# 6 Simple Techniques For X11 Cryptocurrency

Insteadthey went with Solution 2. The resulting currency, known as bitcoin money, increased the blocksize to 8 Mb in order to accelerate the verification process to permit a performance of around 2 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 from the ground. However, 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 introduced into the mild yet (like the gold 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 blocks of validated transactions and including them in the blockchain.

Backtracking a bit, lets talk about nodes. A node is a powerful computer that runs the bitcoin applications and assists 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 downside 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 which it knows, that will relay the information to nodes that they know, etc.. This way it ends up getting around the entire network pretty quickly. .

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 complex mathematical puzzle 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 all the information in the block and passed through a hash function, creates a result that is within a certain range.

(For trivia lovers, 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 do they find this number By guessing at random. The hash function makes it impossible to predict exactly what the outcome will be. So, miners suppose the mystery number and apply the hash function to the combination of the guessed number and also the information in the block. The resulting hash must begin with a pre-established number of zeroes.

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

The first miner to get a resulting hash within the desired range announces its victory to the rest 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 the work, the victorious miner gets some new bitcoin. .

In the time of writing, the payoff is 12.5 bitcoins, which in time of writing will be worth nearly \$200,000.

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

Additionally, the costs of being a mining node are considerable, not only due to the effective hardware needed (in case you've got a faster processor than your opponents, you have a better chance of finding the correct number before they perform ), but also due to the large amounts of electricity 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 halves every four years or so (the next one is anticipated in 2020-21). The value of bitcoin relative to cost of Look At This power and hardware could go up during the next few years to partly compensate this reduction, but its not certain. .

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

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