Thank you for your invitation.
Now let's look at a simple explanation!
When you watch at home《 Chang'an Twelve Hours 》At that time, a cloud miner next door to Lao Wang's house was continuously transmitting the video files of the next episode for you; You paid a membership fee of 15 yuan to the video website to watch the play. Lao Wang's mining machine earned 20 cents a day by passing documents to people nearby.
You are an ordinary Internet user, and Lao Wang is a Web 3.0 participant.
Recently, you may have heard and seen a lot of content related to Web 3.0. Are you like Block rhythm The members of the BlockBeats team are also thinking: Web 3.0 and Blockchain What does it matter?
In the traditional sense, Web3.0 is a new stage of Internet development. It is based on the current Internet (or you can call it Web 2.0), and the changes brought by Web 3.0 have brought the Internet to a new level of development. Computer scientists and Internet experts believe that these changes will make the Internet more intelligent and our life will become easier.
The practitioners in the digital cryptocurrency industry have higher expectations for Web 3.0. They are now looking forward to breaking the monopoly of traditional Internet giants and creating a new free world. The Web 3 Summit, which opened in Berlin, Germany, on August 19, will also fully discuss the topic of Web 3. Perhaps we can learn more about Web 3 in this event.
So, in order to better understand the changes of these paradigm shifts, let's first look at the development stage of the Internet.
Web 1.0 ->Web 2.0 ->Web 3.0: Evolving
The trend we are about to witness is that the Internet will develop with the needs and use of users, and ultimately belong to users.
Web 1.0 - website feeding information to users
According to the content of BlockGeek website, as early as the 1990s when the Internet was just beginning to become popular, the interaction between users and the network was at a very early stage, that is, users can only passively browse text, pictures and simple video content, what the website provides, and what users see. There is almost no interaction.
As for the post 90s and post 90s generation, there was an Internet (early) version before the popularity of social media and video streaming media! In the late 1990s, before the development of Google and Baidu, the Internet was once dominated by AltaVista and Netscape. At that time, the Internet only existed to promote their physical companies. These sites are "read-only", meaning that you can only search and read information.
(# Block Rhythm Blockbeats Note: AltaVista, one of the most famous search engine companies in the world, was founded in 1995. It was acquired by Yahoo in 2003, and Yahoo announced to close the search engine AltaVista service in 2013. Netscape, Netscape Communications, was once an American computer service company, and was famous for its Netscape Navigator, a web browser of the same name. In November 1998, Netscape Acquired by AOL.)
In fact, the e-commerce websites of that era, like the hypermarket promotion brochures, only show you the content, and you can't place an order on the website.
This is Web 1.0, slow Web 1.0, and fully controlled Web 1.0.
Web 2.0 - Internet starts to interact with people
The next generation Internet is called "Web 2.0" or "read-write" network. Now, users are not just visitors, they can also create their own content and upload it to the website. Take the famous video blogger "Office Ono" as an example. It only took her two years to change from an unknown video writer to a video major with a monthly income of tens of millions.
From about 2003, Dale Dougherty, the vice president of O'Reilly Media, first proposed the word "Web2.0", and then the wave of "Web2.0" swept the world. In just ten years, "Web 2.0" has completely redefined marketing and business operations.
Influential online celebrities only need to send a video to make a restaurant full of queues, or use a sentence to make an online store full of negative reviews. The influence of Internet people on the Internet is growing day by day, and the past era of websites feeding information to users has passed.
The main goal of Web 2.0 is to make the Internet more democratic and accessible to users wherever possible.
Web 3.0 - More Human Internet
In the eyes of traditional Internet people, Web3 may be like this.
Every time you buy something on JD, the algorithm of the website will recommend it by checking other products purchased by users who have bought a product like you or according to your previous browsing records and purchase records. What happened in the process? The website is learning your potential preferences from other users, and then recommending you what you might like. In essence, the website itself is learning, thus becoming more intelligent.
They believe that " Web1.0 It is mainly driven by the content generated by enterprises or institutions to attract their customers. Web 2.0 enables the Internet to further develop by users to upload and share their content on the website. Web 3.0 via Online applications And websites receive information from the Internet and provide users with new information or data. "
For example, on the semantic network, what is the difference between "I love Bitcoin" and "I<3 Bitcoin"? The syntax of two sentences is different, but the semantics are the same. In our example, the semantic processing of the meaning or emotion conveyed by the data makes these two sentences express the same emotion. Semantic Web And artificial intelligence are the two cornerstones of Web3.0. With semantic metadata, Web3.0 will enhance the connection between data. As a result, the user experience will evolve to another level of connectivity, leveraging all available information.
Another example is AI, which will filter through websites and provide users with the best data possible. In the current Web 2.0, we have begun to adopt user opinions to help us understand the quality of specific products or assets. A website like Rotten Tomatoes where users can vote and score movies. Films with higher scores are generally considered as "good films". Such a list can help us obtain "good data" without having to obtain "bad data".
