What is web 3.0?

 The Web 3.0 era refers to the third generation of the Web, an intelligent and personalized Web. Web 3.0 is an intelligent web technology that allows computers to understand the contents of web pages and provide personalized information using semantic web technology.

The difference from Web 2.0 is the distributed storage of data and the utilization of blockchain technology. In Web 2.0, if the platform stored data in a central server, in Web 3.0, data is distributed and stored through blockchain. In addition, technologies and services such as blockchain, NFTs, and generative AI are expected to expand Web 3.0 experiences and adoption.

How will our lives change when the Web 3.0 world arrives? First of all, personal data ownership and security will be strengthened. In addition, a fair economic ecosystem in which creators and users are rewarded will be established. And, artificial intelligence will provide optimized information and services according to our tastes and needs.

Everyday use cases for Web 3.0 are numerous. For example:

Infrastructure services using Web 3.0 technologies1: Infrastructure services such as power grids, transportation networks, and communication networks can be operated more safely and efficiently through Web 3.0 technologies. For example, the power grid can be upgraded to a smart grid so that consumers and generators can trade electricity in real time, the transportation network can provide optimal routes in conjunction with autonomous vehicles, and the communication network uses blockchain to secure data. and privacy protection.

Content services using Web 3.0 technology: Content services such as music, movies, and games can be more fairly compensated by creators and users through Web 3.0 technology. For example, music is issued as an NFT so that creators can receive copyright fees directly, movies are shared through a P2P network rather than a streaming platform so users can enjoy them at a low price, and games are expanded to the metaverse so that users can enjoy their own You can create and trade your own characters and assets.

Search services using Web 3.0 technologies: Search engines can use Web 3.0 technologies to understand the content of web pages and provide personalized information. For example, a search engine can provide services such as preferentially showing information related to a user's hobbies or interests, enabling a user to search in natural language as if asking a direct question, or providing a summary of only the information the user needs. can

Here are the advantages and disadvantages of Web 2.0 and Web 3.0.

Advantages of Web 2.0: Users can read and write content, interact and collaborate through platforms such as social networking, blogs, and wikis. In addition, dynamic and diverse web services can be provided by utilizing technologies such as cloud computing and AJAX.

Disadvantages of Web 2.0: User data and privacy are weak, and giant platform corporations can monopolize and censor data and profits. Also, it is difficult for computers to understand and analyze the content of web pages.

Advantages of Web 3.0: Users can not only read and write content, but also own it, and creators and users can be fairly compensated through technologies such as tokens and smart contracts. In addition, intelligent and customized web services can be provided by utilizing technologies such as artificial intelligence, block chain, and IoT.

Disadvantages of Web 3.0: Low compatibility with existing Internet infrastructure, learning and adaptation to new technologies and regulations. In addition, the responsibility for security and privacy is placed heavily on users, and the risk of crimes such as hacking and fraud may increase.

Many challenges and barriers remain for Web 3.0 to become popular. For example, we need a UI/UX design that makes it easy to access and use Web 3.0 technologies and services1. It is also important to ensure the security and reliability of Web 3.0 and to resolve legal and ethical issues4.

It is not known exactly when Web 3.0 will become popular, but many researchers and developers are currently working to implement it13. As a new paradigm of the Internet, Web 3.0 is expected to bring many changes and innovations to our lives.
