# Free Bitcoin Mining Game for Dummies

Instead, they went with Solution 2. The resulting currency, known as bitcoin money, increased the blocksize to 8 Mb in order to accelerate the verification process to permit a performance of around 2 million transactions per 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 out of the ground. However, bitcoin isnt physical, so why do we call it mining

Since its like gold mining in that the bitcoins exist in the protocols design (just as the gold is underground), but they havent been brought out into the mild yet (just as the gold 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 blocks of confirmed 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 keep bitcoin running by participating in the relay of information. Anyone can run a node, you just download the bitcoin software (free) and leave a certain port open (the drawback is 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, that will relay the information to nodes they know, etc.. That way it ends up getting around the entire network pretty quickly. .

Some nodes are mining nodes (usually known as miners). These set outstanding transactions into blocks and add them into the blockchain. How can they do this By solving a complex mathematical mystery that's a portion of this bitcoin program, and including the answer in the cube. The puzzle that needs solving is to find a number which, when combined with all the information in the block 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 which makes it impossible to forecast exactly what the outcome 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 block. The resulting hash has to start 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 the event 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 remainder of the network. The rest of the miners immediately cease work on that block and start trying to find out the mystery 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 will be worth nearly \$200,000.

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

Also, the costs of being a mining node are considerable, not only because of the effective hardware needed (in case you've got a faster processor than your opponents, you've got a better chance of finding the correct number before they perform ), but also because of the large amounts of power that running these chips consumes. .

And, the number of all bitcoins given as click here to read a reward for solving the puzzle will decrease. Its 12.5 now, but it halves every four years or so (the next one is anticipated in 2020-21). The worth of bitcoin relative to price of power and hardware could extend 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 it takes on average about 10 minutes to process a block.

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