The Basic Principles Of Free Bitcoin Mining Game
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 allow a performance of around 2 million transactions every day. In 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 from 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 exists underground), but they havent been introduced into the light yet (just as the gold 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 blocks of validated transactions and including them in the blockchain.
Backtracking a little, lets discuss nodes. A node is a powerful computer that 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 (free) and leave a certain port open (the downside 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 that it knows, that will relay the information to nodes that they know, etc.. This way it ends up getting around the whole network fairly fast. .
Some nodes are mining nodes (usually known as miners). These group outstanding transactions into blocks and add them into the blockchain. How can they do this By solving a intricate mathematical puzzle that's part of this bitcoin app, and including the answer in the block. The mystery that needs solving is to find a number that, when combined with all the data in the cube and passed through a hash function, produces a result that's within a certain range.
(For trivia lovers, this number is known as a nonce, which can be a concatenation of number used once. In the case of bitcoin, the nonce is an integer between 0 and 4,294,967,296.)
How do 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 mystery number and use the hash function to the combination of that guessed number and the information in the block. The resulting hash has to start with a pre-established number of zeroes.
Whats more, there may be several nonces that produce the intended result, or there may be none (in the event the miners keep trying, but using a different block configuration). .
The first miner to acquire a resulting hash within the desired range announces its victory to the rest of the network. All the other miners immediately stop work on that block and start trying to find out the mystery number for the next one. As a reward for the own 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.
Although its not nearly as cushy a bargain as it sounds. There are a whole lot of mining nodes competing for this reward, and it is a question of fortune and computing power (the more guessing calculations you can execute, the luckier you're ).
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 competitors, you've got a better chance of finding the right number before they perform ), but also because of the large amounts of power Continued that running these chips consumes. .
And, the number of bitcoins awarded as a reward for solving the mystery 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 electricity and hardware could extend up over the next few years 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 adjusted 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 programmers think is necessary for a continuous and diminishing flow of new coins until the highest number of 21 million is reached (anticipated some time in 2140).
