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 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 about bitcoin mining, you envisage coins being dug out of the ground. But bitcoin isnt bodily, 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 (like the golden hasnt been awakened ). 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 discuss nodes. A node is a powerful computer that runs the bitcoin software and assists to keep bitcoin running by participating in the relay of information. Anyone can run a node, you just download the bitcoin applications (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 which it knows, who will relay the information to nodes they know, etc.. That way it ends up getting around the whole network fairly fast. .
Some nodes are mining nodes (usually referred to as miners). These group outstanding transactions into cubes and add them into the blockchain. How do 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 the information in the more tips here cube and passed through a hash function, produces a result that is within a certain range.
(For trivia lovers, 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 which makes it impossible to predict exactly what the outcome will be. So, miners guess the puzzle number and use the hash function to the combination of the guessed number and also the data in the block. The resulting hash must start with a pre-established number of zeroes.
Whats more, there may be several nonces that make the intended result, or there may be none (in the event the miners keep trying, but using a different block configuration). .
The first miner to acquire a resulting hash within the desired range announces its success to the rest of the network. The rest of the miners immediately stop work on that block and begin trying to figure out the puzzle 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 payoff is 12.5 bitcoins, which at time of writing will be worth nearly $200,000.

Although its not nearly as cushy a deal as it sounds. There are a lot of mining nodes competing for that reward, and it is a question of luck 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 powerful hardware needed (if you've got a faster processor than your competitors, you have a better chance of finding the right number before they perform ), but also due to the large amounts of electricity that running these processors consumes. .
And, the number of all bitcoins given as a reward for solving the mystery will decrease. Its 12.5 now, but it halves every four years or so (the next one is anticipated in 2020-21). The worth of bitcoin relative to price of electricity and hardware could extend up over the next few years to partially compensate this reduction, but its not certain. . visit this site
The difficulty of this calculation (the required number of zeroes at the beginning of the hash string) is corrected frequently, so it takes on average approximately 10 minutes to process a block.
Why like it 10 minutes that's the amount of time the bitcoin developers think is necessary for a steady and diminishing flow of new coins until the highest number of 21 million has been attained (anticipated some time in 2140).
