First we need to understand these points: "Why do we need Web 3.0", "What's the difference", and "What does it bring us" ...... Wikipedia has a very perfunctory definition and no authoritative definition of the Internet, so I'll start by explaining it from my own perspective.

Web 1.0 to 3.0 is building a world

Web 1.0
The dream of virtual worlds has been around since the birth of the Internet, when people discovered that there was a window to a different world beyond the real world. We will use the word "window" repeatedly below, and we compare it to the connection between the Internet world and the reality world.

In Web 1.0, this window was much smaller or completely closed, and we could only access the information that was fed to us through this small window. For example, a company no longer has to struggle with the fact that other cities are unable to notice them, even buying train tickets to go around the world to do exhibitions. Because they could put themselves on the Internet through that window for people around the world to notice them.

Web2.0

Since Youtube, Google, Amazon and other platforms appeared in this window, the Internet began its first peak: Web 2.0, which is the most profoundly experienced by the 80s and 90s of our generation. At this stage, the Internet began to have the attribute of "people" and gradually changed the way of life of humanity. From this time onwards, mankind can feed information to the opposite side through this window, instead of only passively receiving as before.

For example, we can upload our own videos in Youtube, tiktok and other streaming platforms, and other users can access and watch the content we upload through the platform. For example, we can sell goods on e-commerce platforms such as Amazon, and other users can browse and buy our online store through the platform.

Most of this content is still controlled by the enterprises and platforms on the left side of the window, they theoretically will govern and maintain this information with the principle of legal compliance, while their power also includes how your videos, merchants and other information is displayed to others, at the beginning of this point in the processing method is basically very simple, the first basic data is the real number of views of this information, time and other objective data of the sort, followed by Advertising fees, in the case of the law allows who gives more money to put the advertising on top. But today's development on this point of processing increasingly advanced, when you are browsing Facebook or tiktok, you will usually find that these platforms will be very magical to push you like to see the goods and programs, because the other side of the window has gradually been trained to become your attentive secretary, it seems to be a person who knows you very well, always pushing you what you want.

Who is able to train emotionless websites and programs to become a "person"?

Big data, artificial intelligence, robot learning and a series of technical methods are gradually personalizing the Internet. At this time, the "person" opposite the window is constantly accumulating and receiving information about "my" interests, knowledge and experience, turning into a personal one-to-one secretary controlled by the enterprise and the platform, constantly telling the enterprise what they need, so that they can provide better and more accurate services to their clients.

At this time, Web2.0 realized the exploration of the virtual world on the left side of the window on the right side of the human, while the virtual world is instilled to AI through the information brought by humans and continuously trained and learned.

Web 3.0

Strictly speaking, the concept of Web 3.0 is proposed because the next generation of Internet will undergo great changes and progress from the underlying technology to the application layer, which is beyond the scope of the current concept to explain and cover. So at this point we go back to Wikipedia's definition.

Web3.0 is mainly based on the decentralization of blockchain, cryptocurrency and non-homogenized tokens.

This definition is truly simple, because the only definitive concept that can be given is the relevant technical architecture, and the application layer is not yet fully developed, which means based on these technologies, exactly what kind of applications humans can create and what value they bring to social civilization is not yet known.

So……………………are we finished?

Of course not, a new technology is necessarily a pioneering journey, first we have to figure out

"Why do we need Web 3.0?"

"How is it different"

"What does it bring to us"

Figure out these three issues, maybe you will also firmly embark on this journey. Since Web3.0, "window" is no longer a boundary, and human beings will pass through this window to control the other side of the world.

Why do we need Web 3.0?

The development of the Internet can be roughly imagined as a process in which the demands of the human being gradually influence the demands of life. Weekend shopping at the mall. But at the end of Web 2.0, the Internet has infiltrated much of people's lives. How far has it gone? We cite data from the <Digital 2022 Global Overview Report>.

Global Internet Users: By early 2022, global Internet users have climbed to 4.95 billion and Internet usage now represents 62.5% of the world's total population.

At the same time, global Internet users are spending nearly seven hours a day using the Internet on all their devices.

The phenomenon we can see is that there are decreasing number of stores in physical malls, electronic payment has almost replaced banknote circulation, and people cannot live without their cell phones in their daily lives. This shows that the Internet has become an important infrastructure in mankind's life, and therefore the point I want to make is that the degree of health, wealth and developability of the Internet is extremely important. So we need Web 3.0 to be able to do the following things.

1. The Internet should be healthy enough not to cause big losses due to technical failures, and not to make the Internet world unfair due to the collapse of a giant company, where the information and ownership is truly in the hands of each user.
2. The Internet should be rich enough to create more than just a small secretary who knows your interests, but a virtual world space that can further meet the needs of humans for mental, entertainment and life. This concept is already available today, known as " Metaverse ".
3. The Internet has to be open and expandable, and it relies on all users to develop and expand, not just a few companies or operators.

What's different about Web 3.0?

The biggest difference among the many features of Web 3.0 is the decentralization of power, which is what the market has been talking about, "decentralization", and the controversy of decentralization has never ceased because people are still accustomed to the form of social services with authority and trust, for example, people may not know the risk control and assets of banks, and few people read the information reports of banks themselves every year. The reason why people are willing to deposit their money in banks is because they trust the current social system and rules, and they are completely depending on the authorities who make the rules of the game.

