Why is blockchain needed?

Our life is indissolubly related to money, data and documents. From it we have to contact with various mediators, that give out to us these money, documents and data, check up them, certify their authenticity, give out to the copy, check to authenticity of copy et cetera.

Thus вынуждают us to trust these mediators, although every now and again bankers hide with money of clients, notaries counterfeit testaments and agreements backdated, the employees of public organs and commercial organizations use official position in evil-minded aims.

Not having the opportunity to trust each other, we come running to the help of mediators that deserve no trust too. It was here remarkably, if there was a method to provide authenticity in our relations at the conclusion of transactions, execution of contracts, and also registration of rights and events!

Blockchain just and works out all these problems.

What blockchain?

Blockchain is technology of the reliable up-diffused storage of reliable records, on a large account, about whatever. For example, in blockchain it is possible to keep records about money orders. And in cryptocurrencies of blockchain just used for jigging of information about that, who, to whom and how many virtual money translated. But in blockchain it is possible to keep data about the given out credits, rights on property, violation of rules of travelling motion, marriages. In general, all, that can be written down on a paper, it is possible to write down and in blockchain with one only difference - in blockchain simply unreal to substitute or counterfeit records.

In order that understanding, how it succeeded to be obtained, is necessary closer to become acquainted with the very ingenious device of blockchain.

Device of blockchain

Blockchain - it, however difficult to guess from the name, chainlet of blocks of data, where every block is related to previous. A block is contained by the set of records. And new blocks are always added strictly to the end of chainlet.

However it is a very not simple chainlet that is built on three very important principles :

it is distribution; it is Openness; it is Security.

All users of blockchain form by itself the network of computers, on each of that the copy of data of blockchain is kept. It is ordinary complete copy of all blocks, but, in principle, it is possible to keep necessary on a concrete computer data only.

Due to it turning off or break blockchain is practically impossible, as for this purpose it is necessary to turn off or break all computers. While there is though one user, blockchain exists. Every FTU extends and strengthens this network. All computers are equal in rights thus, there are not organizers, moderators, inspectors and managers. Everybody is responsible for itself.

All data of blockchain - blocks and their content are open always and for all. you easily can read any block and see all records in this block. you can look a chainlet and watch the change of information. Thus, all data in blockchain are easily checked up, and, to you not necessarily to trust other participants of network, in fact you always can check them and get a reliable answer assuredly.

For the protection of data and users an encipherement is widely used in blockchain. Due to it you simultaneously get it would seem incompatible is an openness and authenticity at a complete mistrust to other participants and, maybe, even their evil-minded intention.

Simpler speaking, in blockchain any can see that someone has million. But here for whom he is concretely - can not know it any, while the proprietor of million will not give the special key to him, confirming the same, that he has million exactly.
