Insteadthey 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. In 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 out of 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 (just as the gold exists underground), but they havent been brought out into the mild yet (like the gold hasnt yet 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 little, lets talk about nodes. A node is a powerful computer which 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 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 a few nodes that it knows, who will relay the information to nodes that they know, etc.. This way it ends up getting around the entire network pretty fast. .

Some nodes are mining nodes (usually known as miners). These group outstanding transactions into cubes and add them to the blockchain. How can they do so by solving a complex mathematical puzzle that's a portion of the bitcoin app, and including the answer in the cube. The mystery that needs solving is to find a number which, when combined with the data in the cube and passed via a hash function, creates a result that is within a certain range.

(For trivia lovers, this number is known as a nonce, which can be a concatenation of number employed once. In the case of bitcoin, the nonce is an integer between 0 and 4,294,967,296.)

How can they find this number By guessing at random. great site The hash function which makes it impossible to predict exactly what the output will be. So, miners suppose the puzzle number and use the hash function to the combination of that guessed number and the information in the cube. The resulting hash must 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 which case the miners keep trying, but using a different block configuration). .

The first miner to acquire a resulting hash within the desirable range announces its success to the rest of the network. All the other miners immediately stop work on that block and begin trying to figure out the puzzle number for your next one. As a reward for its work, the victorious miner gets some new bitcoin. .

In the time of writing, the reward is 12.5 bitcoins, which in time of writing is 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's a question of fortune and computing power (the more guessing calculations you can perform, the luckier you're ).

Also, the expenses of being a mining node are considerable, not only due to the effective hardware needed (if you have a faster processor than your opponents, you have a better chance of finding the right number before they perform ), but also due to 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 decades to partly compensate this reduction, but its not certain. .

The problem of this calculation (the necessary number of zeroes at the beginning of the hash string) is corrected frequently, so that it requires on average approximately 10 minutes to process a block.

Why 10 minutes That is the amount of time the bitcoin programmers think is necessary to get a steady and diminishing flow of new coins until the highest number of 21 million has been attained (expected some time in 2140).
