Everything about X11 Cryptocurrency
Instead, they went with Solution 2. The resulting currency, called bitcoin cash, increased the blocksize to 8 Mb in order to accelerate the verification process to permit a performance of around 2 million transactions per 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 from the ground. However, bitcoin isnt bodily, so why do we call it mining
Because 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 mild yet (just as the gold hasnt 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 talk about 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 just download the bitcoin applications (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 takes up about 145GB).
One node will send information to some nodes that it knows, who will relay the information to nodes that they know, etc.. That 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 blocks and add them into the blockchain. How can they do this By solving a complex mathematical mystery that is a portion 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 the data in the cube and passed via 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 predict exactly what the output will be. So, miners suppose the puzzle number and use the hash function to the combination get more of the guessed number and the data in the block. The resulting hash has to start 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 the event the miners keep trying, but with a different block configuration). .
The you can try this out first miner to get a resulting hash within the desired range announces its success to the remainder of the network. All the other miners immediately cease work on that block and begin trying to find out the puzzle number for the next one. As a reward for the work, the victorious miner has some new bitcoin. .
At 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 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 perform ), but also because of the large amounts of power that running these processors consumes. .
And, the number of bitcoins given as a reward for solving the puzzle will decrease. Its 12.5 now, but it halves every four decades or so (the next one is expected in 2020-21). The worth of bitcoin relative to price of power and hardware could extend up over the next few years to partly 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 about 10 minutes to process a block.
Why 10 minutes That is the amount of time the bitcoin developers think is necessary to get a steady and diminishing flow of new coins until the maximum number of 21 million has been attained (expected some time in 2140).
