Web3.0, as the frontier of blockchain technology, was conceived as early as a decade ago. On the recent "2021 Web3.0 China Summit" held in Chengdu, Sichuan province, it has once again attracted public attention. Despite that, many people are still a stranger to Web3.0, without knowing what it is and what it does.

In order to better understand Web3.0, let's have a quick review of Web1.0 and Web2.0. Compared to its successors, Web1.0 was the earliest version of the Internet composed of web pages, on which the user interaction was limited to simple, passive content acquisition and query. People browsed the text and pictures on the website and could only see what the site presented.

However, with the rise of phenomenal applications such as Weibo and WeChat, we have entered the Web2.0 stage, where the introduction of Web applications opened up new horizons of human-computer interaction. At this stage, people can actively participate in the Internet content creation, communicate freely through network platforms, express their opinions, and use videos to record their lives. At this time, a variety of new cultures were born from it, which promoted the surge in the number of net users and the digital transformation of all walks of life.

However, Web2.0 is mastered by the technology giants after all. In Web2.0, giant companies are using users' data information for their own benefit, and there's nothing users can do to stop it. The personal information, behavior trajectory, and value hid in the series of digital information generated by users' content creation, participation, and interoperation on the Internet platforms are not owned by users themselves but stored on the servers of technology giants, ready to be used. Thanks to decentralization, the transition to Web 3.0 can solve the problems of data privacy.  Web3.0 will give control back to consumers, enabling them to manage their personal data on their own terms.

Of course, from the current perspective, although Web 3.0 is the inevitable trend of the technical development, it is still full of uncertainty, as no individual or institution can predict when it will be fully implemented.

Thanks to the rapid development of the 5G communication technology, we will hopefully live in a world of smart interconnection and the Internet of all things. The currently popular concept "smart home" represents the prototype of the Internet of Things - all home appliances are connected to the Internet and can be controlled through a mobile phone (yet there may be no mobile phone in the future, as it can be replaced by more advanced wearable devices).

The maturity of artificial intelligence is one of the signs of the Web3.0 era. If we have a highly intelligent robot in our home, then all of our information sources or interactions on the Internet can be enabled through dialogues with the robot.

The popularity of blockchain and the wide circulation of cryptocurrencies also herald the advent of the Web3.0 era. Web3.0 is built on the basis of blockchain and cryptocurrency, leading to user-controlled data ownership that guarantees data privacy and security. Since there is no centralized server, users will no longer have to rely on company-controlled transit agencies, thus solving the problem of personal data confidentiality. And due to decentralization, all data will be spread between devices so that people can access them freely, which will present a more user-friendly Internet world.

On the other hand, Web3.0 will also bring forward the integration of online interaction and people's lives. New technologies and concepts such as big data, cloud computing, artificial intelligence, Internet of Things, smart hardware, and blockchain that have been popular in recent years are all closely related to Web 3.0. Smart hardware and the Internet of Things will allow more devices to connect to the Internet to serve users' daily lives through interconnection. These are all possible technical upgrades that Web3.0 will bring us.

In general, Web3.0 can change the current power imbalance caused by the centralized network, and return the power of content creation to the hands of users. It can also change people's lifestyles, and make life more convenient through smart interconnection. A more user-friendly, transparent, and safer Internet world can be built by the implementation of Web3.0.
