What is Blockchain?

The simplest definition of the blockchain in Turkish, is a digital cash register with a time stamp which is not connected to any central system, providing follow-up of encrypted transactions, followed by a distributed database in which data is approved by registered users in the system, as understood from its name, it is a chained model that is lined up one after the other.

In any transaction, for instance in car sales, information such as the identity of the buyer and the seller, the status of the car, etc. are encrypted and a block is formed. This information block is distributed to all users in the system. This information block, which is verified by unanimous vote of users, is added at the end of the previous block. The most important feature of Blockchain technology is that it has a decentralized verification system. That is, there is no need for a third party (notary) between the person selling the car and the person purchasing it.

A Machine of unique Security and Transparent Structure

These transactions are sent to all users in the system and everyone has the same information. Anyone in the system can examine all the blocks of information that have accumulated up to this time and go through it. However, since the encrypted identities of the parties are used, it is unknown or unpredictable who the buyer and the seller are. In this respect, Blockchain technology allows parties to remain anonymous.

Potential areas of usage
