Cryptocurrencies (digital cryptographic currencies) is an innovative, distributed accounting system that collects and stores information about hold in contract units. Hold is related to individual system nodes, the so-called wallets, in a way that ensures full control over a certain
cryptocurrency wallet only to the holder of the corresponding private key. If such a holder expresses the readiness to make a transaction it takes place electronically - directly between them and between a particular trade partner. Every unit of cryptocurrency has a unique code containing pieces of information that prevent its copying or unwanted respending. Most cryptocurrencies are distinguished by the fact that they do not have any supervisory body (regulating or controlling them) that could decide, for instance, about increasing their supply with potential decrease in value. Their decentralized character means that virtual assets gain in importance and gain in popularity, having at the same time the trust of various communities. The turnover in cryptocurrencies takes place only electronically - directly between a minimum of two users (the so-called peer-to-peer technology (P2P), that is a model of communication in a computer network, ensuring that all of the hosts have equal rights, which distinguishes it from client-server architecture), without the participation of any kinds of banking systems or other supervisory institutions. There is no entity that would be able to control transactions, and therefore it is impossible to "block" our account. One of the most important and one of the most popular cryptocurrencies is Bitcoin, holding from the very beginning the position of the leader as its market capitalization guarantees it an absolute primacy in this industry. Other important digital assets include: Ethereum, Ripple, Litecoin, Monero, or Waves, as well as many other alternative currencies that enjoy the unfailing trust of network users.
