Excitement About Free Bitcoin Mining Game
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 procedure to allow 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 bitcoin mining, you envisage coins being dug from the ground. But bitcoin isnt physical, so why do we call it mining
Since its similar to 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 golden 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 blocks of confirmed transactions and including them in the blockchain.
Backtracking a bit, lets talk about nodes. A node is a powerful computer that runs the bitcoin software and helps keep bitcoin running by participating in the relay of information. Anyone can run a node, you simply download the bitcoin applications (free) and also 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 a few 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 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 puzzle that's part of this bitcoin app, and including the answer in the block. The mystery that needs solving is to find a number that, when combined with all the data in the cube and passed through a hash function, creates a result that's within a certain range.
(For trivia lovers, this number is called 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 what the output will be. So, miners guess the mystery number and use the hash function to the combination of that guessed number and the data in the cube. The resulting hash must start 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 with a different block configuration). .
The first miner to get a resulting hash within the desired range announces its victory to the remainder of the network. All the other miners immediately stop 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 reward is 12.5 bitcoins, which in time of writing will be worth nearly $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 luck and computing power (the more guessing calculations you can perform, the luckier you're ).
Additionally, the expenses of being a mining node are considerable, not only because of the effective hardware needed (in case you've got a faster their website processor than your competitors, 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 all bitcoins given as a reward for solving the mystery 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 years 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 adjusted 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 maximum number of 21 million is reached (expected some time in 2140).
