Web 3.0 is hot, but how did it come about?

Web 3.0 is very popular recently, but after reading a lot of opinions, I still don’t understand how 1.0, 2.0, and 3.0 are connected in series, and how did it develop from 1.0 to 3.0? What are the most fundamental changes at the bottom? Are there any rules to follow?

In order to understand these problems, I started to do my own work – the idea is very simple, look at what content is on the Internet, and how this content has changed at different stages.

The shape of the Internet

For the convenience of analysis, I divide the Internet into three layers according to “content, software, and hardware”. From top to bottom, they are the information layer, the connection layer and the network layer.

Web 3.0 is hot, but how did it come about?

The information layer is at the top, which is all digital content, including basic information consulting services, such as blogs and news, as well as generalized interconnected services, such as our most common e-commerce, group purchases, shared bicycles, social networking, Online medical treatment, live broadcast, etc.

The connection layer is in the middle, and its role is to carry information on the physical network and transmit it between different people or things. This layer is currently just a protocol layer. Corresponding to the OSI reference model, the parts above the network layer, including TCP/IP related protocols, and some application layer protocols such as HTTP.

The network layer is at the bottom, including routers, switches, optical fibers, wireless and other network infrastructure. This part is provided by telecom operators. The early Internet was mainly based on fixed networks. With the deployment of 4G and 5G networks, the Internet has gradually become Mobile network transfer.

In fact, when discussing the Internet, we tend to talk more about information and connections, and the physical network layer is attributed to communication, because the physical network is generally provided by traditional telecom network providers, and this part is related to Internet applications. Not directly related by itself.

So, in the different stages between Web 1.0 and 3.0, what has changed in these three layers?

Web 1.0

At this stage, there is still very little content at the information level, mainly news and information. Of course, games and social software also appeared in the later stage. At this stage, the most important tool for users to use the Internet is the browser, to browse some news, BBS and the like. There are also some current large portal sites, such as Sohu, Sina, Yahoo, etc., which require professionals from service providers to provide relatively professional content.

At the connection level, at this stage, the network protocols we have seen have basically been produced. For example, TCP/IP is used for the establishment of network transport layer connections and data transmission, HTTP defines the transmission method of Web content, and the protocol itself supports a variety of information transmission. However, when providing Web services, the “connection” is more of a “one-way” information transfer , which is the main feature of this stage. Therefore, the information is transmitted from the service provider to the user, and the user is basically “browsing” the information.

At the network layer, routers, switches, and optical fibers are already available. The Internet is still carried on the fixed network. Many people may still have the impression of dial-up Internet access through telephone lines. At this stage, wireless is rarely used. GPRS is a way to surf the Internet through mobile phones. , but very expensive, so it is difficult to popularize.

Web 2.0

At the information level, the types and contents of information have been greatly enriched, which is what we see on the Internet today. Food, clothing, housing, and transportation have basically been digitalized. The 1.0 era is to read the news and check the information, and the 2.0 has more entertainment and business colors. This stage has two notable features, one is user participation in content creation, and the other is more emphasis on interaction. The interaction here is not only the interaction between people and servers, but also the interaction between terminal devices and servers, such as sharing bicycles, which depends on the interaction between IoT devices and servers, and live broadcasts, which depend on the interaction between cameras and servers.

At the connection level, there is basically no change in the connection protocol, but the information transfer has become “two-way” , which is what everyone calls ” interaction “, which realizes the interaction between users and services. Users not only “browse information”, but also provide information. But I think “two-way” transmission of information is more accurate. The type of information that users provide to services is not limited to content creation, such as control information of the Internet of Things (bike sharing), order information (e-commerce), etc. are all transmitted from the user side. of. This is the result of two-way transmission. The two-way transmission of information enables the Internet to provide more complex services , both in terms of form and content, such as live broadcasts, which have relatively long and complex interactive processes.

At the network level, a relatively big change is that wireless networks are used for data transmission. The popularity of 4G networks has greatly reduced the cost of users surfing the Internet through mobile phones, and the speed of Internet access has also reached a new level. This is the emergence of mobile Internet. The root cause, of course, the mobile Internet is just a form of network, not a sign of the generational differentiation of the Internet that we want to explain.

