Despite the fact that the blockchain technology is often
associated with digital or virtual currency schemes, payments and
financial services, its scope of use is much wider. In practice,
blockchain is already used in various sectors (e.g. trade and
commerce, healthcare, public administration, logistics, banking, etc.).
It should be noted that cryptocurrency is the first well-known
application of the blockchain technology, which formed the basis of
the cryptocurrency market and resulted in the whole variety of
cryptocurrencies. At the same time, it can be noted today that
blockchain has clearly outgrown the cryptocurrency context and, as a
technology, it can be applied in many areas of social life.
Since the emergence of the first virtual currency in 2009, the
topic of cryptocurrencies and blockchain has been studied by various
international organizations and state institutions, each of which
approached it differently. The fundamental documents for clarifying
the essence of the terms under consideration are official publications
of international regulatory and supervisory bodies in this area.
The European Central Bank (ECB) classified cryptocurrencies
as a subgroup of virtual currencies. In its report on virtual currency
schemes in 2012, the ECB defined such currencies as a type of
unregulated, digital money, which is issued and usually controlled by
its developers, and used and accepted among the members of a specific
virtual community.
The ECB further clarified that three types of virtual currencies
can be distinguished depending on the interaction with traditional
currencies and the real economy:
1) virtual currencies, which can only be used in closed virtual
systems, usually in online games;
2) virtual currencies that are unilaterally linked to the real
economy: there is a conversion rate for purchasing currency (with
traditional money), and the purchased currency can subsequently be
used to purchase virtual or real goods and services;
3) virtual currencies that are bilaterally linked to the real
economy: there are conversion rates both for purchasing and selling
such currency; the purchased currency can be used to purchase both
virtual and real goods and services [1, p. 13–19].