Another example is advanced 3D images. Imagine that in online games like Second Life or World of Warcraft, users are far more interested in their online characters than they are in their real selves. Philip Rosedale, the founder of the game Second Life, believes that virtual identities will be as popular as email addresses and mobile phones. This view seems far fetched, but don't forget that in 1997, 20 years ago, only a few people had their own e-mail addresses. In the future, more and more people will have 3D identities.
Finally, the Internet will be everywhere. We have already obtained this function in Web 2.0. For social media websites like Instagram, users can take images on their cameras, upload and distribute them online, which becomes their intellectual property rights. Therefore, images become ubiquitous. The development of mobile devices and Internet access will enable you to experience Web 3.0 anytime, anywhere. The Internet will no longer exist only on the desktop like Web 1.0, nor on smart phones like Web 2.0. It will be ubiquitous. Web 3.0 can also be called the ubiquitous network, because most things around you are connected online, that is, the Internet of Things.

The real Web 3.0 -- the Internet controlled by people
From the above description, Web 3.0 is a more suitable Internet for human use, and its service for human is more excellent and natural. But what does that mean? This means that users need to provide their information to AI and service providers in large quantities for free, so that they can train AI models to provide better recommendations and semantic associations. The ubiquitous Web 3.0 experience will also lead to the disappearance of Internet users' privacy. Businesses know who you are and what you like to eat, but you know little about businesses.
Privacy, data, rights, censorship, identity... these are all topics of concern for Blockchain Web 3.0.
In the digital cryptocurrency industry at the forefront of Internet technology, insiders have different views on Web 3.0. They believe that the Internet has long been riddled with holes, and the four attributes mentioned above are only the inevitable stages of the development of the Internet, but they are not enough to constitute Web 3.0.
real Web 3.0 Several characteristics of
If Ono in the office gets 100% of the advertising share instead of 30% or 40% of the platform, she will get more income. However, in the current Internet stage, this goal is almost impossible to achieve, because the traditional Internet is centrally operated and monopolized by Internet giants, and operators need to pay for various costs.
Web 3.0 needs a new paradigm to overturn the monopoly of today's Internet giants and protect the interests of every Internet user. Benefiting from the decentralized storage, tamper proof, information encryption and other characteristics of blockchain technology, combined with the recent research summary of BlockBeats, we can roughly label Web 3.0 as follows:
1. Unification Identity authentication system
2. Data confirmation and authorization
3. Privacy protection and anti censorship
4. Decentralized operation
For many problems on the Internet at present, such as the need to repeatedly register accounts, the abuse of user privacy data by service providers, the use of user data by network companies, and the inability to continue network services, the four tags mentioned above can be used individually or in combination to become Web 3.0 solutions. The corresponding attribute, Block Beats, will be explained and discussed in detail in the following articles.
BlockBeats will also give readers a good view of Web 3.0 and a bad view of Web 3.0, so that readers can fully understand Web 3.0.
Web 3.0 will bring a transparent and credible Internet economic model
Because users have been using Internet content for free for decades, people are interested in《 User Agreement 》The way of giving free access to websites and service providers in the form of Privacy Agreement is not repugnant, and even takes it for granted. However, we have neglected that the money earned by enterprises using users' data will not be returned to users. Users have no right to obtain the remaining profits after the revenue covers the operating costs. Many people take this for granted, but it is unfair.
Whether it is Web 1.0 or Web 2.0, because the centralization of operation services always brings transparency and trust problems more or less. This problem can be solved through the application of blockchain technology of data rights and interests authentication, data right confirmation and authorization. The data generated by the user in the Web 3 world belongs to the user, and the user has no right to use it without the user's authorization and confirmation. At the same time, users may also get a share of the benefits generated by the use of data through the token economy of the digital cryptocurrency industry.
The emergence of token economy and digital assets has also given users the opportunity to participate in the operation of Web 3.0 development companies. They can participate in voting and dividends, and achieve benign interaction between developers and users. Users are both users and maintainers. For example, the Brave browser recommended by BlockBeats before, when users surf the Internet in the browser, the browser will recommend advertisements to readers, and at the same time, it will return some income to readers. It not only consumes users' data, but also creates income for users. In the future, more such products will appear, allowing users to participate in the operation of the company. Fred Wilson, partner of AVC Capital, believes that this behavior can be understood as Open Data, which is an important link in the development of Web 3.0.
Lao Wang mentioned at the beginning of the article, because he participated in the mining of a project, his mining machine was used as the CDN node of a video website to deliver video files to nearby video users, calculate his workload according to the uploaded traffic, and then share the money from Youku, iQiyi or Tencent Video. Lao Wang is a very standard Web 3.0 participant. He can enjoy the convenience of the Internet and make money for his contribution.
