# The Single Strategy To Use For X11 Cryptocurrency

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

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

Since its like gold mining in the bitcoins exist in the protocols design (just as the gold exists underground), but they havent been brought out into the light yet (just as the gold hasnt been dug up). The bitcoin protocol stipulates that 21 million bitcoins will exist at some point.

They get to do this as a reward for creating blocks 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 applications and assists to keep bitcoin running by participating in the relay of information. Anyone can run a node, you just download the bitcoin software (totally free ) and also 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 some nodes that it knows, that will relay the information to nodes they know, etc.. This way it ends up getting around the entire network pretty quickly. .

Some nodes are mining nodes (usually known as miners). These set outstanding transactions into blocks and add them into the blockchain. How do they do this By solving a intricate mathematical puzzle that is a portion of the bitcoin program, and including the answer in the cube. The puzzle that needs solving is to find a number which, when combined with all the data in the cube and passed via a hash function, produces a result that's within a certain range.

(For trivia lovers, this number is known as a nonce, which can be a concatenation of number used once. In the case 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 exactly what the outcome will be. So, miners their website suppose the puzzle number and apply the hash function to the combination of that guessed number and also the data in the cube. The resulting hash must begin with a pre-established number of zeroes.

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

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

In the time of writing, the payoff 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 whole lot of mining nodes competing for that benefit, and it's a question of fortune and computing power (the further guessing calculations you can perform, the luckier you are).

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 competitors, 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 bitcoins awarded as a reward for solving the mystery 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 price of power and hardware could go up over the next few decades to partly compensate this reduction, but its not certain. .

The problem of the calculation (the necessary number of zeroes at the beginning of the hash string) is adjusted frequently, so that 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 maximum number of 21 million has been attained (expected some time in 2140).
