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, that analogy isnt too far away.
Far less glamorous but equally uncertain, bitcoin mining is performed by high-powered computers that solve complex computational math problems (read: so complex they cannot be solved by hand). The luck and work demanded by a computer to solve one of those problems is that the equivalent of a miner striking gold in the ground while digging in a sandbox.
The end result of bitcoin mining is twofold. First, when computers solve these complex math issues on the bitcoin networkthey produce new bitcoin, not unlike when a mining operation extracts gold from the ground. And second, by solving computational mathematics issues, bitcoin miners make the bitcoin payment network dependable and secure, by verifying its transaction information. .
Theres a fantastic chance all that only made so much sense. In order to explain how bitcoin mining works in greater detail, lets begin with a procedure thats a tiny bit closer to home: the regulation of printed currency.
What Does Bitcoin Trading Company Mean?
Consumers tend to anticipate printed currencies, at least in the United States. Thats because the U.S. dollar is backed by a central bank called the Federal Reserve. In addition to a bunch of other responsibilities, the Federal Reserve regulates the production of new money and prosecutes the usage of counterfeit currency. .
Even digital payments using the U.S. dollar are backed with a central authority. When you make an online purchase using your debit or charge card, by way of instance, that transaction is processed by means of a payment processing company like Mastercard or Visa. In addition to recording your transaction history, these companies verify that transactions are not fraudulent, and that's one reason that your debit or credit card could be suspended while traveling. .
Bitcoin, on the This Site other hand, is not controlled by a central authority. Instead, bitcoin is backed by millions of servers throughout the world known as miners. This network of computers performs the same function as the Federal Reserve, Visa, and Mastercard, but with a couple of important differences. Like the Federal Reserve, Visa, and Mastercard, bitcoin miners record transactions and assess their accuracy.

When someone makes a purchase or sale using bitcoin, we predict a transaction. Transactions generated in-store and online are documented by banks, point-of-sale systems, and physical receipts. Bitcoin miners achieve the exact same effect without these institutions by clumping transactions together in blocks and adding them into a public document called the blockchain. .
When bitcoin miners add a new block of transactions to the blockchain, a part of the job is to ensure that those transactions are true. (More on basics the wonder of the way this happens in a second) In specific, bitcoin miners be certain bitcoin are not being reproduced, a unique quirk of electronic currencies called double-spending.

Once you spend $20 at the shop, that invoice is in the clerks hands. With digital currency, nevertheless, it's a different story. .

If the numbers were identical, the clerk could know the money had been replicated. This analogy is very similar to what a bitcoin miner does when they verify new transactions. .
With as many as 600,000 purchases and sales occurring in a single day, however, verifying every one of these transactions can be a great deal 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 given bitcoin whenever they add a new block of transactions to the blockchain.
In 2009, it had been 50. In 2013, it was 25, at the time of writing it's 12.5, and sometime in the center of 2020 it will halve to 6.25. .
At this speed of halving, the total number of bitcoin in circulation will approach a limit of 21 million, making the currency more scarce and precious find over time but also more expensive for miners to make.
Here is the catch. In order for bitcoin miners to actually earn bitcoin from verifying transactions, two things must happen. To begin with, they need to confirm 1 megabyte (MB) value of transactions, which can technically be as small as 1 transaction but are far more often a few thousand, depending on how much information each transaction stores.
