What is cryptocurrency?

Cryptocurrency (or cryptography) is a controversial digital asset designed to serve as a cryptographic medium of exchange for your transactions, additional monitor units and asset transfers. Crypto values ​​are a type of digital currency, alternative currency and virtual currency. Cryptocurrencies use centralized electronic money systems and decentralized controls instead of central banks.

Decentralized control of each cryptocurrency operates through a blockchain, the basis of public transactions, which serves as a distributed record.

Formal definition

According to Jan Lansky, crypto can be a system that meets four conditions:

• The policy determines whether new cryptocurrency units can be created. If new cryptocurrency units can be designed, the system identifies the source situation with the ownership of these new units.

দুটি If two different instructions are entered to change the purchase of the same cryptographic unit, the system performs at most one of them.

The system allows transactions to be managed in such a way that the owner of the cryptographic unit is changed. A statement transaction can only be issued by an entity proving the current owners of this unit.

মালিক Ownership of cryptocurrency units can be shown exclusively cryptographically.


Decentralized cryptography collectively creates a complete system of cryptographic services at a speed defined during system building and is universally known. In central banking and economic policy, such as the Federal Reserve system, governing bodies or governments regulate money supply by printing units of trust funds or by requiring complementary digital books. In the case of decentralized cryptocurrency, governments or companies cannot create new units, and yet they are not compatible with other companies, banks or entities that have asset values. The initial technological system, based on decentralized cryptocurrency, was created by a group or individual known as Satoshi Nakamoto.

As of May 2018, there were over 1,800 crypto transparent specifications. The system of crypto-currency, security, integrity and balance of records is maintained by a community of mutually suspicious parties called minors who use their computers to confirm the time of the transaction, adding them to the registry under a specific time-stamp scheme.

Most cryptocurrencies are designed to gradually reduce the production of this currency by limiting the total amount of currency that will be in circulation. Financial institution or maintenance compared to ordinary currency

With money in hand, it can be difficult to catch a police crypto. This problem comes from the exploitation of cryptographic technology.
