Finding each subsequent simple solution is a more complex task than for the previous value. In other words, the algorithm for calculating cryptocurrency values is constantly becoming more complex. Moreover, it is becoming more complex exponentially;
all solutions differ from each other (after all, these are mathematical values). This ensures the uniqueness of each virtual coin. However, not only in this way. (More on that later). You can learn more about cryptocurrencies in this article .
The uniqueness of virtual money based
On single mathematical solutions is good. But imagine a situation in which two strangers in different parts of the world suddenly paid with the same cryptocoin (i.e. the same mathematical value). After all, these solutions are simply an electronic record. And if the algorithm for calculating the values of the same Bitcoin is known.
Then what prevents anyone from getting all these solutions for virtual coins.
Regardless of the system) and starting to pay with them? Ideally, every user can start doing this.
That is, it is not enough for cryptocoins to differ from each other simply by their content (the numerical value of the corresponding decision). Their circulation must also be monitored so that some kind of control system built into the cryptocurrency itself performs the following functions:
Tracked the transaction history with each unique value
responded to the emergence special database of “doubles” (i.e. unauthorized emission);
blocked transactions in case of “doubts”.
Anything electronic is extremely easy to counterfeit. Any computer does this by simply copying every bit. Therefore, it was quickly understood that in order to ensure the genuine uniqueness and authenticity of virtual “money signs”, total control over all transactions in the system was required.
This is the kind of permanent control system
That blockchain pay attention to filters: it would be great if you could match the filter results to your suggestions technology provides – tracking and verification of each transaction, information about each of which forms a block. Blocks are written sequentially, forming a chain. And this entire chain is “attached” to the solution-value of the cryptocurrency coin, which is called the “block header”. And each such header contains such chains.
So, blockchain – what is it in simple aero leads words from the position of the block header, it is its security system, ensuring its uniqueness.
