Instead, they went with Solution 2. The resulting currency, called bitcoin money, increased the blocksize to 8 Mb in order to accelerate the verification procedure 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 out of the ground. But bitcoin isnt bodily, so why do we call it mining
Since its similar to gold mining in that the bitcoins exist in the protocols design (just as the gold is underground), but they havent been introduced into the mild yet (like the gold 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 cubes 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 applications 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 the fact that it consumes energy and storage space the network at time of writing takes up about 145GB).
One node will send information to some nodes that 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 group outstanding transactions into blocks and add them to the blockchain. How do they do this By solving a complex mathematical puzzle 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, produces a result that's within a certain range.
How can they find this number By guessing at random. The hash function makes it impossible to forecast what the output will be. So, miners suppose the puzzle number and apply the hash function to the combination of the guessed number and also the data in the block. The resulting hash must begin 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 acquire a resulting hash within the desired range announces its victory to the rest of the network. The rest of the miners immediately cease work on that block and start 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 is worth almost $200,000.
Also, the costs of being a mining node are considerable, not only because of the effective hardware needed (in case you've got a faster processor than your competitors, you have a better chance of finding the correct number before they do), but also due to 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, but it pits each four years or so (the next one is expected in 2020-21). The worth of bitcoin relative to cost of power and hardware could extend up during the next few years to partly compensate this reduction, find this 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 that it takes on average about 10 minutes to process a block.
Why 10 minutes That is the amount of time that the bitcoin programmers think is necessary for a continuous and diminishing flow of new coins until the highest number of 21 million is attained (anticipated some time in 2140).
