foreword
Hello everyone, I am Qingfeng. The Internet connects people. In the past 30 years, Internet technology has continued to evolve, evolve, and develop in depth. Politics, economy, social interaction, life, and work are almost inseparable from the Internet. We have experienced WEB1.0, WEB2.0, and now WEB3.0. We all know that now we have developed to the 5G network, and WEB has to move forward. WEB3.0 can be understood as an upgraded version of WEB2.0. In the development process of the Internet, it can be divided into three eras, and we will introduce them respectively below.
1. WEB1.0
net, etc.). At that time, portal websites were popular on the Internet, such as Yahoo and America Online (AOL) abroad, and the four major domestic portals such as China.com, Sina, Sohu, and NetEase. Of course, some people joked that there is only one big portal in China, that is, Hao123, because this website navigation station "occupies" the user's browser. As long as the user opens the browser, the Hao123 website will be opened by default, making it a real portal. Familiar with the early days Everyone on the Internet knows that Hao123 was later sold to Baidu, and its founder Li Xingping and 265 (sold to Google) founder Cai Wensheng also developed a portal - 4399 for children to play games. Of course, there are still some portals such as Tencent, FM365, Yitang, 21CN, etc., most of which have disappeared. These portals mainly release information, mainly news, and the users who surf the Internet mainly watch it. This may be the meaning of the so-called "readable" Internet. Because of the emergence of the Internet, business "prosperity" has been brought about. A large number of corporate domain names can be Internet companies by adding an "e" before them. With a "DOT-COM" domain name, you can write a business plan and then go to NASDAQ in the United States. listed. The initial browser company Netscape and others were all favorites of the stock market. With the burst of the Internet bubble in April 2000, a large number of Internet companies stagnated or closed down, and the market value of Nasdaq also evaporated sharply, including NetEase, which almost kicked out Nas Dark. Of course, it would not be objective to say that the Internet at that time was only "readable". In that era, there were actually many ways and platforms for "interaction", such as email services, message board services, chat rooms, forums, blogs, etc., well-known There are also many platforms, such as 163, 263, Bihai Yinsha, Tianya, Blog China, Lianzhong (card and board games), 5460, Renren, Maopu, etc. There are also corresponding protocols such as: SMTP, FTP, etc., but the overall interaction Sex is weaker, and a large number of platform interactions stay on services such as comments. However, there are three relatively large services that became popular at this stage, one is e-commerce services, the other is search engines, and the other is instant messaging. Representatives of typical foreign e-commerce such as Amazon, eBay, Global Sources, etc., domestic representatives are Alibaba and HC, and of course the alternative Sinochem.com. The SARS outbreak in 2003 led to the rapid development of online shopping. The typical 8848, Joyo, Dangdang, Sohu Mall, the real last laugh is Taobao, Joyo almost died after being acquired by Amazon, Dangdang is still there, although it has been on the market for a while , also acquired the domestic maternal and child platform Red Baby, but it is indeed not as good as before. In terms of search engines, Yahoo is a pioneer Zu, Sohu imitated the most in China, but after Google launched a search service based on "keywords", Yahoo's directory-based search immediately declined, and Sohu search was also shut down. Of course, Sogou search was launched later, and then It was Baidu, Yisou and other searches that followed, and eventually Baidu became the number one player in the search field in China. In terms of instant messaging, ICQ and MSN are well-known in the world. Ma Huateng launched OICQ based on ICQ, and later changed its name to QQ, which is now Penguin Dachang. This was the BAT at that time, and some people said that Jingdong should be added, which is BATJ. In terms of organizational form, this era is not much different from traditional enterprises, but it has created a large number of new jobs for Internet companies. Loyal fans of the Internet put forward the spirit of the Internet at that time: openness, sharing, and borderless, but it was like that at the time.
