The Internet is indeed a shocking technology. From the first generation of Internet, our work and lifestyle have been completely changed. The rapid spread of information has made the whole world a global village.

After the emergence of Web 1.0, we have a search engine like Yahoo. Individuals can also set up websites to display their various information. Many people feel that they are enough, and even those Internet Co that are overvalued on the Nasdaq market even feel that the bubble is too big. So that in 2000, the Internet bubble burst. Netease, once listed on the Nasdaq market, faces the risk of delisting when its share price falls to 80 cents. However, after 2004, the arrival of Web 2.0 has completely changed people's view of the network. The Internet is no longer unique to professionals. Ordinary users can easily create and share content on the Internet as long as they have a mobile phone. Under these conditions, a new generation of Internet giants such as twitter and Facebook have emerged. Sit up and take notice of Internet Co's profitability. For example, Netease now has a share price of more than $100 and a P / E ratio of only more than 30 times. As for the businesses of Internet giants such as Tencent, Amazon and Alibaba, they are closely related to the lives of ordinary people.

So is there Web 3.0? When will Web 3.0 appear? When web 2.0 was proposed, people began to predict the possibility of Web 3.0.

You can also find entries about Web 3.0 on Baidu Encyclopedia. The entry is interpreted as follows: "Web3.0 is just a concept word created by people in the industry. The most common explanation is that the information in the website can directly interact with the relevant information of other websites, and can integrate and use the information of multiple websites through the third-party information platform at the same time; users have their own data on the Internet and can use it on different websites; it is completely based on the web and can be accessed by browser It can realize system functions that can only be realized by complex system programs; after user data audit, it is synchronized with network data. "

It seems that many speculations about Web 3.0 have not been generally recognized. However, many things always appear when people begin to be disappointed. An important technology has attracted the attention of Internet elites in recent years, which is "blockchain" technology.

When it comes to blockchain, people immediately think of bitcoin, and then "speculation" Speculative behavior. This has brought some negative effects on the block chain technology. After all, bitcoin is just an algorithm on the Internet. We now have many algorithms on the Internet, and countless App. Why do you have a trillion dollars worth of value in a program? What makes people feel that the bubble is too heavy? If we recall the collapse of the Internet bubble in 2000, Do you think there are some similarities between the two?

In fact, the core of blockchain technology is decentralization, using encryption algorithm to ensure the authenticity of identity, and the signed documents are unique and undeniable.

With this feature of blockchain, combined with various elements of online games, a brand-new concept "meta universe" is gradually formed

The concept of the meta universe comes from the novel avalanche written by American writer Niels Stevenson in the 1990s In this science fiction novel, the protagonist's real life is embarrassed, but he can live a very decent life in his own online world. Niels Stephenson believes that this is because there are two worlds. Everyone can switch his life back and forth between the real world and the virtual world. The concept of meta universe is formed.

However, people who have played online games know that there is a problem with online games. Although online games can make players more and more immersed in the game, the game account of players does not correspond to the players themselves one by one. In the whole game trading system, the tokens used also have no real value. Game designers can To inflate or deflate the Star Diamond token in a game scene at any time. This is very different from the interaction between people in the real world.

However, after using the blockchain technology, the cryptocurrency is issued in the game. This cryptocurrency has a limited number and is not controlled by the game manufacturer. Once issued, it has the same value as the real currency and has a fairly perfect trading function. This can be seen from the popular bitcoin. With this function, players can even side Play games to earn cryptocurrency, and then exchange it into legal currency in the real world, such as some NFT games.

In addition, after the use of blockchain technology, everyone's personality can be gradually enriched. These personalities are unique and cannot be copied on the network. Therefore, players can establish sufficient trust relationship as in the real world. This trust relationship is indispensable for the meta universe, and it is also used for mutual information exchange, trading and other activities in the meta universe The foundation of his meta cosmic social activities. Such meta cosmic social activities can even exist completely divorced from the real world. However, the existing online games, such as the glory of the king, do not have such a trust relationship. In order to make up for their shortcomings, some players have to carry out offline activities in the real world.

Of course, if blockchain and metauniverse are only used in games, they can only be the playthings of online game teenagers who are addicted to games. The ultimate goal of the emergence of blockchain metauniverse is to create a decentralized Internet. In this way, everyone's private information will be completely controlled by himself. Instead of handing over their private information to Facebook In the hands of network giants like Amazon, such an Internet structure is naturally a new Internet structure. It is fully qualified to compare it with Web2.0 technologies such as blog and twitter. Therefore, it is not too much to call it Web3.0.
