Web2 vs Web3

The second version of the Internet addressed this major shortcoming of the first version and provided the user with the means to interact with sites and generate a huge amount of content. With the wide spread of cell phones with built-in cameras, anyone could easily create visual content. And the emergence of social media like Faceboock or Instagram enabled quick and easy sharing of text and visual content. In addition, a huge amount of software allowed to create games, music, videos and other apps.

● Tagging. A switch from pre-designed categorization of content to tags that can be set by users themselves. Thus, content categorization is determined not by the site creators, but by its visitors.
● Expanded user experience. The first version of the Internet featured mostly static pages. Introduction of such technologies as Ajax, HTML5 allows to interact with the visitor and add dynamic videos to pages.
● Collaborative content interaction. Modern technologies make it possible to share, edit and create new content.
● Site interaction. The ability to leave comments and rate content, thus influencing its ranking, is probably the most important feature of Web2.0.

The second generation provided visitors with lots of advantages. These are the highlights:
● 24/7 accessibility from anywhere in the world.
● A huge amount of content.
● Accessibility of information. Search engines make finding what you need easy.
● Various formats for presenting information: if a manual is hard to read, most likely, you can watch a video.
● Search engines give access to both old and new data.
● Multilingual search and easy translation into the language you need.
● Ability to share content with users all over the world.
● File and document sharing.
● Moving shopping almost entirely to the Internet. You can buy groceries or clothes by delivery or order the services you need with only a phone connected to the Internet.

Web2 offers plenty of advantages. If everything was perfect, no one would strive to create Web3. Now, users are beginning to notice more and more disadvantages of the second version of the Web, other than the benefits. These are the main ones:
● Centralized management over the entire network.
● Obtaining inaccurate information. Content creators can intentionally present information distorted or misleading, which leads to incorrect perception of the content by visitors.
● Many services and data cannot be accessed without registering and providing some personal information (e-mail).
● Developed fraud, spam, malware.

The limitations of the second version of the Internet and the emergence of new technologies encourage the creation and transition to web3. The third version is based on sophisticated software tools like artificial intelligence. Web3 aims to offer users better reliability, speed, features. All this already exists in Web2. So, what’s the point?

● Machine intelligence. By using artificial intelligence, computers learn to understand content not based on keywords, but the way humans do — based on meaning. Such understanding will lead to improved search results and provide the most relevant content possible.
● Information interconnection. The interaction between computers and the user allows for greater connectedness of different information, thus providing the user with all the information available.
● Omnipresence. Through multiple gadgets with Internet access, users can access content anytime, anywhere.
● This makes it possible to visit museums, play the most realistic games, use augmented reality gadgets, etc.

Web3's decentralized structure is its biggest advantage or value to its users. In addition, Web3 will provide:
● Increased privacy. Web3 prioritizes security and privacy over surveillance and control.
● Security. Blockchain technology will make the third version of the Internet more secure. Decentralized applications will be much harder to hack. But even in the event that it happens, all the attacker's actions will be recorded in a distributed registry.
● Universal accessibility. There are many different devices connected to the Internet. Connectivity will be available anywhere.
● Improved accuracy and personalized search results. Thanks to artificial intelligence and user interaction, all available data will be used.

● Transactions in Web3 take longer to complete because they are decentralized. Changes in status, such as payment, must be distributed across the network.
● No integration into modern web browsers makes Web3 less accessible to most users. Hard-to-understand processes are intimidating for many average users.
● Cost — most successful decentralized applications put very small parts of their code on the blockchain because it is expensive.

Centralization and decentralization constitute the most central difference between the two versions. In Web2, the web service code is stored on the company's server. The company itself makes decisions regarding the program's development. The database storing the actions of users using the service is also located on the company's servers. This all leads to a situation where a single company controls the entire service. The company may interfere with the service and change any data. No one can check anything without the consent of the company. Any digital item purchased on the service does not belong to the user, but remains the property of the company.

In Web3, program code is stored in a decentralized fashion. Blockchain technology makes it impossible to tamper with the data and fix anything in secret. The distributed registry makes it possible to obtain data and verify its integrity. The use of non-named NFT tokens allows the ownership of digital assets.
Since web3 technologies have more prospects, the market is developing and career courses are emerging so that everyone can delve deeper into her work and build their career in the promising Web3 market.

Having considered the key advantages of the second and third generations of the Internet, we can summarize this information:
