# 8 Easy Facts About Free Bitcoin Mining Game Shown

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

Since its like gold mining in that the bitcoins exist in the protocols design (like the gold is underground), but they havent been introduced into the mild yet (like the golden 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 cubes of confirmed 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 just download the bitcoin applications (totally 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 some 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 into the blockchain. How can they do this By solving a complex mathematical puzzle that is part of this bitcoin program, and including the answer in the cube. The mystery that needs solving is to find a number that, when combined with the data in the cube and passed via a hash function, produces a result that is within a certain range.

(For trivia lovers, this number is called a nonce, which can be a concatenation of number employed once. In the instance 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 makes it impossible to predict exactly what the outcome will be. So, miners suppose the puzzle number and apply the hash function to the combination of that guessed number and also the information in the block. The resulting hash has to start with a pre-established number of zeroes.

Whats more, there may be several nonces that make the intended result, or there might be none (in the event the miners keep trying, but with a different block configuration). .

The first miner to get a resulting hash within the desirable range announces its success to the remainder of the network. The rest of the miners immediately stop work on that block and start trying to figure out the mystery number for your next one. As a reward for the own work, the victorious miner has some new bitcoin. .

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

Although its not nearly as cushy a bargain as it sounds. There are a lot of mining nodes competing for this benefit, and it's a question of fortune and computing power (the further guessing calculations you can execute, the luckier you're ).

Also, the expenses of being a mining node are considerable, not only because of the powerful hardware needed (in case you've got a faster processor than your opponents, you've got 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 all bitcoins given 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 value of bitcoin relative to review cost of electricity and hardware could extend up during the next few years to partially compensate this reduction, but its not certain. .

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

Why 10 minutes that's the amount of time the bitcoin developers think is necessary for a steady and diminishing flow of new coins until the maximum number of 21 million is reached (anticipated some time in 2140).
