Free Satoshi Bitcoin - An Overview
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 from the ground. However, bitcoin isnt physical, so why do we call it mining
Since its like gold mining in that the bitcoins exist in the protocols design (like the gold exists underground), but they havent been introduced into the mild yet (like the golden 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 blocks of confirmed 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 to keep bitcoin running by participating in the relay of information. Anyone can run a node, you simply download the bitcoin software (free) and leave a certain port open (the downside is the fact that it consumes energy and storage space the network at time of writing carries up about 145GB).
One node will send information to some nodes that it knows, who will relay the information to nodes that they know, etc.. That way it ends up getting around the whole network pretty 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 intricate mathematical puzzle that is part of the bitcoin program, and including the answer in the block. The mystery that needs solving is to find a number which, when combined with all the information in the cube and passed through a hash function, creates a result that's within a certain range.

How do they find this number By guessing at random. The hash function which makes it impossible to predict what the outcome will be. So, miners suppose the puzzle number and apply the hash function to the combination of the guessed my sources number and also the data in the cube. The resulting hash must start with a pre-established number of zeroes.
Whats more, there might be several nonces that make the desired result, or there may 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 desirable range announces its victory to the remainder of the network. The rest of the miners immediately stop work on that block and start trying to figure check that out the puzzle number for the next one. As a reward for the work, the victorious miner has some new bitcoin. .
At the time of writing, the payoff is 12.5 bitcoins, which at time of writing will be worth almost $200,000.

Additionally, the costs of being a mining node are considerable, not only because of the effective hardware needed (in case you have a faster processor than your competitors, you have 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 all bitcoins given as a reward for solving the mystery will decrease. Its 12.5 now, however, it pits each four decades or so (the next one is expected in 2020-21). The value of bitcoin relative to cost of power and hardware could extend up during the next few decades to partially compensate this reduction, but its not certain. .
The difficulty of this calculation (the required number of zeroes at the beginning of the hash string) is adjusted frequently, so that it takes on average about 10 minutes to process a block.
Why 10 minutes that's the amount of time that the bitcoin programmers think is necessary to get a continuous and diminishing flow of new coins until the maximum number of 21 million is attained (expected some time in 2140).
