This is a digital asset designed to be used as a medium of exchange. Obviously, this is a substitute for money. However, it uses strong cryptography to secure financial transactions, control asset transfers, and control the creation of additional units. All cryptocurrencies are either virtual currency, digital currency or alternative currency. It should be noted that all cryptocurrencies use a decentralized management system, as opposed to centralized systems of banks and other financial institutions. These decentralized systems operate through distributed registry technology that maintains a public financial database. Blockchain is commonly used.

What is a blockchain?
This is a growing list of records that are encrypted and secured. This list is called blocks. A blockchain is an open, distributed log that can be used to record transactions between two parties in a controllable, permanent way. In order for a block to be used as a distributed log, it is managed by an equal network that clings together to the new block validation protocol. When data is stored in a book, it cannot be changed without changing all the other blocks. Therefore, blockchains are secure in design, acting as an example of a distributed computing system.

History of cryptography
American cryptographer David Chaum has discovered an anonymous cryptographic electronic money called ecash. It happened in 1983. In 1995, David implemented it through Digikash. Digicash was an early form of cryptographic electronic payments that required user software to withdraw banknotes from a bank. It also allows you to assign specially encrypted keys before sending them to the recipient. This feature allows the digital currency to be erased by the government, the issuing bank or any third party.

2. Litecoin (October 2011)
3. Peercoin:
These three coins և are called by many others altcoins. The term is used to refer to alternatives to bitcoin or simply other cryptocurrencies.

It should also be noted that cryptocurrencies are exchanged online. This means that their use is mainly outside the banking system or other state institutions. Cryptocurrency exchanges involve the exchange of cryptocurrencies with other assets or other digital currencies. Ordinary fiat money is an example of an asset that can be traded in cryptocurrency.

Atomic exchanges
They refer to the proposed mechanism by which one cryptocurrency can be exchanged directly from another cryptocurrency. This means that in the case of nuclear swaps, there will be no need for a third party to participate in the exchange.
