Instead, they 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 allow a performance of around two million transactions every 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 from the ground. However, bitcoin isnt physical, so why do we call it mining

Because its like gold mining in the bitcoins exist in the protocols design (like the gold exists underground), but they havent been brought out into the mild yet (just as the golden hasnt yet been awakened ). The bitcoin protocol stipulates that 21 million bitcoins will exist at some point.

They get to do this 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 which runs the bitcoin applications and helps to keep bitcoin running by participating in the relay of information. Anyone can run a node, you just download the bitcoin software (free) and also leave a certain port open (the downside is the fact that it consumes energy and storage space the network at time of writing carries up about 145GB).

One node will send information to some 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 fairly fast. .

Some nodes are mining nodes (usually referred to as miners). These set outstanding transactions into blocks and add them into the blockchain. How do they do this By solving a intricate mathematical puzzle that is 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 the data in the block and passed via a hash function, produces a result that's within a certain range.

(For trivia lovers, this number is called a nonce, which is 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 which makes it impossible to forecast 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 must begin with a pre-established number of zeroes.

Whats more, there may 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 acquire a resulting hash within the desirable 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 puzzle number for the next one. As a reward for its own work, the victorious miner has some new bitcoin. .

At the time of writing, the reward is 12.5 bitcoins, which at use this link time of writing is worth nearly \$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 luck and computing power (the more guessing calculations you can execute, the luckier you're ).

Additionally, the costs of being a mining node are considerable, not only due to the powerful hardware needed (if you've got a faster processor than your competitors, you have a better chance of finding the right number before they do), but also because of the large amounts of power that running these processors consumes. .

And, the number of bitcoins awarded as a reward for solving the puzzle will decrease. Its 12.5 now, however, it pits each four decades or so (the next one is anticipated in 2020-21). The her response value of bitcoin relative to price of power and hardware could extend up over the next few decades to partly 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 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 highest number of 21 million click for info has been attained (anticipated some time in 2140).
