（1）Web3
The Internet originated in the United States in 1969 and was introduced to China in 1990.
But the Internet was already popular in American universities and scientific research institutions in the 1970s. The main popular Internet application is FTP.
In the 1980s, the Internet expanded from university-scientific research institutions to high-tech commercial companies. After all, these university students have graduated, so this habit has also been brought to the business world. In the high-tech business world, the main popular Internet application is: SMTP email.
The Internet spread from the business world to the masses in the 1990s. Especially in 1990, researchers at CERN invented the Web to disseminate and exchange knowledge, and then in 1993, students at the University of Illinois in the United States invented a Web display tool: the Web browser, and the Internet finally exploded among the public. So in 1995, the information website Yahoo was established, and later in 1998, the information crawling and search company Google was established. Moreover, in 1995, the online shopping website Amazon was established, and later in 1998, the online payment tool PayPal was also established.
As the speed of the Internet becomes faster and the cost becomes lower and lower, people gradually upgrade from Modem dial-up to ADSL fixed broadband Internet access, and more instant interactive applications are also produced. For example, text IM or even show social networks, such as Internet games that require more timely click feedback, such as live video later.
In the past, we had a value-added payment function for playing IM, and we also had value-added payment equipment for playing online games. Our usual way of playing is: exchange real money in the real world for Q coins in the digital world. Spend money on these value-added premium virtual features and virtual equipment.
As for what is called Web1.0, Web2.0, Web3.0, I don't know. Since I went online in 1997, I have been using group chats in chat rooms, BBS group chats/Douban groups/Baidu Q&A Zhihu group interactions, QQ groups/WeChat group chats, Weibo group chats, blogs/WeChat public accounts Comment Reply Interactive Communication.... I have been interacting with online social networks for more than 20 years, and I can't tell which applications belong to Web1.0, Web2.0, and Web3.0.
I am also very much looking forward to the real-time interaction in the VR full reality instead of the real-time interaction in the live video broadcast. I remember that in 1999, Shen Xiangyang's team at Microsoft Asia Research Institute was studying 3D Web page roaming in PC computers. Now that there are VR devices with a more realistic experience, it is possible to realize real 3D roaming instead of 3D Web page roaming.
(2) Ex-universe
Metaverse, wearing VR glasses, you can experience in the digital world as realistic as the real world. In the VR digital world, real-time rendering with a full-real rendering engine, real-time beautification with AI visual and voice technology, and barrier-free communication with people all over the world with AI machine instant translation technology require high-performance smart OS and processing chips.
So we are all looking forward to Apple, which is good at: chips, smart OS, and VR equipment, to launch VR equipment.
In the world of VR All-True Metaverse, my personal opinion: the first killer app is a game.
In the Web Internet world, playing games requires exchanging real money in the real world for Q coins in the digital world. Is this also the case in the world of the VR Quanzhen Metaverse? I don't think so.
(3) Blockchain
Blockchain is blockchain technology. Digital currency is an application based on blockchain technology.
When I first studied blockchain technology and applications in 2018, I said a word: All information (data) can be capitalized. Moreover, this asset can be owned by individuals, rather than belonging to application vendors.
So in 2018, I also had such a brainstorming retreat: all behaviors and information were capitalized, so that digital currency was created from scratch.
Using such digital currency to play VR full-real games is consuming digital currency.
In this way, the entire production-consumption loop is closed in the Metaverse. Everything in the metaverse is self-consistent, and there is no need to bridge with the real world.
In this way, real currency and digital currency do not need to be bridged. Give to God what is God's, and to Caesar what is Caesar's.
