Instead, they went with Solution 2. The resulting currency, called bitcoin cash, increased the blocksize to 8 Mb in order to accelerate the verification procedure 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 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 that 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 yet been awakened ). 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 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 software and assists keep bitcoin running by participating in the relay of information. Anyone can run a node, you just 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 carries up about 145GB).
One node will send information to some nodes that it knows, who will relay the information to nodes they know, etc.. This way it ends up getting around the whole network fairly fast. .
Some nodes are mining nodes (usually known as miners). These set outstanding transactions into cubes and add them to the blockchain. How do they do so by solving a intricate mathematical mystery that is part of this bitcoin program, and including the answer in the cube. The mystery that needs solving is to find a number that, when combined with the data in the block and passed through a hash function, creates a result that is within a certain range.
How do they find this number By guessing at random. The hash function makes it impossible to forecast exactly what the outcome will be. So, miners guess the puzzle number and apply the hash function to the combination of that guessed number and the data in the block. The resulting hash must start with a pre-established number of zeroes.
Whats more, there might be several nonces that produce the desired result, or there may be none (in the event the miners keep trying, but using a different block configuration). .
The first miner to get a resulting hash within the desired range announces its success to the remainder of the network. All the other miners immediately cease work on that block and begin trying to figure out the mystery number for your next one. As a reward for its work, the victorious miner has some new bitcoin. .
At the time of writing, the reward is 12.5 bitcoins, which at time of writing will be worth nearly $200,000.
Also, 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 processors consumes. .
And, the number of bitcoins given as a reward for solving the mystery will decrease. Its 12.5 now, however, it pits each four years or so (the next one is expected in 2020-21). The value of bitcoin relative to cost of electricity and hardware could go up during the next few decades 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 approximately 10 minutes to process a block.
Why 10 minutes that's the amount of time that 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).
