# X11 Cryptocurrency Fundamentals Explained

Insteadthey 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 allow 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 bitcoin mining, you envisage coins being dug out of the ground. But bitcoin isnt bodily, so why do we call it mining

Because its similar to gold mining in the bitcoins exist in the protocols design (like the gold is underground), but they havent been introduced into the light yet (just as the gold hasnt yet been dug up). The bitcoin protocol stipulates that 21 million bitcoins will exist at some point.

They get to do this 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 that runs the bitcoin applications and helps keep bitcoin running by participating in the relay of information. Anyone can run a node, you simply download the bitcoin software (totally free ) and leave a certain port open (the downside is 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 that it knows, who will relay the information to nodes they know, etc.. This way it ends up getting around the entire network pretty fast. .

Some nodes are mining nodes (usually referred to as miners). These group outstanding transactions into cubes and add them into the blockchain. How do they do so by solving a complex mathematical mystery that's part of the bitcoin app, and including the answer in the cube. The puzzle that needs solving is to find a number that, when combined with all the information in the block and passed through a hash function, creates a result that is 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 do they find this number By guessing at random. The hash function makes it impossible to forecast what the output will be. So, miners guess the mystery number and use the hash function to the combination of that guessed number and also the information in the cube. The resulting hash must start 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 the event the miners keep trying, but with a different block configuration). .

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

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

Though 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 further guessing calculations you can execute, the luckier you are).

Also, the expenses of being a mining node are considerable, not only because of the effective hardware needed (if you have a faster processor than your opponents, you have a better chance of finding the right number before they do), but also due to the large amounts of electricity that running these chips consumes. .

And, the number of bitcoins given as a reward for solving the mystery will decrease. Its 12.5 now, however, it pits each four years or so (the next one is anticipated in 2020-21). The value of bitcoin relative to price of electricity and hardware could go up over the next few decades to partially why not try this out compensate this more info here reduction, but its not certain. .

The problem of the calculation (the necessary number of zeroes at the beginning of the hash string) is corrected 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 to get a steady and diminishing flow of new coins until the highest number of 21 million has been reached (anticipated some time in 2140).
