Chances are you hear the term bitcoin mining and your mind begins to wander to the Western fantasy of pickaxes, soil, and striking it rich. As it turns out, that analogy isnt too far off.
Far less glamorous but equally uncertain, bitcoin mining is performed by high-definition computers which solve complex computational science issues (read: so complex they cannot be solved by hand). The fortune and work required 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 result of bitcoin mining is twofold. To begin with, when computers resolve these complex mathematics issues on the bitcoin network, they produce new bitcoin, not unlike when a mining operation extracts gold in the ground. And second, by solving computational mathematics problems, bitcoin miners create the bitcoin payment network dependable and protected, 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 detail, lets begin with a process thats a little bit closer to home: the regulation of printed currency.

Consumers tend to anticipate printed currencies, at least in the United States. Thats because the U.S. dollar is backed with a central bank known as the Federal Reserve. In addition to a host of other responsibilities, the Federal Reserve modulates the production of new money and prosecutes the usage of counterfeit currency. .
Even electronic payments using the U.S. dollar are backed by a central authority. When you make an online order using your debit or credit card, by way of example, that transaction is processed by a payment processing company like Mastercard or Visa. In addition to recording your transaction history, those companies affirm that transactions are not fraudulent, which is one reason that your credit or debit card could be suspended while traveling. .
Bitcoin, on the other hand, is not controlled by a central authority. Instead, bitcoin is endorsed by millions of computers across the world called miners. This network of computers performs the same function as the Federal Reserve, Visa, and Mastercard, but using 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 purchase using bitcoin, we predict that a transaction. Transactions generated in-store and online are documented by banks, point-of-sale methods, and bodily receipts. Bitcoin miners achieve the exact same effect without these institutions by clumping transactions together in blocks and adding them to a public document known as the blockchain. .
When bitcoin miners put in a new block of transactions to the blockchain, a part of their job is to ensure that those transactions are true. (More on the wonder of how this happens click now in a second) In particular, bitcoin miners make sure that bitcoin are not being duplicated, a unique quirk of digital currencies called double-spending.

If the numbers were identical, the clerk would know the money had been replicated. This analogy is similar to what a bitcoin miner does when they confirm new transactions. .
With as many as 600,000 purchases and sales occurring in a single day, however, verifying each of these transactions can be a lot of work for miners, which gets at one other crucial look at this website 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.
In 2009, it had been 50. In 2013, it had been 25, in 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 valuable over time but also more expensive for miners to make.
Here's 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 theoretically be as small as 1 transaction but are far more often a few thousand, depending on how much data each transaction shops.
