Cryptocurrency is a very valuable and sought-after asset. Presently, the world comprises more than a thousand of various cryptocurrencies, the majority of which propose to get their own crypto-coins. Thereafter, the same cryptocurrencies become rather liquid assets at cryptocurrency exchanges, where one can trade in them. Classical investment banks and stock exchanges start paying a serious attention to cryptocurrency exchanges, and this is attested by appearance of Bitcoin futures and by development by investment banks of their own cryptocurrency marketplaces.
But this means nothing but the following: cryptocurrencies have asserted themselves in all possible ways and are now acknowledged by official classical establishments. Hence, this, in its turn, will only increase the speed of cryptocurrencies development and their market share.
Blockchain is a notion that became popular due to the crypto-market boost. It is tied to innovative data-processing techniques that ensure the integrity, transparency and security.
The blockchain technology became widely used in different spheres. Its most well-known use is in the cryptocurrencies (for instance, bitcoin and Ethereum).
Blockchain is a powerful tool that can change a great deal of spheres. It ensures the security, transparency and decentralisation, and this makes blockchain attractive for developers and users.
In the last year, the global cryptocurrency market has been growing rapidly. Their combined capitalization reached $2.3 trillion in December 2021. In the near future, blockchain technology and cryptocurrencies will become an integral part of our lives Cryptocurrency will be distributed everywhere. It will be interesting not only to a small circle of crypto enthusiasts, but also to the whole world. It will be possible to buy any goods with cryptocurrency coins.
Blockchain allows each network member to get access to the distributed database. Besides this, blockchain keeps not the data as such but the records of events (transactions), in their chronological order. The authenticity of all new records is checked: the majority of network members must confirm such records, so that they may be entered into the blockchain.
Blockchain may operate both within a public (open) network, which may be accessed by any user, and also within a private (closed) network, for instance, within a corporate network, if confidential data are used there. Private blockchain versions may specify different levels of access for users and different complexity of data encryption. The most well-known example of public blockchain are bitcoins and other cryptocurrencies. Corporations use blockchains both in the financial sphere and in other sectors.
