4 Simple Techniques For Free Bitcoin Mining Game
Insteadthey went with Solution 2. The resulting currency, known as 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 bitcoin mining, you envisage coins being dug out of the ground. But bitcoin isnt physical, 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 is underground), but they havent been introduced into the mild yet (like the golden hasnt been dug up). The bitcoin protocol stipulates that 21 million bitcoins will exist at some point.
They get to perform this as a reward for creating blocks of validated transactions and including them in the blockchain.
Backtracking a bit, lets talk about nodes. A node is a powerful computer that 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 applications (totally free ) and also leave a certain port open (the drawback is that it consumes energy and storage space the network at time of writing carries up about 145GB).
One node will send information to a few nodes that it knows, who will relay the information to nodes that they know, etc.. That way it ends up getting around the entire network fairly fast. .
Some nodes are mining nodes (usually known as miners). These set outstanding transactions into cubes and add them into the blockchain. How do they do this By solving a complex mathematical puzzle that's a portion of the bitcoin program, and including the answer in the block. The mystery that needs solving is to find a number which, when combined with all the information in the block and passed through a hash function, produces a result that is 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 guess the mystery number and use the hash function to the combination of that guessed number and also the data in the cube. The resulting hash has to begin with a pre-established number of zeroes.
Whats more, there may be several nonces that make the desired result, or there might be none (in the event the miners keep trying, but using a different block configuration). .
The first miner to get a resulting hash within the desirable range announces its victory to the remainder of the network. All the other 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 gets some new bitcoin. .
In the time of writing, the reward is 12.5 bitcoins, which in time of writing will be 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 opponents, you have 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 value of bitcoin relative to cost of electricity and hardware could go up during the next few years to partially compensate this reduction, but its not certain. .
The difficulty of the calculation (the required number of zeroes at the beginning of the hash string) is adjusted 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 to get a continuous and diminishing flow of new coins until the highest number of 21 million has been attained (expected some time in 2140).
