There are three basic types to acquire Bitcoins:
Buy on an exchange, accept them as a means of payment for goods and services, or mine new bitcoins. Mine is a process in which transaction records are added to Bitcoins public account, called a blockchain. It is designed in such a way that every transaction can be confirmed and that each user of the network can access this account. In addition, it can distinguish between legitimate Bitcoin transactions and the attempts to use money already spent.
A process of register management enables computing power through the use of the computer.
A publicly distributed account on which the data records of every Bitcoin transaction are stored.
The blockchain is called this because it consists of several blocks that represent a list of transactions within a certain period. When a block of transactions has been generated, the miners undergo the blocking process. You apply a complex mathematical formula to the information in the block, then form the information into a much short, apparently random sequence of letters and numbers called “Hash”.
A one-time, random sequence with a fixed length can be generated from a data record of each size.
A hash not only consists of information from the block of the transaction but also includes other information. The most important thing is that the hash of the previous block of the blockchain is included.
While it is relatively simple to create a hash from a collection of data, such as a block of transactions, it is almost impossible to find out which data was used by looking at the hash sequence. More importantly, every single hash is unique. If you only change a position of the Bitcoin block, you change the complete hash sequence.
As you can see in the example above, it doesn’t matter how much information is fed in, the hash always stays the same length.
Due to these properties, the hash works like a digital wax seal. If someone manipulates even a block of transactions, the hash will change immediately, and thus also the following hash sequences on the blockchain. Therefore, every attempt to cheat within the Bitcoin network is easily visible to every user.
The miner Bitcoin fundamentally helps you confirm and make sure that each of them is legitimate. They compete with each other and use software written for mines. Every time a new block is ‘closed’, it means that a miner has successfully created a hash sequence, and he or she gets a fee.
At the stand of October 2017, the premium is 12.5 bitcoins per block. This value is halved every time after 210,000 blocks. The entire number of bitcoins is limited. This means that the more coins are mined, the greater the value of each individual. Although the number of bitcoins per block inevitably reduces, the value of the miners’ fee will most likely remain the same or even rise.
Usually, it is extremely easy to derive a hash from a collection of information, computers are pretty good at it. To prevent users from carrying out thousands of transaction blocks per second and mining all bitcoins within minutes, the Bitcoin network has made this process difficult.
This is done by a required ‘Proof of Work’ (statement of execution). It is a system that requires further work for the applicant, mostly connected to the processing time of a computer. Creating a proof of work is a random process with little probability. This means that there are usually many failed attempts before a correct proof of Work is generated. When it comes to bitcoins, the hash is the Proof of Work.
Proof of Work
An economic measure to ensure that fraudulent behavior is contained by asking for further work by the applicant, mostly connected to the computer.
To complicate the mines, even more, some name Bitcoin Difficulty (Bitcoin difficulty) was implemented. It is a benchmark to find a new block compared to the simplest block that can ever exist.
A yardstick is as difficult to generate a correct hash. The value is newly calculated every time in 2016. It was designed so that the mines last about 10 minutes per block. The more miners are added, the higher the rate at which blocks are generated.
