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 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. But 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 introduced into the light yet (just as the golden hasnt been awakened ). The bitcoin protocol stipulates that 21 million bitcoins will exist at some point.
They get to perform this as a reward for creating blocks of confirmed transactions and including them in the blockchain.
Backtracking a little, lets talk about nodes. A node is a powerful computer which runs the bitcoin software 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 drawback is that it consumes energy and storage space the network at time of writing carries up about 145GB).
One node will send information to a few nodes which it knows, that will relay the information to nodes they know, etc.. That way it ends up getting around the whole 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 intricate mathematical puzzle that's part of this bitcoin app, and including the answer in the block. The puzzle that needs solving is to find a number which, when combined with the information in the block and passed via a hash function, produces 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 suppose the mystery number and use the hash function to the combination of the guessed number and 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 make the desired result, or there might be none (in which case the miners pop over here keep trying, but with 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 start trying to find out the mystery number for the next one. As a reward for the work, the victorious miner gets some new bitcoin. .
In the time of writing, the reward 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 due to the effective hardware needed (if you've got a faster processor than your competitors, you have a better chance of finding the right number before they do), but also due to the large amounts of electricity that running these chips consumes. .
And, the number of bitcoins given as a reward for solving the puzzle will decrease. Its 12.5 now, however, it halves every four years get more or so (the next one is anticipated in 2020-21). The worth of bitcoin relative to cost of electricity and hardware could go up over the next few decades to partially 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 about 10 minutes to process a block.
Why 10 minutes that's the amount of time the bitcoin programmers think is necessary for a continuous and diminishing flow of new coins until the maximum number of 21 million has been reached (expected some time in 2140).
