Everything about Free Bitcoin Mining Game
Instead, they went with Solution 2. The resulting currency, called bitcoin money, increased the blocksize to 8 Mb in order to accelerate the verification process 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 bitcoin mining, you envisage coins being dug out of the ground. But bitcoin isnt physical, 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 brought out into the light yet (just as the golden 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 that runs the bitcoin applications and assists 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 downside 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 pretty quickly. .
Some nodes are mining nodes (usually referred to as miners). These set outstanding transactions into cubes and add them into the blockchain. How do they do so by solving a intricate mathematical mystery that's part of the bitcoin program, and including the answer in the block. The mystery that needs solving is to find a number that, 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 suppose the puzzle number and apply the hash function to the combination of the guessed number and also 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 desired result, or there might 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 success to the remainder of the network. The rest of the miners immediately cease work on that block and start trying to find out the mystery number for the next one. As a reward for the work, the victorious miner has some new bitcoin. .
At the time of writing, the payoff is 12.5 bitcoins, which in time of writing is worth nearly $200,000.
Also, the expenses of being a mining node are considerable, not only due to the effective hardware needed (in case you've got a faster processor than your opponents, you've got 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 bitcoins awarded as a reward for solving the puzzle will decrease. Its 12.5 now, but it halves every four years or so (the next one is expected in 2020-21). The worth of bitcoin relative to price of electricity and hardware could go up during the next few decades to partly compensate this reduction, but its not certain. .
The difficulty of the calculation (the necessary number of zeroes at the beginning of the hash string) is corrected frequently, so that it takes on average approximately 10 minutes to process a block.
Why 10 minutes that's the amount of time that the bitcoin developers think is necessary to get a continuous and diminishing flow of new coins until the maximum number of 21 million has been attained (expected some time in 2140).
