B that has been changed, he or she would have to change the hash value of all the blocks ahead of block B.

This would require a huge amount of computing power and is next to impossible. In the early days of bitcoin, miners used to solve the mathematical puzzles using regular processors—controlling processor units CPUs. It used to take a lot of time for mining Bitcoins and other cryptocurrencies, even though the difficulty levels were easier than today. As mentioned above, the difficulty level keeps changing and growing, so the miners also had to increase their processing power. They discovered that graphical processing units GPUs proved to be more efficient than regular CPUs, but this also had the drawback of consuming more electricity.

A miner has to calculate the return on investment based on the hardware and the cost of electricity and other resources needed to do the mining. Today miners use hardware called ASIC application-specific integrated circuit , which was specifically introduced for mining Bitcoin and other cryptocurrencies. It consumes less power and has a higher computing power.

Miners are profitable when their cost of resources to mine one block is less than the price of the reward. So, Bitcoin miners use their resources hardware and electricity to verify a transaction, and each time a block is mined, new bitcoins are created in the network. The total supply is limited to 21 million bitcoins; 17 to 18 million bitcoins have already been mined, so only 3 to 4 million are left. As of today, a reward of If individuals buy multiple lottery tickets and pool their tickets together, then this will increase their chances of winning.

If someone wins the lottery, then based on the contribution, the reward is distributed among all the participants. The bitcoin mining pool is similar: Multiple nodes share their resources to mine a block. When a block is solved, the miners split the reward based on the amount of processing power they have invested. The pool members generate a final hash value, then the bitcoin reward gets distributed proportionally among the participants based on the resources they contributed.

You can also see an example of a mining pool, in which the participants are sharing their mining resources, and you can see both the unconfirmed reward for which they are mining and what they have earned so far. New to bitcoin and blockchain and want to learn more?

A block has four fields, or primary attributes: Previous hash: This attribute stores the value of the hash of the previous block, and that's how the blocks are linked to one another. Data: This is the aggregated set of transactions included in this block—the set of transactions that were mined and validated and included in the block. Every block is supposed to generate a hash value, and the nonce is the parameter that is used to generate that hash value. The proof of work is the process of transaction verification done in blockchain.

Hash: This is the value obtained by passing the previous hash value, the data and the nonce through the SHA algorithm; it is the digital signature of the block. What Is Bitcoin Mining? Public distributed ledger: A distributed ledger is a record of all transactions maintained in the blockchain network across the globe.
