# X11 Cryptocurrency for Beginners

Instead, they went with Solution 2. The resulting currency, called bitcoin money, increased the blocksize to 8 Mb in order to accelerate the verification process to allow a performance of around 2 million transactions per 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 similar to gold mining in that the bitcoins exist in the protocols design (just as the gold is underground), but they havent been brought out into the light yet (like the gold hasnt yet been dug up). The bitcoin protocol stipulates that 21 million bitcoins will exist at some point.

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

Backtracking a little, lets discuss nodes. A node is a powerful computer which runs the bitcoin applications and helps keep bitcoin running by participating in the relay of information. Anyone can run a node, you just download the bitcoin software (free) and leave a certain port open (the drawback is 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 that they know, etc.. This way it ends up getting around the entire network fairly quickly. .

Some nodes are mining nodes (usually known as miners). These set outstanding transactions into cubes and add them into the blockchain. How can they do so by solving a complex mathematical puzzle that's 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 all the information in the visit the website cube and passed via a hash function, creates a result that is within a certain range.

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

How can they find this number By guessing at random. The hash function which makes it impossible to forecast what the output will be. So, miners guess the puzzle number and use the hash function to the combination of that guessed number and the information in the block. The resulting hash must begin with a pre-established number of zeroes.

Whats more, there might be several nonces that produce the intended result, or there may be none (in which case the miners keep trying, but with a different block configuration). .

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

At the time of writing, the reward is 12.5 bitcoins, which in time of writing is worth nearly \$200,000.

Although its not nearly as cushy a deal as it sounds. There are a lot of mining nodes competing for this benefit, and it's a question of fortune and computing power (the more guessing calculations you can perform, find this the luckier you are).

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

And, the number of bitcoins given as a reward for solving the puzzle will decrease. Its 12.5 now, however, it halves every four years or so (the next one is expected in 2020-21). The worth of bitcoin relative to cost of electricity and hardware page could go up during the next few decades to partly compensate this reduction, but its not certain. .

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

Why 10 minutes That is the amount of time the bitcoin developers think is necessary for a continuous and diminishing flow of new coins until the highest number of 21 million has been reached (expected some time in 2140).
