# 5 Simple Techniques For X11 Cryptocurrency

Insteadthey 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 two million transactions per 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 the bitcoins exist in the protocols design (like the gold is underground), but they havent been brought out into the mild yet (like the gold hasnt yet been awakened ). The bitcoin protocol stipulates that 21 million bitcoins will exist at some point.

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

Backtracking a bit, lets discuss 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 software (free) and leave a certain port open (the downside 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 some nodes which it knows, that will relay the information to nodes they know, etc.. This way it ends up getting around the whole network pretty quickly. .

Some nodes are mining nodes (usually referred to as miners). These set outstanding transactions into cubes and add them to the blockchain. How can they do this By solving a complex mathematical mystery that is a portion of the bitcoin program, and including the answer in the cube. The puzzle that needs solving is to find a number which, when combined with the information in the block and passed through a hash function, produces 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 case 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 predict exactly what the output will be. So, miners suppose the mystery number and apply the hash function to the combination of the guessed number and the information in the cube. The resulting hash has to begin with a pre-established number of zeroes.

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

The first miner to get a resulting hash within the desired range announces its victory to the rest of the network. The rest of the miners immediately cease work on that block and begin trying to figure out the puzzle number for the next one. As a reward for its work, the victorious miner has 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.

Although its not nearly as cushy a bargain as it sounds. There are a whole lot of mining nodes competing for this reward, and it is a question of fortune and computing power (the more guessing calculations you can perform, more the luckier you are).

Additionally, the expenses of being a mining node are considerable, not only because of the powerful hardware needed (if you've got a faster processor than your opponents, you've got a browse around here better chance of finding the right number before they do), but also because of 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, however, it pits each four years or so (the next one is anticipated in 2020-21). The worth of bitcoin relative to cost of power and hardware could go up over the next few years to partially compensate this reduction, but its not certain. .

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

Why 10 minutes that's the amount of time that the bitcoin programmers think is necessary to get a continuous and diminishing flow of new coins until the maximum number of 21 million is attained (anticipated some time in 2140).