What is the logic for the 1.0 to 2.0 change?

The change at the information level is not the reason for the evolution from 1.0 to 2.0, but only the result. What caused such a big change in information is the reason for the development of 2.0.

The “two-way” transmission of the connection layer is the root cause of the change. The two-way transmission of information promotes the continuous enrichment of information content.

After the one-way flow of information, there will naturally be a demand for how the information flows in both directions, that is, interaction. But what is the value of interaction, no one can say clearly in the early days, the earliest Web 2.0 application should be blog, time has proved that this product has not achieved commercial success.

But over time, more and more applications have appeared, and the Internet services we see now are basically 2.0 types, such as e-commerce, sharing economy, and social networking. What we see are business models that require two-way flow of information to be realized, but people did not expect it in Web 2.0, and they were constantly explored in the later stage.

In the early days of the Web 2.0 era, it was more about the informatization of ToC. In fact, the informatization of enterprises is also being carried out simultaneously, but it is not as easy to perceive as ToC, but ToB still has a relatively large space, so everyone is starting to enter the Internet. In the second half, the Industrial Internet.

Therefore, a criterion for judging whether this stage has reached a bottleneck should be, based on the current information transmission method, whether there is still room for expansion at the information level.

The 2.0 era has more room for development than the 1.0 era, and the commercial success is also huge, but the difference between these two stages is only “two-way transmission of information” , which does not seem to be a tall thing. This is also a point I want to express, a small change in the underlying logic can lead to a great change in the upper-layer application. Just like a big tree, if the roots of the tree shake a little, the leaves on the top of the tree will be like a storm.

We can still look at the 3.0 era logically based on this, and what will happen to the underlying logic in the 3.0 era, of course, this change may seem inconspicuous.

Web 3.0

According to the above logic, 3.0 should make some changes at the connection level, and then promote earth-shaking changes at the information level. That is to push digitization to another level.

In the 2.0 era, two-way transmission was realized, but it was basically “two-party interaction” , so what about “multi-party interaction” ? What kind of chemical reaction will occur when multiple parties interact. Will “multi-party interaction” become the underlying logic change in the 3.0 era?

Why is multi-party interaction a direction of change? In our current social software, do you feel that group chats are becoming more and more common, and single chats are gradually decreasing? Are there more and more “circles”, “communities”, and “private domains” on the two-dimensional network?

According to this logic, Web 3.0 can make the Internet form a true “mesh network” at the connection level . Information can be transmitted in a mesh, which is different from the one-to-one and one-to-many interaction mode in the 2.0 era . Web 3.0 has become a many-to-many interaction. The group chat of social network may be a prototype. This many-to-many interaction model is not only valuable in the social field, but may be a basic form in the entire digital society. This basic form is determined by the real society, because in real economic activities, it is many-to-many. It’s just that the current Internet is not fully realized.

Can this change push the upper information layer to change?

The blockchain is a multi-party interactive network. In the early days of the blockchain, some people proposed the Internet of Value. In the Web 2.0 era, “value” did not enter the information level well. Because of the original way of information transmission between two parties, there is no way to solve the ownership of value, and there is no way to ensure the security of value. The emergence of a multi-party interactive network such as blockchain allows “value” to be informatized and transmitted in the network. .

Another more important thing is the circulation of data elements, or cross-organizational data sharing. The simple data sharing between two parties is obviously not called the circulation of data elements. Only when more parties participate in data sharing, the value of data can be realized. . This is also the point of view I expressed in the last time I shared “How to achieve data cross-agency compliance and security sharing through blockchain + privacy computing”.

Whether it is the Internet of Value or the data element circulation network constructed by blockchain + privacy computing, it may only be one of the incremental changes in the information level in the 3.0 era. The Metaverse and the Industrial Internet will also provide rich information content for the 3.0 era, and They also all need “multi-party interaction”, not just two parties.


It is indeed difficult to generalize how the Internet has developed from generation to generation, but the change in the form of connection has indeed changed the Internet, and perhaps it will evolve in this direction in the future, so “multi-party interaction” is the fundamental driving force for the development of Web 3.0. How to realize this “multi-party interaction” network? Blockchain may be an option.
