Over the past few years, the opinion has been increasingly expressed that the current model of the Internet is obsolete and needs to be revised: corporations greedily collect user data, censor and know more about users than their next of kin. Influencers and industry leaders offer their ideas for shaping Web 3.0 and talk about how to make the Web better and safer. In this article, we will look at the history of the development of the Internet, highlight the distinctive features of each era and analyze what is predicted for us in the near future. First, it is important to note that the so-called versions of the Internet have evolved over time, gradually. There was no clear historical transition from Web 1.0 to Web 2.0. It is likely that humanity will not be able to immediately switch to Web 3.0 either. The web has evolved, websites have started to add new features, the Internet has come to new concepts, and users have noticed that they are already using a completely different infrastructure. At this stage, they described the ideas of the new era, as well as summed up the results of the past. 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 can be used to identify 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.
Web 3 is what the modern world needs. I really love this technology because it gives a huge number of opportunities and space for hiring in the world of cryptocurrency! The most important thing is that I am not alone, but we are a whole community of united people who prefer this technology.
