Blockchain (in short) is a distributed database, the data of which is updated through an algorithm for reaching a mathematical consensus.
What does all this mean?
A copy of the database is kept encrypted on many computers around the world at once, so that only the original owners and creators of the data can actually understand the data.
Updating the data and the database works using specific, mathematically guaranteed rules where any new information must be not substantially but mathematically accepted by all parties.
The movement of data in the database is structured into transmissions, which in turn are arranged in time, for example in 10-minute blocks. And the blocks in turn are connected by a mathematical chain. Hence the name blockchain or blockchain.
We use a storybook as a metaphor, where the words on the pages are information transmissions and the pages are blocks. If any “word” is taken from any “page”, this “word” is related to all the words “both on the pages” and the following “words and pages” and gives the whole “book and story” or block chain. The author creates new “words” in the “book”, the reader has access to read them, and the “printing house and the librarian” take care of “creating the pages of the book and sharing the book”. However, “words” can only be understood by the authors of the “words” and, with permission, by readers. However, the methodology of printing a “book”, the logic behind the words “the purpose, nature and nature of a particular” book “are transparent and well known. In other words: the content is hidden from the public, but the form is very well known and can be checked at any time. The “addition of new pages to the book” is subject to the consent of all “librarians and printers”. They can give their consent to the creation of new “words” and to the “printing of pages” by knowing exactly the mathematical rules of form and form, but they do not need to know the direct meaning of “content or words”.
A way to ensure the printing of new “words” that are reliable and logically fit into our “book” as a metaphor.
In order to ensure the suitability and reliability of the whole “book”, the new “words” and the “pages”, “printers and librarians” have to do special work that is not directly related to the distribution, printing or keeping of the book.
Adding each new “page” to the “book” involves an average of 10 minutes of hard work, which is figuratively “digging a hole” of about 1 m3.
While the “page” section is waiting for new “words” in the “print queue”, “all librarians and printers are digging holes with shovels”. The first worker to get a 1m3 hole ready with a micrometer accuracy raises the shovel up and shouts “Done!” After that, the staff of all the “printing houses and libraries” go to the “hole”, quickly measure it and confirm that it is accurate. Along with fixing the precision of the so – called “hole”, it is also ensured that the “words in the print order” are reasonable and now get a new “page” in the book, the number of which is linked to the coordinates of the “hole” just dug. If a villain wants to add “unrelated filth” or other ugliness to a “book,” he must “dig more precise holes at once than all the printers and librarians put together.” As a result, creating a situation where creating logically “words suitable for continuation” is hundreds of times cheaper than trying to “hide any off-topic filth”.
As “printers and librarians” are involved in a large amount of time-consuming undeclared work and bureaucracy, “printers and librarians” also want to be paid well for their work.
But not everyone gets a salary, but only an “employee who dug a hole”.
The salary consists of two parts, first of all “eg 0.01 g of printed black for each new word in the book”. As new “words” come in thousands of times a second, the salary is motivating enough to both “print and share” the book. Printed black can later be exchanged for cash on the public market. An additional motivation for the recognized winner-miner will be the award for “creating the next 5 pages of copyright full words”.
As a remark, it should be added that all the necessary information describing the form and process is immediately available to the public and as transparent as possible.
The block circuit has eliminated one problem that was previously considered unsolvable, which always occurs in distributed systems
This problem is described as follows:
“Byzantine troops surround the city of Rome. Each unit is commanded by its own general, for example a total of 5 units. One of the generals thinks that dawn is a good time to attack. In order to conquer the entire city of Rome, all troops should attack at once. The commanding general is now tasked with sending the messenger information to the other generals that we will all attack together at the next dawn. He immediately has two problems. (a) how he can be sure that the message has reached the generals of the other units. How does he know that a messenger, for example, has not been shot or taken in the meantime? b) How can he be sure that the message he received has not changed in the meantime? The messenger may have been a traitor. Another general may also be a traitor. In other words, how can the reliability of information in a given distributed system be ensured, even if the number of troops and generals decreases or increases? To that end, traitors and external attackers should be completely excluded. ”
The blockchain system, with its consensus-building algorithm, has solved this task well enough. In other words, thanks to the blockchain system, today we can build reliable and corruption-free distributed systems to help any area of life in today’s society.
