Free Bitcoin Mining Game for Dummies
Insteadthey went with Solution 2. The resulting currency, known as bitcoin cash, 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 about bitcoin mining, you envisage coins being dug out of the ground. However, bitcoin isnt physical, so why do we call it mining
Because its like gold mining in the bitcoins exist in the protocols design (just as the gold is underground), but they havent been brought out into the light yet (just as the golden hasnt yet been awakened ). The bitcoin protocol stipulates that 21 million bitcoins will exist at some point.
They get to do this 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 which runs the bitcoin software and helps to keep bitcoin running by participating in the relay of information. Anyone can run a node, you simply download the bitcoin software (free) and leave a certain port open (the drawback is 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 which it knows, who will relay the information to nodes that they know, etc.. This way it ends up getting around the entire network pretty fast. .
Some nodes are mining nodes (usually known as miners). These set outstanding transactions into cubes and add them into the blockchain. How can they do so by solving a complex mathematical mystery that's a portion of the bitcoin app, and including the answer in the block. The puzzle that needs solving is to find a number which, when combined with the information 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 exactly what the output will be. So, miners suppose the puzzle number and use the hash function to the combination of that guessed number and the information in the cube. The resulting hash must begin with a pre-established number of zeroes.
Whats more, there might be several nonces that produce the desired 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 success to the remainder of the network. All the other miners immediately stop work on that block and start trying to figure out the mystery number for your next one. As a reward for the own work, the victorious miner has some new bitcoin. .
In the time of writing, the reward is 12.5 bitcoins, which in 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 (if you've got a faster processor than your competitors, you've got a better chance of finding the correct number before they perform ), but also due to the large amounts of electricity that running these chips consumes. .
And, the number of all bitcoins awarded as a reward for solving the puzzle will decrease. Its 12.5 now, however, it halves every four years or so (the next one is expected in 2020-21). The worth of bitcoin relative to cost of electricity and hardware could go up during the next few decades to partially compensate this reduction, but its not certain. .
The problem of the calculation (the necessary number of zeroes at look at more info the beginning of the hash string) is adjusted frequently, so that it requires on average approximately 10 minutes to process a block.
Why 10 minutes That is the amount of time that the bitcoin developers think is necessary for a steady and diminishing flow of new coins until the maximum number of 21 million is attained (anticipated some time in 2140).
