Free Satoshi Bitcoin - Truths
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 bitcoin mining, you envisage coins being dug from the ground. However, 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 been awakened ). The bitcoin protocol stipulates that 21 million bitcoins will exist at some point.
They get to do 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 applications 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 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 a few nodes which 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 known as miners). These group outstanding transactions into cubes and add them into the blockchain. How do they do this By solving a intricate mathematical mystery that's a portion of this bitcoin program, and including the answer in the cube. The puzzle that needs solving is to find a number that, when combined with the information in the cube and passed through a hash function, creates a result that is within a certain range.
How do they find this number By guessing at random. The hash function makes it impossible to predict what the output will be. So, miners guess the mystery number and apply the hash function to the combination of that guessed number and also the information in the block. The resulting hash must begin with a pre-established number of zeroes.
Whats more, there might be several nonces that make the intended result, or there may be none (in which case the miners keep trying, but with a different block configuration). .
The first miner to acquire a resulting hash within the desired range announces its success to the rest of the network. The rest of the miners immediately cease work on that block and begin trying to find out the puzzle number for the next one. As a reward for its work, the victorious miner has some new bitcoin. .
In the time of writing, the payoff is 12.5 bitcoins, which at time of writing is worth nearly $200,000.
Also, the costs of being a mining node are considerable, not only due to the effective hardware needed (in case you have a faster processor than your opponents, you have a better chance of finding the right number before they do), but also due to the large amounts of electricity that running these chips consumes. .
And, the number of all bitcoins given as a reward for solving the mystery will decrease. Its 12.5 now, however, it pits each four years or so (the next one is expected in 2020-21). The value of bitcoin relative to price of electricity and hardware could go up during the next few years to partially compensate this reduction, but its not certain. .
The difficulty 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's the amount of time that the bitcoin developers think is necessary to get a steady and diminishing flow of new coins until the highest number of 21 million is attained (expected some time in 2140).
