The fortune and work required by a computer to solve one of those 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 solve these complex math issues on the bitcoin networkthey create new bitcoin, not unlike when a mining operation extracts gold from the ground. And second, by solving computational math problems, bitcoin miners create the bitcoin payment network dependable and secure, by verifying its transaction information. .
Theres a good chance all of that only made so much sense. In order to explain how bitcoin mining functions in greater detail, lets begin with a procedure thats just a little bit closer to home: the regulation of printed currency.

Bitcoin miners achieve the exact same effect without these institutions by clumping transactions together in cubes and adding them to a public record called the blockchain. .
When bitcoin miners add a new block of transactions to the blockchain, part of their job is to ensure that these transactions are true. (More on the magic of the way this happens in a second.)

As compensation for their efforts, miners are given bitcoin whenever they include a new block you could check here 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 middle of 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 produce.
Here is the catch. In order for bitcoin miners to actually earn bitcoin from verifying transactions, two why not find out more things must occur. To begin with, they must verify 1 megabyte (MB) value of transactions, which can theoretically be as small as 1 transaction but are far more often several thousand, depending on how much information each transaction shops.
