# Free Satoshi Bitcoin - The Facts

Insteadthey 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 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 brought out into the mild yet (just as the golden hasnt 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 confirmed transactions and including them in the blockchain.

Backtracking a little, lets talk about nodes. A node is a powerful computer that runs the bitcoin software and assists keep bitcoin running by participating in the relay of information. Anyone can run a node, you just 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 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 pretty fast. .

Some nodes are mining nodes (usually known as miners). These group outstanding transactions into cubes and add them into the blockchain. How can they do this By solving a intricate mathematical puzzle that is part of this bitcoin app, and including the answer in the cube. The mystery that needs solving is to find a number which, when combined with the information in the block and passed via a hash function, creates a result that is within a certain range.

(For trivia lovers, this number is known as a nonce, which is a concatenation of number employed 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 makes it impossible to forecast exactly what the outcome will be. So, miners suppose the mystery number and use the hash function to the combination of that guessed number and the data 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 might be none (in which Visit Website case the go to the website miners keep trying, but with a different block configuration). .

The first miner to acquire a resulting hash within the desired range announces its success to the remainder of the network. All the other miners immediately cease have a peek at this site work on that block and begin trying to find out the puzzle number for your next one. As a reward for the own work, the victorious miner gets some new bitcoin. .

At the time of writing, the payoff is 12.5 bitcoins, which in 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 that benefit, and it is a question of fortune and computing power (the more 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 (in case you have a faster processor than your competitors, 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 chips consumes. .

And, the number of all bitcoins given as a reward for solving the mystery will decrease. Its 12.5 now, but it halves every four decades or so (the next one is expected in 2020-21). The worth of bitcoin relative to 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 required number of zeroes at the beginning of the hash string) is adjusted frequently, so that 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 to get a continuous and diminishing flow of new coins until the highest number of 21 million is reached (anticipated some time in 2140).
