# Things about Free Bitcoin Mining Game

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 permit a performance of around 2 million transactions every 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. But bitcoin isnt bodily, 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 light yet (just as the golden hasnt been awakened ). The bitcoin protocol stipulates that 21 million bitcoins will exist at some point.

They get to perform so as a reward for creating cubes of confirmed transactions and including them in the blockchain.

Backtracking a bit, lets talk about 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 simply download the bitcoin software (totally free ) and also 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 a few nodes which it knows, who will relay the information to nodes that they know, etc.. That way it ends up getting around the entire network fairly quickly. .

Some nodes are mining nodes (usually referred to as miners). These set outstanding transactions into blocks and add them to the blockchain. How do they do so by solving a intricate mathematical mystery that's a portion of this bitcoin app, and including the answer in the block. The puzzle that needs solving is to find a number which, when combined with all the information in the block and passed through a hash function, creates a result that's within a certain range.

(For fiction fans, this number is known as a nonce, which is a concatenation of number used once. In the instance 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 what the outcome will be. So, miners suppose the puzzle number and apply the hash function to the combination of that guessed number and the information in the cube. The resulting hash has to begin with a pre-established number of zeroes.

Whats more, there might be several nonces that make the intended 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 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 figure out the puzzle number for the next one. As a reward for the work, the victorious miner gets some new bitcoin. .

At the time of writing, the payoff is 12.5 bitcoins, which at 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 that benefit, and it's a question of luck and computing power (the further guessing calculations you can perform, the luckier you're ).

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

And, the number of all bitcoins awarded as a reward for solving the mystery will decrease. Its 12.5 now, but it pits each four her comment is here years or so (the next one is anticipated in 2020-21). The value of bitcoin relative to cost of power and hardware could go up during the next few years to partly compensate this reduction, but its not certain. .

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

Why 10 minutes That is the amount of time the bitcoin programmers think is necessary for a continuous and diminishing flow of new coins until the maximum number of 21 million has been attained (anticipated some time in 2140).
