All about X11 Cryptocurrency
Insteadthey went with Solution 2. The resulting currency, called bitcoin cash, increased the blocksize to 8 Mb in order to accelerate the verification procedure to permit a performance of around 2 million transactions per day. In 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 from 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 (like the gold exists underground), but they havent been introduced into the light yet (like the golden hasnt yet been dug up). The bitcoin protocol stipulates that 21 million bitcoins will exist at some point.
They get to do this as a reward for creating cubes of validated transactions and including them in the blockchain.
Backtracking a little, lets discuss nodes. A node is a powerful computer which runs the bitcoin software 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 also leave a certain port open (the drawback is the fact 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 set outstanding transactions into blocks and add them to the blockchain. How can they do so by solving a intricate mathematical puzzle that is part of the bitcoin app, and including the answer in the cube. The puzzle that needs solving is to find a number which, when combined with all the information 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 predict what the outcome will be. So, miners guess the puzzle number and use the hash function to the combination of that guessed number and the data in the cube. The resulting hash has to start with a pre-established number of zeroes.
Whats more, there might be several nonces that produce the useful link intended result, or there may 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 desirable range announces its victory to the remainder of the network. All the other miners immediately stop work on that block and start trying to find out the puzzle number for your next one. As a reward for its work, the victorious miner has some new bitcoin. .
In the time of writing, the payoff is 12.5 bitcoins, which straight from the source 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 powerful hardware needed (in case you have a faster processor than your opponents, you've got a better chance of finding the right number before they do), but also because of 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, but it pits each four years or so (the next one is anticipated in 2020-21). The value of bitcoin relative to cost of electricity and hardware could go up over the next few years to partially compensate this reduction, but its not certain. .
The problem of this calculation (the required number of zeroes at the beginning of the hash string) is corrected frequently, so that it requires on average approximately 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 reached (anticipated some time in 2140).
