In 2009, it was 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 rate of halving, the total 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's the catch. In order for bitcoin miners to actually earn bitcoin from verifying transactions, two things have to happen. First, they need to confirm 1 megabyte (MB) worth of transactions, which can technically be as small as 1 transaction but are more often several thousand, depending on how much data each transaction stores.

Second, in order to put in a block of transactions to the blockchain, miners should solve a intricate computational math problem, also called a"proof of work" What they're doing is trying to come up with a 64-digit hexadecimal number, known as a"hash," that's less than or equal to the target hash.

In other words, it is a gamble. .

The difficulty level of the most recent block at the time of writing is about 7,184,404,942,701. That is, the chance of a pc producing a hash below the target is just 1 in 7,184,404,942,701 less than 1 in 7 trillion. That level is adjusted every 2016 cubes, or about every two weeks, with the goal of keeping rates of mining constant.

The reverse is also correct. If computational power is taken off of the network, the difficulty adjusts downward to earn mining easier. .

"Say I tell three friends I'm thinking of a number between 1 and 100, and that I write that number on a sheet of paper and seal it in an envelope. My friends don't need to guess the exact number, they simply must be the very first person to guess any number that's less than or equal to this number I am thinking of.

"Let us say I am thinking of the number 19. If Friend A guesses 21, they lose because 21>19. If Friend B supposes 16 and Friend C supposes 12, then they've both technically came at viable answers, because 16<19 and 12<19. There's no'extra credit' for Friend B, even though B's answer was nearer to the goal answer of 19. .

"Now imagine I present the'imagine what number I'm thinking of' question, however I am not asking just three friends, and I am not thinking of a number between 1 and 100. Instead, I am asking millions of would-be miners and I'm thinking about a 64-digit hexadecimal number. Now you see that it's going to be extremely difficult to guess the right answer." .

If 1 in seven trillion doesn't sound difficult enough as is, here is the catch to the catch. Not only do bitcoin miners have to come up with the right hash, but they also have to be the first to perform it.

Because bitcoin mining is essentially guesswork, arriving at the ideal answer before another miner has almost everything to do with how fast your computer can create hashes. Just a decade ago, bitcoin miners can be performed competitively on normal desktops. Over time, however, miners realized that pictures cards visit our website commonly used for video games were more capable of mining than desktops and graphics processing units (GPU) came to dominate the match.

These can run from $500 to the tens of thousands. .

Today, bitcoin mining is so competitive that it can only be done profitably using the latest up-to-date ASICs. When using desktop computers, GPUs, or elderly models of ASICs, the expense of energy consumption actually surpasses the revenue generated. Even with the newest unit available, one pc is rarely enough to compete with what what miners call"mining pools" .

A mining pool is a group of miners that combine their computing power and divide the mined bitcoin between participants. A disproportionately large number of blocks are mined by pools rather than by individual miners. In July 2017, mining pools and companies represented roughly 80% to 90 percent of bitcoin computing power. .

Between 1 in 7 trillion odds, scaling difficulty levels, and the massive network of consumers verifying transactions, one block of transactions is confirmed roughly every 10 minutes. However, its important to keep in mind that 10 minutes is a target, not a guideline.

The bitcoin network can process about seven transactions per second, with transactions being logged in the blockchain each 10 minutes. As the network of bitcoin consumers continues to grow, however, the number of transactions made in 10 minutes will eventually exceed the number of transactions that can be processed in 10 minutes.