Web 3.0 will let users use it with confidence
In the field of traditional Internet, the control right of users over their own data is actually very low.
For example, your blog posts may be deleted because of a "stop service announcement" on Sina blog. Even the copyrighted music you buy on Netease Cloud Music will be deleted from the App because of the expiration of Netease Cloud's copyright, and will never be heard again. Your favorite game may also be "disconnected from the server" because the developer can't make money, which makes your equipment disappear after several months of playing.
In the field of traditional Internet, all this has already happened, and more will happen. In the era of Web 3.0, this problem will be solved through decentralization.
Like Ethereum 2.0 and Dfinity, the blockchain of global computers will provide developers with basic computing services, without the need to rent servers, and user data can also be accessed through IPFS, Sia, OrbitDB (using IPFS Decentralized database ）No one can control your data any more with decentralized storage technology. As long as you are willing to pay for the blockchain smart contract that the game runs, you can still play even if you are the only one left in the game.
Changes to products and games must also be voted by the community, and developers no longer have the right to dictatorship. Vitalik Buterin, the founder of Ethereum, was furious because the online game World of Warcraft randomly modified character skills. The emergence of Web 3.0 will limit this situation.
Web 3.0 is ruthless but can be extraordinarily fair
Web 3.0 is actually cold. It doesn't have feelings. Only in this way can it serve all people faithfully.
The application of Web 3 in the financial field will also exceed our imagination of the current financial industry, and has already been implemented. Take the MakerDAO decentralized lending platform as an example, on which users can obtain a stable currency DAI anchored in dollars by over mortgaging digital assets.
Blockchain and smart contract have no feelings. They treat everyone equally. They only recognize the tamper proof records and real digital assets recorded on the chain.
When you enter the bank, the bank should check your qualification, check your source of funds, and then lend you your collateral after a long review; Defi in Web 3.0（ Decentralized finance ）There is no such centralized organization to compare and review. Whether you are a homeless man driven out of your home or a Wall Street tycoon in a suit, the MakerDAO smart contract deployed on the Ethereum blockchain will unconditionally receive your digital assets and lend you stable currency.
In the real world, you may be able to gain the trust of others through rhetoric, but Web 3.0 does not listen to this. It is a machine without emotion. It can neither cheat nor be cheated. Similarly, it can almost "trust" when doing business on the blockchain. This behavior is also called Fred Wilson Open finance （open finance）。
Web 3.0 is inefficient and difficult to popularize
However, it is undeniable that there is a major problem in the new Web 3.0 world: inefficiency. This is directly related to the decentralized operation of Web 3.0 recognized by blockchain practitioners. Compared with centralized Web 2.0 and traditional Web 3.0, the efficiency of decentralization is much lower.
First, the speed of task processing in the decentralized network is low. BlockBeats believes that any practitioner in the blockchain industry will recognize this, and even those so-called Web level blockchain projects cannot hide the fact of low efficiency; Then use Decentralized network The implicit cost that needs to be paid will confuse users who enter Web 3.0 with the concept of "service charge". The original Internet has no service charge at all.
The content of popular science for users in Web 3.0 is far more than that of blockchain, Bitcoin and cryptocurrency. Of course, developers can also design applications that are no different from traditional apps through a variety of designs, making users not feel these complex operating mechanism The exists of. However, such development tools are just starting.
The popularization of Web 3.0 may be very difficult. Whether it is for developers, users or enterprises, it will be unusually difficult. Especially in the era when countries and regions around the world are trying to strengthen Internet regulation, Web 3.0 is confronting politicians.
Plus the token economy and human selfishness, speculation is far more profitable than doing projects. In order to gain public trust, the development team even needs to show up regularly to prove that they are still working. How to run the blockchain like the traditional Internet while maintaining the characteristics of the blockchain is a problem that blockchain developers are still struggling with and exploring.
Whether Web 3.0 is worth existence
This is the voice of the overwhelming majority against the concept of Web 3.0. They believe that today's Internet has developed to an almost perfect stage. Users have become accustomed to selling data and subscription system, and are unwilling to enter the Web 3.0 world after getting used to it.
In this regard, they think that the concept of Web 3.0 is unnecessary, because it has entered the stage of Web 3.0. From the perspective of user acceptance, Web 3.0 seems to be unnecessary, because today's Internet can meet the needs of all people.
However, from the perspective of decentralization and personal rights protection, Web 3.0 has its value. But its value needs to be tested by the market. This may take a long time. It is necessary for Web 3.0 to exist from the perspective of digital cryptocurrency market, but whether it is worth our time to wait is another matter.
To be sure, whether developers, blockchain operators or users, Web 3.0 is no longer just waiting to enjoy like Web 2.0. Only active participation can create a new Internet world that truly enjoys rights and is worth traveling in.
