This year's "Double 11", we can see more and more virtual anchors and digital people emerging on major e-commerce platforms and live broadcast rooms. Many domestic and foreign brands have also entered the NFT field and launched digital collections, trying to provide consumers Open a new metaverse marketing experience in the Web3.0 era.
Currently, "Metaverse" and "Web 3.0" complement each other and are always discussed together. In our previous tweets, we gave you an in-depth interpretation of the Metaverse. So how much do you know about the "good friend" of the Metaverse - "Web3.0"? What are the internal connections between it and the digital people, Metaverse, blockchain, and NFT that frequently appear in the news? This article starts from the concept, development trend, core technology and other aspects, and chats with you about Web3.0.
Before Web3.0
Before entering the topic of Web3.0, let's trace back the development process of the Internet and learn about the "front wave" of Web3.0: Web1.0 and Web2.0.
Web 1.0: Online and Sharing of Information
The rise of Web1.0 benefits from the emergence and application of PC terminals and networks. The Web 1.0 era is full of technological innovations. This is an era in which all heroes rise together. Many portals, chat software, BBS, and e-commerce platforms have emerged during this period, such as the well-known Sina, Sohu, Netease, Tencent, and Alibaba. etc. are Internet companies that have grown up in the Web 1.0 era.
The biggest feature of the Web 1.0 era is the online and sharing of information. In the past, scenes such as reading books, reading newspapers, shopping and socializing have gradually migrated online, and users can search and browse information on the web. But Web1.0 is also called "read-only Web" . The web pages in this period are mainly static read-only versions. poor.
Web2.0: Mobile Internet and Big Data
Compared with Web1.0, which can only be read, the biggest feature of Web2.0 is "readable and writable" . Qzone, Weibo, Douyin, etc. are all representative products of the Web 2.0 era. It is no longer like the Web1.0 era where the platform can only transmit information to users in one direction. The Web2.0 era has seen the gradual popularization of the mobile Internet. Users are always "online" through their smartphones, and can independently create and decorate their own exclusive homepages on the Internet. Share what you think, see and hear anytime, anywhere.
In the Web2.0 era, the number of Internet users is large, and users spend a long time online. A large number of UGC and PGC content are generated accordingly, and the data is growing explosively. In order to improve the distribution efficiency of information content, the intelligent recommendation algorithm based on big data mining has been deeply developed during this period. A very typical case is that Toutiao has made a strong breakthrough in the Web2. The information client giant's surpassing.
Rise of Web3.0
While promoting a smarter, more convenient life and a rapid increase in social productivity, Web2.0 has also exposed its drawbacks. For example, the traffic is gradually monopolized by Internet giants, and the data is in the hands of the platform. Once an application stops serving or its server is attacked, the user's account and the large amount of UGC/PGC content produced will no longer exist. In addition, although users' clicks, browsing behaviors, and the content they create are the traffic sources for the platform to achieve commercial realization, but users cannot get their due rewards from the platform's huge income.
These characteristics of the Web 2.0 era make people expect and imagine a new Internet that is more transparent, fairer, more open, and more decentralized. With these beautiful imaginations of people, Web3.0 came into being.
The term "Web 3.0" was coined in 2014 by Gavin Wood, the co-founder of Ethereum. As the next iterative direction of the Internet, Web3.0 intends to solve the ecological imbalance and opaque development brought about by Web2.0. Web3.0 emphasizes "decentralization". Based on the "readable and writable" feature of Web2.0, Web3.0 also has attributes such as "owning" and "confirming rights". On Web3.0, users have complete control over the content they create, and can distribute value through the agreement they agree with, breaking the monopoly of the platform.
Understand the essence of Web3.0 from the technical principle
From the naming source of Web3.0 just mentioned, we can see that there is a close relationship between Web3.0 and blockchain. The blockchain is the infrastructure of Web 3.0, and the development and application of technologies such as smart contracts and DAOs related to the blockchain are catalysts for accelerating the arrival of the Web 3.0 era. Next, we will further understand Web3.0 through the interpretation of related technologies.
How does Web3.0 achieve decentralization?
- Blockchain
The first thing I have to mention is the blockchain. Blockchain (Blockchain) is a new type of decentralized protocol and the core technology for realizing Web3.0. As a distributed database system (also often referred to as a "distributed ledger"), the blockchain can store data securely, and the information cannot be forged and tampered with, and can automatically execute smart contracts without any audit by a centralized organization. Blockchain can be divided into public chain and private chain. The public chain refers to the consensus blockchain that anyone in the world can read and send transactions and can obtain effective confirmation. The Ethereum mentioned just now is a kind of public chain. .
It can be said that the application of blockchain technology has greatly reduced the cost of trust, and even redefined the property rights distribution system in the Internet era. In the Web 2.0 era, the content and data generated by users are owned by the platform, and the platform has the right to distribute the content value. In the Web3.0 era, the data rights confirmation and authorization mechanism based on blockchain technology will change this situation: users have the right to use and own their own data assets, and can determine the income distribution of the content they create according to the agreement they agree to. ; The acquisition of user data by the website or platform must obtain the user's permission, and everything is no longer centered on the platform, but user-centered, thus forming a decentralized pattern.
In the era of Web3.0, how to confirm the rights of data assets?
- digital wallet
So on the blockchain, how are data assets confirmed and authorized? This has to mention the concept of "digital wallet". A digital wallet is more like a user's unique identity in the online world. In the blockchain, each user has a corresponding account address, which records all the digital assets of the user , such as the digital tokens held, NFT, etc., only the key (private key) of the account Only then can the assets be consumed.

It can be seen that the digital wallet here is not a "wallet" in the traditional sense, but a tool for generating, storing, managing private keys and signing. It does not save assets by itself, but assets are recorded and stored on the blockchain. |
On Web3.0, users no longer need to register accounts on different platforms. They only need to authorize through digital wallets, and they can shuttle between different platforms, experience rich Internet applications, or use digital wallets for consumption and purchase. Like goods (physical goods or digital goods), trade on Web3.0.

It is worth mentioning that building a "unique identity for the entire network" through digital wallets is currently only a very idealized vision. Since different blockchains are independent of each other, the user's account address on each chain is actually different. At present, some researchers in the industry are working on realizing cross-chain communication and cross-chain transactions, but there is still a long way to go to solve this problem. |
Typical digital applications in the Web 3.0 era
——NFT
Among all kinds of digital goods/assets, NFT is the most popular one at present. The full name of NFT is Non-Fungible Token, a non-homogeneous token, and its essence is a digital asset issued on the blockchain, such as game props, digital artwork, tickets, etc. NFT provides a way to mark the ownership of native digital assets. It is unique and non-replicable, has natural collection attributes, and is easy to trade. It is a digital application direction that many companies have already tried, and digital virtual people . Together, it greatly enriches the user experience in the Web3.0 era .

Corresponding to the non-homogeneous token NFT, the "homogeneous token" is similar to the currency we usually use for transactions. The currency of the same denomination represents the same value; while the "non-homogeneous currency" although Its production cost is the same, but the value/price of different non-homogeneous currencies will vary due to subjective judgments. |
Through the above introduction to Web3.0 and core technologies, we can see that Web3.0 is more like a beautiful concept and vision. It is an innovation of the existing Internet operating system and strives to build a more democratic Internet. . The structure and operation of the Metaverse are based on Web3.0, complementing each other with Web3.0, and jointly depicting the blueprint of the future Internet life for us
