Cryptocurrency (or cryptography) is a controversial digital asset designed to function as a cryptographic medium of exchange to protect your transactions, additional monitor units and transfer of 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.

The decentralized control of each cryptocurrency works through a blockchain, which is the basis of public transactions, which functions as a distributed ledger.

Formal definition

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

• The policy determines whether new units of cryptocurrency can be created. If new units of cryptocurrency can be designed, the system identifies the circumstances of the source 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 transactions to be carried out in such a way that the owner of the cryptographic unit changes. A statement transaction can only be issued by an entity proving the current owners of these units.

• The ownership of cryptocurrency units can be shown exclusively cryptographically.

Review

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

As of May 2018, there were more than 1,800 crypto-transparent specifications. The cryptocurrency system, security, integrity and balance records are maintained by a community of mutually suspicious parties, called minors, who use their computer to confirm the time of the transaction by adding it to the registry according to a specific timestamp scheme.

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

cash in hand, it can be harder for the police to catch crypto. This problem comes from the use of cryptographic technologies.
