The luck 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 end result of bitcoin mining is twofold. To begin with, when computers resolve these intricate math issues on the bitcoin network, they produce 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 that only made so much sense. In order to explain how bitcoin mining works in detail, lets begin with a procedure thats a tiny bit closer to home: the regulation of printed currency.

With as many as 600,000 purchases and sales occurring in a single day, nevertheless, verifying every one of these transactions can be a lot 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 awarded bitcoin whenever they add a new block of transactions to the blockchain.
In 2009, it had been 50. In 2013, it was 25, in the time of writing it is 12.5, and sometime in the center of 2020 it will Extra resources halve to 6.25. .
At this rate of halving, the entire number of bitcoin in circulation will approach a limit of 21 million, making the currency more scarce and valuable over time but also more costly for miners to produce.
Here is the catch. In order to get bitcoin miners to actually earn bitcoin from verifying transactions, two things must occur. To begin with, they need to confirm 1 megabyte (MB) value of transactions, which can technically be as little as 1 transaction but are more often several thousand, depending on how much information each transaction stores.
