The Only Guide to Free Satoshi Bitcoin
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. At 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 from the ground. However, bitcoin isnt physical, so why do we call it mining
Because its like gold mining in that the bitcoins exist in the protocols design (just as the gold exists underground), but they havent been introduced into the mild yet (just as the gold hasnt been dug up). The bitcoin protocol stipulates that 21 million bitcoins will exist at some point.
They get to do so as a reward for creating cubes of validated transactions and including them in the blockchain.
Backtracking a little, lets talk about nodes. A node is a powerful computer which runs the bitcoin applications and assists 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 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 a few nodes which it knows, who 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 referred to as miners). These group outstanding transactions into blocks and add them to the blockchain. How do they do so by solving a complex mathematical puzzle that's part of the bitcoin app, and including the answer in the cube. The puzzle that needs solving is to find a number which, his explanation when combined with all the data in the block and passed via 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 which makes it impossible to predict what the outcome will be. So, miners suppose the puzzle number and use the hash function to the combination of that guessed number and also the data 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 which case the miners keep trying, but using a different block configuration). .
The first miner to get a resulting hash within the desired range announces its victory to the remainder of the network. All the other miners immediately cease work on that block and start trying to figure out the mystery number for the next one. As a reward for its work, the victorious miner has some new bitcoin. .
At the time of writing, the reward is 12.5 bitcoins, which at time of writing is worth almost $200,000.
Additionally, the costs of being a mining node are considerable, not only due to the powerful hardware needed (if you have a faster processor than your competitors, you've got a better chance of finding the right number before they do), but also due to the large amounts of power that running these chips consumes. .
And, the number of bitcoins given as a reward for solving here are the findings the puzzle will decrease. Its 12.5 now, but it pits each four decades or so (the next one is expected in 2020-21). The value of bitcoin relative to price of electricity and hardware could go up over the next few decades 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 corrected frequently, so that it takes 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 for a steady and diminishing flow of new coins until the maximum number of 21 million is attained (anticipated some time in 2140).
