the Bitcoin network in their blocks. Whatever the accuracy of Motherboards math, theres no disputing the fact that Bitcoin uses a great deal of energy. At this rate 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 costly for miners to produce. Considering the combined electric costs for these operations (covering lighting, air-conditioning, data-centers, website hosting, office equipment and more) the total probably approaches or even exceeds Denmarks current power usage.
Miners achieve this by solving a computational problem which allows them to chain together blocks of transactions (hence Bitcoins famous blockchain). There is no 'extra credit' for Friend B, even though B's answer was closer to the target answer.

Org, that's who you're up against!
Thats why mining pools came into existence. Traditional currencies-like the dollar or euro-are issued by central banks. So how do transactions get confirmed?
