The rapid development of blockchain technology will become a catalyst for the growth of innovation in all spheres of human life, thus creating the basis for the emergence of a self-determined identity. For example, Web 3 is expected to completely change the work of social networks. Using blockchain, it will not be possible to limit social platforms: anyone would join regardless of geographic restrictions. The evolution of Web 3 technologies and the associated expansion of decentralization pave the way for the future, where people will pay more attention to the development of their personality, manifesting in various activities, which will lead to the creation of social well-being. Therefore, it seems that Web 3 is the branch that would mature earlier than other existing options. Decentralized exchanges, the key roadmaps to which is customers’ trust and investment needs, tend to become more popular as they provide an unhindered exchange of user experience without concerns on hacks or transparency. It also means the prevention of centralized authority and conflict of interest on the part of an owner.
Cryptocurrencies, in many respects, return to humanity what is called sound money, the role of which gold played earlier and now continues to play. This is honest and trustless money, which is not centralized, and it can be created by everyone who wants to invest in their extraction, yet their number is limited. They cannot be mined indefinitely, but their devaluation and inflation are impossible due to physical limitations. Sound money technology would promote the protection of user privacy, and large corporations and organizations would lose the power to influence others. The anticipated impact of open finance is that it would combine the cryptocurrency sphere with the world of financial assets, including low-liquid securities owned by hedge funds, private equity funds, et cetera. Accordingly, it would be possible to buy, sell, or exchange security tokens, which are not traded anywhere else. One would trade illiquid securities that can be sold at other sites, but it is difficult because of the long implementation periods, outdated trading rules, and other problems.
