Chances are you listen to 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 away.
Far less glamorous but equally uncertain, bitcoin mining is performed by high-powered computers that solve complex computational math problems (read: so complicated they cannot be solved 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.
The result of bitcoin mining is twofold. To begin with, when computers resolve these complex math issues on the bitcoin network, they create new bitcoin, not unlike when a mining operation extracts gold in 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 detail, lets begin with a procedure thats just a tiny bit closer to home: the regulation of printed currency.

Consumers tend to anticipate printed currencies, at least in the United States. Feeling because the U.S. dollar is backed with a central bank known as the Federal Reserve. In addition to a bunch 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. buck are backed by a central authority. When you make an online order using your debit card or charge card, for example, that transaction is processed by means of a payment processing company such as Mastercard or Visa. In addition to recording your transaction history, these companies affirm that transactions are not fraudulent, and that's one reason that your debit or credit card may be suspended while traveling. .
Bitcoin, on the other hand, is not controlled by a central authority. Instead, bitcoin is endorsed by millions of servers across the world known 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 Federal Reserve, Visa, and Mastercard, bitcoin miners record transactions and check their accuracy.

When someone makes a purchase or purchase using bitcoin, we call that a transaction. Transactions generated in-store and online are documented by banks, point-of-sale systems, and bodily receipts. Bitcoin miners achieve the exact same effect without these institutions by clumping transactions together in cubes and adding them into a public document known as the blockchain. .
When bitcoin miners put in 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 bitcoin are not being duplicated, a unique quirk of digital currencies called double-spending.

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

When the numbers were identical, then the clerk could know the money had been duplicated. 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 each of these transactions can be a great deal of work for miners, which gets at one other crucial 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 was 50. In 2013, it was 25, in the time of writing it's 12.5, and sometime in the middle of click here for more 2020 it will halve to 6.25. .
At this speed of halving, the entire number of bitcoin in circulation will approach a limit of 21 million, making the currency more scarce and precious over time but also more expensive for miners to make.
Here is the catch. In order for bitcoin miners to really earn bitcoin from verifying transactions, two things have to happen. To begin with, they need to confirm 1 megabyte (MB) worth of transactions, which can technically be as little as 1 transaction but are more often a few thousand, depending on how much data each transaction shops.
