# X11 Cryptocurrency Fundamentals Explained

Insteadthey went with Solution 2. The resulting currency, known as bitcoin cash, increased the blocksize to 8 Mb in order to accelerate the verification procedure to permit a performance of around two million transactions every day. At the time of writing, Bitcoin Cash is valued at \$545.00 to Bitcoins \$6,328.11.

When you hear bitcoin mining, you envisage coins being dug out of the ground. But bitcoin isnt physical, so why do we call it mining

Because its like gold mining in that the bitcoins exist in the protocols design (like the gold is underground), but they havent been introduced into the mild yet (just as the golden hasnt yet been awakened ). The bitcoin protocol stipulates that 21 million bitcoins will exist at some point.

They get to do so as a reward for creating cubes of validated transactions and including them in the blockchain.

Backtracking a little, lets talk about nodes. A node is a powerful computer that runs the bitcoin software and helps to keep bitcoin running by participating in the relay of information. Anyone can run a node, you simply download the bitcoin applications (free) and leave a certain port open (the drawback is the fact that it consumes energy and storage space the network at time of writing takes up about 145GB).

One node will send information to a few nodes that it knows, who will relay the information to nodes they know, etc.. That way it ends up getting around the entire network pretty fast. .

Some nodes are mining nodes (usually referred to as miners). These set outstanding transactions into cubes and add them into the blockchain. How can they do so by solving a intricate mathematical mystery that is a portion of the bitcoin program, and including the answer in the block. The puzzle that needs solving is to find a number that, when combined with the information in the block and passed through a hash function, creates a result that's within a certain range.

(For fiction fans, this number is called a nonce, which is a concatenation of number employed once. In the instance of bitcoin, the nonce is an integer between 0 and 4,294,967,296.)

How do they find this number By guessing at random. The hash function makes it impossible to predict exactly what the output will be. So, miners suppose the puzzle number and use the hash function to the combination of that guessed number and the data in the cube. The resulting hash has to begin with a pre-established number of zeroes.

Whats more, there may be several nonces that make the desired result, or there might be none (in the event the miners keep trying, but with a different block configuration). .

The first miner to get a resulting look what i found hash within the desirable range announces its success to the remainder of the network. All the other miners immediately cease work on that block and start trying to find out the mystery number for your next one. As a reward for its own work, the victorious miner gets some new bitcoin. .

In the time of writing, the reward is 12.5 bitcoins, which at time of writing is worth almost \$200,000.

Though its not nearly as cushy a bargain as it sounds. There are a whole lot of look at here mining nodes competing for this benefit, and it's a question of fortune and computing power (the further guessing calculations you can execute, the luckier you're ).

Additionally, the expenses of being a mining node are considerable, not only due to the effective hardware needed (if you have a faster processor than your opponents, you've got a better chance of finding the right number before they perform ), but also because of the large amounts of power that running these chips consumes. .

And, the number of all bitcoins given as a reward for solving the puzzle will decrease. Its 12.5 now, but it pits each four decades or so (the next one is anticipated in 2020-21). The value of bitcoin relative to cost of power and hardware could go up during the next few decades to partially compensate this reduction, but its not certain. .

The problem of this calculation (the required number of zeroes at the beginning of the hash string) is adjusted frequently, so it takes on average approximately 10 minutes to process a block.

Why 10 minutes that's the amount of time the bitcoin developers think is necessary to get a continuous and diminishing flow of new coins until the maximum number of 21 million has been reached (anticipated some time in 2140).
