Fortunately, the tendency to return to the origins, to the original purpose of the Internet, is developing again. This idea is called "Decentralized Web", or Web 3.0, and involves the creation of services, the operation of which is not subject to some "central" organization.The concept of a decentralized web implies a future in which services such as communication, finance, publishing, social networking, search, archiving, etc. are not provided by centralized platforms controlled by one organization or another, but are managed by people, that is, by a community of users . Responsibility for the operation of the service also becomes a matter for the community.
