In other words, it is a bet. .

The difficulty level of the most recent block at the time of writing is all about 7,184,404,942,701. In other words, the chance of a pc producing a hash beneath the goal is just 1 in 7,184,404,942,701 less than 1 in 7 trillion. That amount is adjusted every 2016 blocks, or about every 2 weeks, with the goal of keeping rates of mining constant.

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

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

"Let us say I am thinking about the number 19. If Friend A guesses 21, they lose because 21>19. If Friend B guesses 16 and Friend C guesses 12, then they have both theoretically arrived 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 target answer of 19. .

"Now imagine that I present the'imagine what number I am thinking of' question, but I'm not asking only three friends, and I am not thinking of a number between 1 and 100. Instead, I'm 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 ideal answer." .

If 1 in 7 trillion doesn't sound hard enough as is, here is the grab to the grab. Not only do bitcoin miners need to come up with the ideal hash, they also have to be the very first to do it.

Since bitcoin mining is essentially guesswork, arriving at the right answer before another miner has everything to do with how fast your computer can create hashes. Only a decade ago, bitcoin miners could be performed competitively on normal desktop computers. As time passes, however, miners recognized that pictures cards commonly used for video games were more effective at mining than desktops and graphics processing units (GPU) came to dominate the match.

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

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

A mining pool is a group of miners who combine their computing ability and divide the mined bitcoin between participants. A disproportionately anchor high number of cubes are mined by pools rather than by individual miners. In July 2017, mining pools and companies represented approximately 80% to 90 percent of bitcoin computing power. .

Between 1 in 7 trillion chances, scaling difficulty levels, and also 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 goal, not a guideline.

The bitcoin network can process about seven transactions per second, with transactions being logged in the blockchain every 10 minutes. Since the network of bitcoin users 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.

This dilemma at the center of the bitcoin protocol is known as scaling. While bitcoin miners generally agree that something must be done in order to deal with scaling, there is less consensus about how can it. At the time of writing, there are two major solutions to this scaling problem, either (1) to decrease the amount of data needed to verify each block or (2) to increase the number of transactions that each block can store.

Solution 2 would cope with scaling by allowing for much more information to be processed each 10 minutes. .

In July 2017, bitcoin miners and mining companies representing approximately 80% to 90 percent of the networks computing power required to incorporate a program that will decrease the amount of data needed to confirm each block. In other words, they went with Solution 1.

The program that miners voted to add to the bitcoin protocol is called a segregated witness, or SegWit. This term is an amalgamation of Segregated, meaning to separate, and Witness, which refers to signatures on a bitcoin transaction. Segregated Witness, then, means to separate transaction signatures out of a block and attach them as an extended block.
