We are constantly talking about cryptocurrencies, interested in trading and decentralized applications. All this is available to us thanks to blockchain technology. But do we know what they are and how they are actually used? Perhaps for many people, especially those who are new to the world of decentralized digital assets, it can be difficult to understand all the nuances: blockchain seems complicated and incomprehensible. In fact, its basic concept is quite simple!
That’s why today we’re going to break down the basic facts about blockchain technology in simple and easy to understand language!
Let’s start with the history!
In fact, the technologies of distributed computing and decentralized information storage were introduced back in the 90’s. But nobody knew about blockchain back then. The term “blockchain” itself became known only recently, in 2008 – when a certain Satoshi Nakamoto showed how these technologies could be used to organize a new financial system.
📌 Blockchain is a special type of database. It differs from a typical database in the way information is stored: blockchains store data in blocks, which are then combined into a chain. In its structure, a blockchain can be compared to an infinitely long metal chain in which the links cannot be broken or swapped.
How does it work?
🔸 The blockchain records all the data about the transactions being realized. However, it should be understood that the word “transaction” does not equal a money transfer and, in this case, refers rather to the way information is processed within the network. As new data enters the blockchain, it is entered into a new block. Once the block is filled with information, it is linked to the previous block, resulting in the data being chained together in chronological order. Note that this data cannot be changed or deleted.
What information can be stored in a blockchain?
🔸 Various types of information can be stored in blockchain, but so far the most common use is transaction recording.
Where is blockchain technology already in use?
The most common application of these technologies is in the field of cryptocurrency, but that’s not all you’d think. Other areas in which blockchain technology is already being used today are:
✔️The field of copyright protection
✔️Voting on the Web
✔️Confidential messaging
✔️Computer games
✔️Preventing DDoS attacks
What are the prospects for blockchain technology?
🔸 Of course, such an innovative and feature-rich technology could not go unnoticed by modern IT corporations. New ideas for blockchain applications keep emerging in the market. Personally, we believe that blockchain technology has a big and interesting future.
