About bankers say bankers, ministers and hackers. This technology is able to change the world, as did the Internet. Experts in this field are estimated to be 3-4 times higher than other IT specialists, and the world-famous banks in their development strategies gave top priority to studying the blockade. According to experts, by 2027 this technology will be used to store about 10% of world GDP.

1, Blokchan ... Somewhere I've heard it Yes, this technology underlies the work of the crypto currency, for example, bitkoyna. But this is just the tip of a giant iceberg. We will explain everything, as they say, for the humanities. Blockchain (blockchain) - built in a certain way the chain of all transactions that have ever been committed (or operations).

I'm sorry, what?.

Blocking is a way of organizing and storing data on transactions, contracts, transfers, and so on.. In the blockroom you can store data on loans and deposits, on taxes, on registration of citizens at the place of residence and even violations of traffic rules.

And why all this can not be stored in a traditional database? Why complicate?.

The advantage of blocking against traditional databases is that the data is not stored on any particular physical medium or in the cloud. There is no centralized supervisory authority. The data is distributed among all users of the system, no matter how many, ten, one hundred or one hundred thousand. In a sense, on the contrary, everything has become much easier and more transparent, because any participant will be able to see the current version of the register for all transactions (changes in the merger agreement of the two banks, for example).

Is it all about the way information is stored?.

Of course not. The main plus blockage is that all actions (transactions) in the system occur without intermediaries. This means, without notaries, banks, government agencies, which in the ordinary world confirm the authenticity of the transaction. To put it more simply, with the arrival of the block-man, these intermediate stages will simply not be necessary: ??you can not certify a copy of the passport from a notary, do not contact the insurance agent, and work directly with the insurer bank, your company will no longer be disturbed by auditors and controllers. Because each transaction is transparent and accessible, all changes are fixed in the chain by records that are attached to each other in turn. Procedures are greatly simplified, and therefore cheaper. The chain also excludes any forgery and kickbacks: if the current state of records is entered into a chain, then it can not be canceled.

Can you give a concrete example?.

Imagine that you are getting a job, and you need to collect a certain package of documents: address information, a certificate of non-conviction, a certified copy of the passport and fluorography, although you already passed it in the clinic six months ago. We see that you need to at least go to the PSC, to the notary and to the clinic for confirmation with a doctor's seal, and here in the PSC require some additional information, say, from the tax. That is, you need to prove to the employer the authenticity of all your documents with official seals and signatures. Now imagine that there is no need to go anywhere and, moreover, no papers are also needed. Because all these structures are united in one transparent network in which each participant owns all the necessary information, it is distributed among all, and trust is established between all nodes. This is a very simple example on the fingers. Now imagine what opportunities for international trade, business, banking systems, government, education and health.

Is it possible to hack such a system?.

The developers claim that they do not yet know of any successful attack on the blockade. The network is arranged so that when an attempt is made to hack one node, all others will receive a signal about it, and changes in the system will be immediately blocked. The stability of such a system is many times higher than that of a centralized database with a conventional server.

Well, are there any downsides to the blockade?.

This technology has so far been little studied and is still in its infancy. With private use, everything is clear: you buy goods, pay in digital currency, you do not need a bank to transfer, you are anonymous. Easy, fast, without intermediaries. But not every business process can be screwed to a blockage, so it is very important to be cautious about implementing such a system, and it is better to take a waiting and observant position. In addition, the amount of data in large corporate networks is growing very rapidly, information is copied in parallel to all nodes of the system. And this is the limit, after which the system ceases to be easy and fast.

Does the blockade of danger itself, if you look back on the Internet?.

Researchers from the American RAND Corporation published a report on the need to combat bitocans. They assure that the crypto-currency can become a threat to national security, t. Bitkoyn is a black market currency through which drugs and weapons pass. Nobody controls bitcoin, bitkoyn does not belong to anyone, anyone can register in the system. Opponents of the crypto currency say that this is one of the ways to launder money and support international terrorism.
