What is web3.0

What is WEB3.0? Industry expert annotation: namely "web3.0= Internet + Communication Service (Internet+instant Communications)", namely through the Internet and communication fusion, users can use all intelligent terminals (fixed telephone, mobile phone, PC, IPTV, Other intelligent terminals easily enjoy the instant interactive information services that can be seen, heard, and used well, and it must have features such as immediacy, integration, interactivity, personalization and autonomy. The core difference between the services provided by WEB3.0 technology and the current Internet service is that the WEB3.0 is based on personalized, subscribe-and-push service, while the current Internet service is a real-time service around the search engine.

Look at the picture:

What is 2.0

Definition: The so-called 2.0 is the Internet application concept and architectural upgrade, rather than a simple technical innovation or some kind of application

Ajax, blogs, rss, wikis, these are web2.0? Ajax is just a kind of javascript application that has been in existence for a long time, blog is just an improvement of personal homepage, RSS is just a format in XML.

So the key is no longer the technology, but the idea. On the idea, Ajax is highly recommended for asynchronous Web applications; Blogs promote a people-centric content management; RSS brings together disparate personal content effectively.

web2.0 during the application, although there is a certain amount of technical content in the inside, but that is not the main factor, you can not explain the technical web2.0,blog far less than the BBS system technology mature and complex, but the idea is more avantgarde.

I used to hate the name of web2.0, mainly because some people have been fooled by the blind. But it must be admitted that web2.0 was indeed a very successful name. So today, by this name, it's called web3.0.

2 web3.0

2.1 web2.0 just start and transition

Web2.0 Although the concept of a certain upgrade, but still far from enough, we can still see a lot of problems, I only said three: Blog publishing system, comment system and plug-in applications

2.1.1 Publishing System

Content management is the most basic function of blog, now the system of blogging is nothing more than the realization of What you are What you (WYSIWYG) visual editing, realize the classification, complex point of the implementation of tags. The ability to index content is very poor without exception (bloggers may be better, specifically did not study), version control does not seem to have any blog, now it seems that these features are slightly more complex, but when a blog backlog of 1000 articles, indexing and modification will become very difficult. Like my blog, want to find a history article, I use Google to search, want to change what text, I would rather write a new one, want to rearrange the whole blog? Then I must be crazy--

So, the future blog (in fact, also does not matter blog, should be a personal network center, I will talk about) content management will join now wiki inside the version control function, integrated powerful full-text indexing function.

I have not updated the blog for a long time, most of the reason is the background is too difficult to use, today installed live writer only power to write an article up. I'd rather spend a few more minutes downloading and installing a client, and save a lot of time while enjoying a more powerful editing function, before the speed of the Internet and the browser are not fast enough.

2.1.2 Review System

Above I said that the technical maturity of the blog is far below the BBS, the comment system is one of them, throughout all the blog system and BSP, I have not seen which blog system comment function can be compared with discuz. Blog does not require complex comments? Then you are wrong, to see Lao Xu's blog, the article is not a few hundred comments? Do you think Sina's comment system is enough? It has at least pagination, more than I use MT, but still can not achieve rich content editing and indexing.

Said the comment system has to say is trackback,trackback as a blog Content association comment function, originally is to want to fill cross station content correlation function flaw, but realizes is too lame too simple, so many people do not know this thing how to use, but is Spammer find a gap to use. Now has become a chicken ribs, many people in the threatened Trackback has died.

In addition to the comments outside the trackback, the message can not be managed and monitored, although some blog system has the function of automatic mail reminders, but this is far from enough.

So the future review system will certainly be strengthened.

2.1.3 Plug-in Application

Blog system is far from the issue of system and comment system, Plug-ins are currently filling the system function of the most effective means, the success of WordPress, on the benefit of the perfect plug-in platform, has been the support of the vast number of developers.

But WP's plugin system flaw is obvious, I did many years of PHP development of the people, use up all feel the head is big, non-technical people needless to say. In addition, WP plug-ins are not able to migrate to other platforms used, especially the Cross-platform platform.

Now there are some foreign platforms, already doing such a standard, through a restful URL can ignore platform limitations, using Plug-ins. For example, Netvibes, Facebook, IGoogle, Live, domestic, Sohu Blog also introduced netvibes UWA framework, try to do open blog widget platform.

This is a bit like the application of RSS, the use of XML standards to promote content dissemination, the Open widget is a widget as a content, through the standard of XML dissemination.

No service provider or platform developer can meet the needs of all users, only the open world is what everyone expects, so the open widget will certainly become a trend.

Well, say so much, can't but want to prove web2.0 just an excessive, then what is web3.0?

2.2 What is web3.0

In fact, many people should have seen that there is no so-called 2.0, 3.0, because you can not accurately define what kind of application he is, and cannot define when it began, when the end, it is only the development of the Internet itself a trend.

The 3.0 I want to say is the framework for the future of Internet applications that I can now imagine.

A, the site information can be directly and other Web site information to interact and sell, through the third party information platform at the same time on a number of web site information integration use;
B, users have their own data on the Internet, and can be used on different websites;
C, completely web-based, using a browser to achieve complex system programs to have the function
It can be said that Web3.0 is a three-wide + three-span (wide-area wide range of broad language across the region across the language Cross-industry)
In reality, every industry is in the continuous subdivision and improvement of the development, such as the construction industry, the financial industry, have been relatively clear division and still refining, which is hundreds of of thousands of years of development in the process of building up. But the internet has only developed in just more than 10 years, for a field that can cover almost all traditional industries, the level of Internet application is far from enough. As is said in software engineering, the standards and specifications are very simple, the development methods and modules are far from enough reuse.

The same is true of the Internet, and the degree of subdivision, completeness and reuse of various applications is far from enough.

So I think, the future development direction of Internet application must be toward more subdivision, more professional, more compatible direction development, content management will have the professional content management provider, comments will have the professional comments service provider; Plug-ins will have a unified standard similar to RSS, And there will be a widget hosting platform and a subscription platform like FeedBurner, Google Reader.

Blog, will evolve into a personal center, the personal center of all the content only a domain name and a page, the rest of the services are provided by professional service providers, users need only to use the widget to add to their own page, you can enjoy a variety of perfect service.

But it will not be a centralized personal homepage like Google IG, Netvibes, because they have no personality and are not flexible enough. It will not be Sohu such a blog platform, because a variety of services are not provided by a company, BSP may return to the most original personal homepage service, provide a level two domain name and a static space.

So one of the main questions: who is providing the account number? OpenID will certainly become the backbone of the web3.0, the various platforms to connect organically, is that wherever you go, all with the same account, the content is related everywhere.

and the ID service itself needs to be linked to credit, this is the virtual and reality must be built between the bridge, the existing community in the credit services are based on a certain technical means to build, are very laborious, and can not be with the real people and credit to establish a complete and effective relationship, it is not difficult to think, directly grasp the most reliable credit is the bank, So in the future to provide OpenID or Internet identity Services will be a bank set up a service, it is likely to become a bank of some kind of business.

In this mode, Internet services have been the same as the traditional service industry, the provision of professional services, fees, the Internet's profit model will also change.
