What is Web3.0 and why is MetaVerse so popular?

beginning

Hello everyone, I’m Peter , today is the first working day of the new year, so let’s talk about dry goods, Web3 and Metaverse yuan universe

What was before Web3?

web3 was previously web1 and web2 , which is certainly not nonsense.

Web1.0 era

The products of each era are more representative. The representative product of the 1.0 era should be the UC browser in China. This product was very successful at that time. It was mainly used as a mobile browser to display: . The content that shocked users and attracted users Click Browse.

Users in the 1.0 era, the user groups are more passive consumers. For example, as we often joked, you should go to work UC Shock Department. Then create a variety of content that shocks users, and attract users to click and browse to read

Products in the 1.0 era are mainly static content display.

Web2.0 era

In the 2.0 era, the representative products include TikTok, Youtube, Douyin, Connotation Duanzi, etc. In this era, interaction is emphasized, user-generated content is uploaded to the platform, and social media development is promoted. Users have changed from 1.0 passive consumption content to active content. Content creation communicator.

For products in the 2.0 era, users actively participate in content contributions and promote dissemination. The product development company is more of an intermediary role, responsible for unified scheduling and processing

But the problem with 2.0 is also very obvious. For example, when we sell goods on a certain platform, because we need various infrastructures of a certain platform, the platform must be commissioned, and we must abide by his rules, centralized data storage management and control, you can can be tampered with. We may not know it. The fatal disadvantage of 161d3bf47c74bb 2.0 is that it does not reflect the value of users.

But these are not the reasons why all applications need to switch to the web3 scene, and you can continue to use web2 applications without switching. There is a high probability that you will have to wait a long, long time in China, and you may not use web3. (The details will be discussed below)

Next we will focus on Web3

Web3

First of all, Musk has dissed web3 many times on Twitter, and the world’s richest man has already followed

Some companies, including Reddit and Discord, have explored integrating Web3 technology into their platforms by the end of 2021. After users strongly objected, Discord later announced that they had no plans to integrate these technologies

Everything has two sides. When we see that the richest man says it is not good, we have to dig deeper into the goodness of web3. This is my mode of thinking. Once there are things that many people strongly oppose, I will dig deeper into its advantages. Once there is something that many people praise vigorously, I will understand its disadvantages.

So what exactly is web3?

Introduction of Baidu Baike:

Web3.0 is an Internet method developed on the basis of web2.0 that can better reflect the labor value of netizens and achieve a balanced distribution of value.

In general, web3.0 is more than just a technological innovation. Instead, it uses a unified communication protocol to provide users with a more personalized customization of Internet information through a more concise way of technical integration. It will be a key step in the development of the Internet from technological innovation to user concept innovation.

As some things related to the blockchain are very sensitive in China, we can see that Baidu Baike also writes very obscurely.

As I understand it, web3 is a concept. The main realization can be divided into the following points:

1. The introduction of a decentralized mechanism based on web2.0, domain names, distributed data storage, distributed content storage, etc., all of which are based on a reliable blockchain, cannot be forged, all traceable, and data cannot be lost. For example, the current IPFS , ensuser , the Ethereum main chain has solved these problems

2. On the premise of the first point, solve the core problem of 2.0: highlight the labor value of users. For example, if you help others by answering questions on the Internet, your wallet will receive the corresponding amount of coins. Withdrawal and transfer at any time

3. The content is sensitive, and the direct screenshots of Baidu Baike are mainly virtual assets that are recognized and listed on the chain. Similar to NFT, no loss, no tampering, anti-counterfeiting, and cashable

web3 is mainly an innovation of ideas, highlighting the labor value of users. All this must be based on blockchain technology

Since today’s main topic is not about the principles of blockchain technology, we can focus on it next time

The main technologies currently used in Web3:

Technology based on web2.0 plus: solidity, cryptography, blockchain principle, wallet concept, NFT concept, distributed storage ( IPFS , interplanetary file system InterPlanetary File System ), http3.0, etc. I don’t use other technologies temporarily, if you have anything to add, you can add it in the message area

Metaverse?

Recently, the same concept Metaverse , the meta universe is very popular

Facebook changed its name to Meta. Directly stud meta universe, don't patronize the jokes, the traditional domestic Internet, the e-commerce dividend period has passed. However, unlike what some bloggers are talking about, Metaverse focuses on 3D animation, 3D games, etc., because these technologies can now be implemented very well.

The core point of the meta universe lies in the hardware. I bought VR glasses during college, so I have a better say. In addition, at the end of 21st year, our company’s annual tour, our department went to Hengqin, Zhuhai


At that time, a whole four-story VR game could be played. This trip made me believe in the future of the meta universe. The prototype of the meta universe is a VR game, but how to make users have a real experience?

I think there are several possibilities:

1. VR glasses + equipment

2. Brain-computer interface

The VR Experience Hall in Hengqin, Zhuhai used the first VR glasses + equipment to let us experience the feeling of driving a motorcycle through a rainforest night. I almost vomited at the time. It was too real.

There is also the use of VR glasses + roller coaster to simulate the feeling of flying in the sky in the virtual world

Use VR glasses + seat to simulate the feeling of sitting in a tank and fighting

All of this is based on hardware, and software technology is currently not the focus.

The meta-universe as I understand it is based on Web3. There can be a simulation world that allows us to be on the scene and earn income. For example, a scenario: The driver can use VR glasses + supporting equipment + 5G transmission at home to help car owners who have drunk driving on the spot, using the blockchain transfer function, and the money will be automatically transferred to the wallet after completion.

We work in a virtual world and earn profits. Money will be automatically transferred to the wallet

etc...

Why do you want to engage in meta universe?

Because the population growth rate is limited, more novel things must be built to attract people to participate in order to run faster, and the traditional Internet growth is weak. China is already engaged in NFT, although it is cracking down on virtual currencies, but this is a positive sign

Finally added

Since the classmates are pure front-end engineers and have not fully participated in the front-end and back-end architecture design of a project, I will add a comparison chart of web2.0 and 3.0 architecture:

• 3.0

• 2.0

Students who feel interested can continue to study in depth: the concept of DAPP~

At last

Currently in Web3.0, I dare not say that it is very authoritative. Moreover, 3.0 is not well controlled, and there is a high probability that there will be no major development in China. However, you must have an understanding of the technological concepts that are at the forefront of the world.

The above is all the content of this sharing. I think it is helpful to you. Please help me to watch/like/repost. front-end pinnacle official account will occasionally share international cutting-edge technical concepts
