What is cryptocurrency?

Cryptocurrency (or Cryptography) is a controversial digital asset designed to act as a cryptographic medium of exchange to secure your transactions, additional monitor units and transfer assets. Cryptocurrencies are a type of digital currency, alternative currency, and virtual currency. Cryptocurrencies use decentralized control instead of a centralized electronic money system and central banks.

Decentralized control of each cryptocurrency works through a blockchain that underpins public transactions that act as a distributed ledger.

Formal definition

According to Jan Lansky, cryptocurrency is a system that meets four conditions:

• Policy determines whether new cryptocurrency units will be created. If new cryptocurrency units can be designed, the system determines the terms of the resource with the ownership of these new units.

• If two different instructions are entered to change the purchase of the same cryptographic units, the system executes at most one of them.

• The system allows operations to be carried out in such a way that the owner of the cryptographic unit is changed. The withdrawal operation can be issued only by the organization that proves the current owners of these units.

• Ownership of cryptocurrency units can only be shown cryptographically.


Decentralized cryptography produces the entire system of cryptographic services at a rate determined at the time of system creation and is publicly known. In centralized banking and economic policies, such as the Federal Reserve, administrative committees or governments control the money supply by printing units of trust funds or requiring additional digital ledgers. In the case of a decentralized cryptocurrency, governments or companies cannot produce new units, but they are not compatible with other companies, banks or institutions that have property values. The basic technical system based on decentralized cryptocurrencies was created by a group or individual known as Satoshi Nakamoto.

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

Most cryptocurrencies are designed to gradually reduce the production of this currency by limiting the total amount of coins that will be in circulation. Compared to common currencies held or held by financial institutions

cash in hand, police cryptocurrency can be more difficult to hold. This problem arises from the exploitation of cryptographic technologies.
