Web3.0 suddenly became popular at the end of 2021. At the hearing of the US Congress, a sentence "How do we ensure that the web3 revolution takes place in the United States" attracted everyone's attention to Web3.0, and then Mask's tweet "Has anyone seen web3.0? I haven't found it" pushed the discussion on Web3.0 to a climax.

Even this word was rated as the annual hot word of science and technology by Reuters.

But what is Web3.0? To answer this question, we need to start with Web 1.0 and Web 2.0.

The World Wide Web, also known as the World Wide Web, is a global, dynamic interactive, cross platform distributed graphic information system based on hypertext and HTTP. It is a network service built on the Internet, which provides a graphical and easily accessible intuitive interface for the browser to find and browse information on the Internet. The documents and hyperlinks in it organize the information nodes on the Internet into a network structure that is interrelated with each other.

Web 1.0 is about getting and reading information. Web 2.0 is about reading, creating, sharing, and interacting with users. Web 3.0 is the third generation of the World Wide Web, a "decentralized" network running on the "blockchain" technology.

Web1.0 era

Web 1.0 is the first stage of the development of the World Wide Web. Roughly from 1991 to 2004. In the era of Web 1.0, there are only a few content producers, and the vast majority of users are content consumers. Personal web pages are very common, mainly composed of static pages hosted on the Web server running ISP or free Web hosting service.

Web 1.0 is a content distribution network (CDN) that can display information on websites. It can be used as a personal website to charge users according to the pages they view, and has a directory that enables users to retrieve specific information.

These pages are mainly linked together by hyperlinks, mainly text, without any visual effect, and cannot interact with anything in any important way. In essence, the early Internet was basically just a huge e-book repository.

The four design elements of a Web 1.0 site include:

Static page. The content is provided by the server's file system. Pages built using server-side containment or Common Gateway Interface (CGI). Frames and tables are used to position and align elements on the page.

In the era of Web 1.0, the main products are search engines and portals. You can easily find any content you want.

Representative products: Yahoo, Google, Sina, Sohu, Netease, Baidu.

Web2.0 era

In 2004, Tim OReilly and Dale Dougherty held the first Web 2.0 conference (later known as the Web 2.0 Summit), and the word "Web 2.0" became popular, which was created by Darcy DiNucci in 1999.

Web 2.0 era highlights the content, usability and interactivity created by users. Web 2.0 is also called participatory network. It does not modify any technical specifications, but optimizes the design and use of web pages. It allows interaction and collaboration in user conversations.

Web browser technology was developed in the era of Web 2.0, using AJAX and JavaScript frameworks. AJAX and JavaScript frameworks have become very popular methods for creating Web 2.0 sites.

Five main features of Web 2.0:

Free classification of information allows users to centrally retrieve and classify information. Respond to the dynamic content entered by the user. Use assessments and online comments to flow information between website owners and website users. Develop APIs to allow self use, for example through software applications. Web access leads to different concerns, from the traditional Internet user group to a broader user group.

The Most Important in the Web 2.0 Era Its application is social network, in which people can share their views, ideas and experiences. Users are not only users of the software platform, but also participants of the software platform.

Web3.0 era

According to the 2021 Global Internet Phenomenon Report released by Sandvine, a network monitoring company, Google, Meta, Netflix, Amazon, Microsoft and Apple generate more than 56% of global network traffic, and their traffic in 2021 accounts for more than all other Internet companies combined.

Today's Internet world is in essence a situation of co governance by these technology giants. They control user accounts, privacy, and interaction, and shape the order of the current Internet world.

The core of Web3.0 is no longer about speed, performance or convenience, but about "control". Web3.0 is a series of technologies aimed at reconstructing Internet control, which is a rebellion against the current Internet world.

Tim Berners Lee, the inventor of the World Wide Web, initially called Web 3.0 the Semantic Web and envisioned an intelligent, autonomous and open Internet that uses artificial intelligence and machine learning to act as a "global brain" and process content conceptually and contextually. Compared with Google's existing engine model, it builds "world information" in a more reasonable way.

It's networked Executable In this stage, computers can interpret information like humans, and then generate personalized content for users.

Main functions of Web 3.0:

Semantic Web: not only understand keywords and data, but also understand content such as pictures, videos or audio, as well as more complex associations between products, locations and specific behaviors. artificial intelligence: Combining this capability with natural language processing, in Web 3.0, computers can distinguish information like humans to provide faster and more relevant results. They become more intelligent to meet the needs of users. 3D graphics: 3D design is widely used in Web 3.0 websites and services. Museum guides, computer games, e-commerce, geospatial environments are all examples of using 3D graphics. Connectivity: With the help of Web 3.0, information is more closely linked due to semantic metadata. As a result, the user experience evolves to another level, leveraging all available information. Everywhere: Content can be accessed by multiple applications, each device is connected to the network, and services are available everywhere. DLT and Smart Contract: With the help of DLT, we can have a database that can hardly be cracked, from which people can obtain the value of the content and things they can virtually own. This is a kind of technology smart contract that realizes the untrusted society through integration. It does not require an intermediary as a guarantor to make the contract happen for a specific reason based on the data of the DLT. It is a powerful tool that can make the world a better place and create more opportunities for everyone on the Internet.

Differences between Web 1.0, Web 2.0, and Web 3.0

Web 1.0, Web 2.0 and Web 3.0 all have their own uniqueness, and they have completely changed the network world in their respective times. Web 3.0 is on the cusp of a storm, full of controversy and divergence What should it look like? What are the specific landmarks? We are looking forward to the new world of network.
