Insteadthey went with Solution 2. The resulting currency, called bitcoin money, increased the blocksize to 8 Mb in order to accelerate the verification procedure to allow 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 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 (like the gold is underground), but they havent been brought out into the mild 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 perform so as a reward for creating cubes of validated transactions and including them in the blockchain.
Backtracking a bit, lets discuss 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 just download the bitcoin applications (totally 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 some nodes that it knows, that will relay the information to nodes they know, etc.. This way it ends up getting around the whole network fairly quickly. .
Some nodes are mining nodes (usually referred to as miners). These set outstanding transactions into cubes and add them to the blockchain. How can they do so by solving a intricate mathematical mystery that's part 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 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 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 the information 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 intended result, or there might be none (in the event the miners 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 begin trying to figure out the puzzle number for your next one. As a reward for its own 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 expenses of being a check this mining node are considerable, not only because of the powerful hardware needed (if you have a faster processor than your competitors, you have a better chance of finding the right number before they perform ), but also because of 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, however, it pits each four decades or so (the next one is anticipated in 2020-21). The worth of bitcoin relative to price of power and hardware could extend up during 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 is the amount of time that the bitcoin developers think is necessary for a continuous and diminishing flow of new coins until the maximum number of 21 million has been attained (expected some time in 2140).
