Over the past ten years or so, the lockdown has been established as one of the main technologies of our time. It's a computer process behind cryptovals like bitcoin. But many articles in major newspapers talk about it without explaining what it is. In this article, we look at the definition of the blockin and how it works, but first let's take a little historical tour.
Blockchenes and kryptos until bitcoin appears.
Bitcoin was not born with the creation of the famous Bitcoin cryptoval in 2009, and it was David Chaum, a graduate student at the University of California in Berkeley, who laid the foundation of this technology in 1982 in his thesis, "Computer Systems Created, Supported and Approved by Mutual Untrusting Groups." Then, in the 1990s, an American cryptologist launched the first virtual currency.
Other cryptovals were invented before the end of the millennium, such as Bit Gold and B-Money. These two examples remain at the project stage, but inspire the mysterious Satoshi Nakamoto to create Bitcoin. It is unknown who is behind this pseudonym, but this man published a paper in 2008 describing the principle of bitcoin. A year later Satoshi Nakamoto launched a future star cryptizing.
Institutional definition of blocking technology
The joint information mission of the National Assembly on the use of blocking and other registry certification technologies provides a definition of the block in the 2018 report: "".
More detailed explanation of the blockage
A classic example of banks
Before the locker came in, the database was usually held by one entity. If you take the example of a bank, the contents of accounts or transactions are recorded on a computer server. The client can check his account balance by contacting the bank. Then the bank provides him with information according to the database. If he withdraws the money, the bank changes the database, and the client knows nothing more. The information in the register is centralized and not transparent in the sense that you don't know who owns the receivables.
Changes due to block-chamber technology
Block
Thanks to blocking technology, the registry is decentralized; there is not one server on which the database is stored, but many that are not connected except with the block, and the information is common: everyone can read the transaction history from the moment the block is created.
Benefits of block-chamber
In contrast to the example of a bank, which is made up of database divisions, the locker takes over by means of automated computer protocols, thus achieving real savings in operating costs, labour costs and transaction costs; the system is safe, because the verification of transactions is done through a network of independent computer servers; speed is also an advantage, because transactions take place in a matter of seconds; it is also far from being limited to cryptivates; its application is numerous and sometimes even surprising.