It is important to emphasize here that many people reading this may think that Web 3.0 advocates are a group of anarchists, but in fact they are not. We should know that as the rapid development of the network and the information age, evil and violation of the methods and means will be increased, many situations are difficult to restrict under the established rules of the game, or we are unable to guarantee that the individual rule makers will never be corrupt.

What does Web 3.0 bring to us specifically?

First we need to unify one view.

Machines are more reliable than humans when it comes to replaceable or repetitive tasks.

Web 3.0 has the ability to create a world that can operate independently without centralization (people, companies, institutional groups) simply by setting rules, while at the same time constantly motivating people to evolve those rules. If the rules that maintain order in the real world are called laws, then the laws of the Web 3.0 world is an evolving smart contract.

So Web 3.0 can bring us something that is full of imagination, for you can create anything that is already quite mature in the real world, and the chain is filled with new things. For example, decentralized finance (DeFi), digital artwork (NFT), on-chain games (GameFi), etc.

Let's break down the application areas where Web 3.0 has been born so far.

1Space
Space is a container for a world, all the applications and demands exist in the container, so there is a respective territory, we can also imagine it as a country, these countries can be public chains, Layer2, side chains , private chains or alliance chains. Each chain is created for different purposes, with different technologies and different needs, so it is more appropriate to consider them as one country, and these countries are constantly relying on their own advantages to create infrastructure, foundation and application ecology to attract users and developers.

2 Finance
Financial products were arguably the first demand to be born on the blockchain. On January 3, 2009, Satoshi Nakamoto, the founder of Bitcoin, left a classic phrase in the Genesis block that can never be modified: "The Times 03/Jan/2009 Chancellor on brink of second bailout forbanks."

The first representative application on blockchain after this - Bitcoin - ruled the blockchain market for more than 10 years, which is why blockchain has been labeled as financial, but from today's perspective, blockchain applications, although still mostly built on Token economics, are essentially with the emergence of smart contracts and technologies such as NFT There has been a breakthrough in the nature of

Decentralized financial products (DeFi), which started to take off in the years after the birth of ethereum, quickly gained support from users by taking advantage of the blockchain's transparency, traceability and anonymity, and here is a classic example from the web.

When you deposit money in a traditional world bank, you get a deposit slip or a contract. The bank then lends your money, and possibly along with other users' money, to those borrowers in the form of a loan, or takes that money and reinvests it. The process is like putting your $1 into an opaque cup and then putting the cup you are in into one of countless other such opaque cups. Eventually you may get your $1 back, but you never know how your $1 is exchanged and circulated in this group of cups. DeFi solves the most straightforward problem by replacing all these cups with transparent cups. 1 dollar is still 1 dollar, the bank's business is still the same, but you can clearly see where 1 dollar comes from and where it goes.

3 Material
If Token opens the big economic era of blockchain, then NFT signifies the coming era of blockchain's maker.

The full name of NFT is called non-fungible token, which simply represents the uniqueness of a single substance. For example, when you hold ETH, there is no difference between your 1 ETH and other people's 1 ETH, which is homogenized. For example, if I have an iPhone 13, it is not the same as your iPhone 13. Even though they are the same model and the same style, an iPhone that belongs to me has been inscribed with the label of my ownership. But the non-fungible nature of this material is not easy to find, but artwork because of its inherent rare properties was the first large-scale application to the NFT field, a single OpenSea trading platform daily turnover of $ 20 million, with a peak of $ 470 million in single-day transactions.

If the field of digital artwork is just a start for NFT, then technically people can create any item in the new world through NFT in the future.

4 Socialization
After having economy and material goods, what people need is " lifestyles", as the main theme of the new era, socialization is an essential part of people's lives.

Based on the transparency and traceability of blockchain, all the activities on the chain will be completely public, so when someone clicks on the virtual image of you or visits your wallet address, he will know what kind of a person you are. You don't need to introduce yourself with beautiful language, and others don't need to consider whether to believe it or not. For example, now where you have been involved in the development and governance of a project, how many digital artworks in your wallet, how many transactions you have made with people, all these can be imagined as your experience value, and become part of your Web 3.0 identity through the blockchain, allowing others to understand you better.

Of course, the problem is that your wealth may consist of many parts, such as monetary wealth, project experience, collections, etc. Many people do not want to show their capital, or many collectors do not want to show all their collections, so this also gives rise to another demand - the demand for privacy, which is to give users a choice of The right to disclose or not - but not the right to tamper. It still guarantees that the information made public is true and cannot be tampered with.

5 Entertainment
If the previous 4 elements solve the basic needs in the virtual world, then entertainment demand is the last part of this puzzle. When people are no longer satisfied with the boring life, games, music and creation become the main theme, and the entertainment products on the chain will actually improve or solve part of the problems that exist in the real world, such as

Games will no longer be a one-way consumption

Music album revenue will flow mostly to the creators

Artists can open digital exhibitions in the on-chain space

……….

All these are waiting to be created by the fellow travelers of this pioneering journey.
