Instead, they went with Solution 2. The resulting currency, called 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 about bitcoin mining, you envisage coins being dug from the ground. But bitcoin isnt physical, so why do we call it mining

Because its like gold mining in that the bitcoins exist in the protocols design (like the gold exists underground), but they havent been introduced into the mild yet (like the gold hasnt yet been awakened ). 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 discuss nodes. A node is a powerful computer that runs the bitcoin applications and assists keep bitcoin running by participating in the relay of information. Anyone can run a node, you simply 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 carries up about 145GB).

One node will send information to some nodes which it knows, who will relay the information to nodes that they know, etc.. This way it ends up getting around the entire network fairly quickly. .

Some nodes are mining nodes (usually referred to as miners). These group outstanding transactions into cubes and add them into the blockchain. How can they do so by solving a intricate mathematical mystery that is part of the bitcoin program, and including the answer in the block. The mystery that needs solving is to find a number which, when combined with the see here data in the cube and passed through 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. The hash function which makes it impossible to predict exactly what the outcome 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 cube. The resulting hash has to start 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 with 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. 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. .

At the time of writing, the payoff is 12.5 bitcoins, which in time of writing will be worth almost \$200,000.

Though its not nearly as cushy a bargain as it sounds. There are a 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 ).

Additionally, 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 competitors, you have a better chance of finding the correct number before they do), but also because of the large amounts of electricity that running these processors consumes. .

And, the number of bitcoins awarded as a reward for solving the mystery will decrease. Its 12.5 now, however, it pits each four decades or so (the next one is expected in 2020-21). The worth of bitcoin relative to price of power and hardware could extend up during the next few years to partly compensate this reduction, but its not certain. .

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

Why 10 minutes that's the amount of time the bitcoin developers 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).