Two, WEB2.0
The Web 2.0 era is the Internet era we are in now. With the continuous development of technology and applications, the Internet is showing prosperity, especially the domestic Internet, which can be said to be the world's top in the field of application, followed by the emergence of a large number of giants (big factories), in the name of building platforms Form a large number of business empires. The remarkable feature of this era is that one family dominates and the strong will always be strong. There is a law of duality in the traditional marketing field. It is said that in a market where competition tends to be saturated, there will generally be two big brands monopolizing the market, such as Coca-Cola and Pepsi, Crest and Colgate, McDonald’s and KFC, etc., but in the Internet field , will always be the dominant player, such as the existence of Taobao, so that Yihaodian, Vipshop, Youah, Paipai, and Suning Tesco have hardly gained much market share, Alibaba almost monopolizes the B2B market, and Tencent monopolizes the instant messaging market. Meituan monopolizes the food delivery market, Baidu monopolizes the search engine market, and so on. The distinctive feature of Web2.0 is "interaction". Users are not only the acquirers of content but also the creators of content, which is commonly known as UGC (User Created Content). Typical applications such as Twitter, Youtube, Uber, Weibo . user. Due to the emergence of a large number of platforms and applications, users need to register a large number of platforms, APPs, and small programs. Account passwords are pushed a lot, and mobile phones have to collect verification codes, advertisements, etc. every day. This is the so-called "centralization". The created content and user information are so-called big data for various profits, and basically have nothing to do with users. On the contrary, users are harassed by big data, and there are even cases where big data is "familiar". The emergence of the concept of "Internet +" has led a large number of traditional enterprises to explore the road to the Internet. From e-commerce, Internet promotion, content marketing, live broadcast delivery, O2O to internal information transformation of enterprises, etc., they have also invested in the Internet army. However, the early Fortunately, in the later period, due to the disappearance of Internet dividends, a large number of companies invested a lot of energy, financial resources, and manpower on the Internet, but the gains were quite small, but they had to participate, which was very embarrassing. In terms of organizational form, the concept of "flatness" was proposed in this era. Because the Internet requires timely response and quick decision-making, this concept of organizational form was introduced. Xiaomi's Internet thinking of "focus, extreme, word-of-mouth, and fast" is not accurate enough, but it is a representative of this era. The spirit of the Internet proposed by the first generation of Internet people, in Web2.
3. WEB3.0
As the contradictions continue to emerge, WEB3.0, also known as WEB3, a network era that supports openness, no trust, and no permissions will follow. WEB3 understands and can meet user needs, understand user habits, automatically filter resources, intelligently match, and give user answers. WEB3.0 is a process from user to network and then to user. Artificial intelligence is the best example. The Web3.0 era, the coming era, is also the most hyped concept at the moment. As a large number of investment institutions and traditional Internet companies have entered the game, they have invested heavily, earning enough attention from enterprises and users. There are also different opinions on the concept of Web3.0. A typical feature of Web 3.0 is ownership. Because it is a decentralized model, the previous generation of big factories will be "revolutionized" because they are typical representatives of the centralized model, and they are extremely centralized, centered, and intermediary. In the ideal Web3.0 era, after users create content, they don’t become the content and data of big companies, but own their own ownership. Whoever wants to use it must be authorized or paid for it. That is to say, users are the creators of content. The owner is also the owner of the content. Secondly, in the entire Web3.0 era, the user's identity is unique and unified. Unlike the previous era, each platform and application must register an account, and the accounts are not related. It is no longer needed in the Web3.0 era. A set of accounts can be used all over the world, and the account information is encrypted and kept in your own hands, which is extremely safe. At the same time, based on the application of distributed storage, all kinds of data are also safe and will not be used by large manufacturers at will. What's more, the Internet in the Web3.0 era is a trusted Internet. Based on the trust building of blockchain technology, trust does not need to be confirmed by intermediaries or centralized organizations, and anyone can do it. Monopoly will also cease to exist in this era. With the application of blockchain, distributed storage technology and ideas, monopoly (centralized) organizations will be removed step by step, and finally achieve P2P (end-to-end), that is Fair and open. The "result" is not controlled by the big factory, but is determined by the smart contract opened by the air, and the causal cycle. In terms of organizational form, the new decentralized autonomous organization (DAO) will be greatly applied, and co-creation, co-construction, sharing, and co-governance will form the standard and mainstream. The Internet spirit proposed by the first generation of Internet people may be realized in this era, based on technology, but also based on ideological progress, perhaps based on helplessness.
