Insteadthey went with Solution 2. The resulting currency, known as bitcoin money, increased the blocksize to 8 Mb in order to accelerate the verification procedure to permit a performance of around two million transactions per day. In 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. But bitcoin isnt physical, so why do we call it mining
Since its similar to gold mining in the bitcoins exist in the protocols design (just as the gold is underground), but they havent been introduced into the light yet (just as the gold hasnt yet been dug up). The bitcoin protocol stipulates that 21 million bitcoins will exist at some point.
They get to do so as a reward for creating blocks of confirmed transactions and including them in the blockchain.
Backtracking a bit, lets discuss nodes. A node is a powerful computer that runs the bitcoin applications and helps keep bitcoin running by participating in the relay of information. Anyone can run a node, you simply download the bitcoin software (totally 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 which it knows, who will relay the information to nodes that they know, etc.. This way it ends up getting around the whole network pretty quickly. .
Some nodes are mining nodes (usually referred to as miners). These group outstanding transactions into cubes and add them to the blockchain. How do they do so by solving a complex mathematical mystery that is part of the bitcoin program, and including the answer in the block. The puzzle that needs solving is to find a number which, when combined with all the data in the block and passed via a hash function, produces 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 forecast what the output will be. So, miners suppose the mystery number and use the hash function to the combination of that guessed number and also the data in the cube. The resulting hash has to 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 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 rest of the network. All the other 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 work, the victorious miner gets some new bitcoin. .
In the time of writing, the payoff is 12.5 bitcoins, which at time of writing will be worth almost $200,000.
Also, the costs of being a mining node are considerable, not only because of the powerful hardware needed (in case you've got a faster processor than your opponents, you've got a better chance of finding the right number before they do), but also due to the large amounts of power that running these processors consumes. .
And, the number of all bitcoins awarded as a reward for solving the mystery will decrease. Its 12.5 now, however, it halves every four decades or so (the next one is expected in 2020-21). The value of bitcoin relative to price of power and hardware could go you could try here up over the next few decades to partly compensate this reduction, but its not certain. .
The problem of this calculation (the necessary number of zeroes at the beginning of the hash string) is corrected frequently, so it takes on average about 10 minutes to process a block.
Why 10 minutes that's the amount of time the bitcoin programmers think is necessary to get a continuous and diminishing flow of new coins until the highest number of 21 million has been attained (anticipated some time in 2140).
