The main concepts of Web 3.0 were outlined by Netscape CEO Jason Calacanis. First, it is important to note that, as before, no one has a clear idea of ​​​​what the next round of Internet development will be like. Secondly, Web 3.0 is at an early stage, so only initial ideas about the technology are available so far. However, Calacanis published his vision for the future back in 2007 and believes that Web 2.0 should create a new space that solves major problems.

The leader considers the depreciation of resources and services to be the main problem: the relative ease of creating sites has influenced the emergence of monotony. Tim O'Reilly supported Calacanis' ideas at one time, and also noted that Web 3.0 should go beyond the usual understanding of the Web and begin to "interact with the physical world."

Defining characteristics of Web 3.0:

decentralization: data will no longer be stored on single servers, but distributed among users. The necessary computing will move from data centers to laptops, smartphones and smart gadgets of users. Currently, there are technologies to achieve this, but there is no single decision on which one will underpin the "new Internet";

AI and Machine Learning: Intelligent algorithms will not disappear from the web and will continue to help users find the content they need. Some researchers note that in the future, AI could be used to detect paid comments on marketplaces, which will help create more transparent services;

openness: the software will be predominantly open source, which will allow you to thoroughly understand how the tools are arranged and how they interact with the user;

freedom: it is expected that censorship on the Web will be abolished, and everyone will have the opportunity to publish any content, the role of moderation will be taken over by the community, not corporations;

omnipresence: experts suggest that in the era of Web 3.0, the Internet will be almost anywhere, and IoT devices and smart gadgets will become distributors;

semantic web: the machine does not understand natural language queries well and is still often wrong. To improve this process, they plan to use the technology of the semantic web, when it is possible to receive information of the type “object - type of relationship - another object” from the Web and build logical connections based on this data.

In addition to key differences, enthusiasts and experts predict other changes. Firstly, the method of authorization in services may change to a single layer, which will be the key to all resources on the Web. Something similar has been implemented now: using a Google or Facebook account, you can enter almost any site, but in the case of Web 3.0, a single account can become both a wallet and a banking application.

Secondly, the Internet will become more democratized and the usefulness of content will be determined by Decentralized Autonomous Organizations (DAO), which will be large companies and services, and DAO participants will have the right to vote and make decisions important for the content and the organizations themselves. In other words, it is something like a global system of karma.

Now the ideas of Web 3.0 are still ideas and cause more questions than understanding. In addition, the concept is often promoted by crypto investors and NFT enthusiasts who reduce everything to a new type of income.
