Cryptocurrency is the result of computer calculations; electronic registers storing information about how much a user has a cryptocurrency and where he transfers it. Cryptocurrency is stored in special electronic wallets.

With the advent of the Internet, there have been periodic attempts to create digital currency around the world. However, no one trusted these projects - and they did not gain popularity. They were too easy to fake.

The first cryptocurrency, Bitcoin, was able to solve this problem using blockchain. This system has been compared to a large book containing all the records of what is happening with the cryptocurrency. And every bitcoin owner has an independent, but identical copy of this book to others.

The entries in all the books are true and the same. Neither banks, nor the government, nor the creator of the cryptocurrency can fake these records. In other words, there is no single controller in the blockchain, the system is controlled by many participants. The system, built on mathematical calculations, protects digital currency from counterfeiting or hacking.
