With the rise of the metauniverse, Web3.0 has become a hot word for major manufacturers and investors. Yao Qian, Director of the Science and Technology Supervision Bureau of the China Securities Regulatory Commission, recently published an article, "Web3.0 is a new generation of Internet that is gradually approaching", pointing out that the Internet is at an important point in the evolution from Web2.0 to Web3.0. Strengthening the forward-looking research and strategic prediction of Web3.0 is undoubtedly of great significance to China's future Internet infrastructure construction.

What is web3.0? What is the difference from web2.0?

Web 3.0 is considered as the next generation Internet. On the basis of Web 2.0, Web 3.0 returns to the original intention of Internet open source and decentralization through various blockchain technologies, and builds a user led and decentralized network ecosystem. Web3.0 is very different from Web2.0 in terms of trust mode, governance mode, content, storage, etc.

What technologies does Web3.0 mainly include?

The overall architecture of Web3.0 technology application can be divided into infrastructure layer, component layer and application layer.

Infrastructure layer Like building the foundation of a building, it mainly includes blockchain, distributed storage, computing network, etc;

Component layer Similar to the general materials required for building houses and decoration, it includes the issuance and circulation of token based on the blockchain platform, digital asset management, digital identity, digital wallet, distributed finance and other components, providing customized modular solutions for digital asset transactions, application ecological construction, data security protection, and application interoperability, which is the core part of the overall architecture;

application layer It is equivalent to various places of work and life in the building, built on distributed infrastructure and composable components, and constantly enriched application ecology to meet the new needs of the next generation Internet.

What are the main applications of Web3.0?

From the current development of web3.0, DAO, NFT, DeFi, GameFi and other applications have developed rapidly.

1.DAO

DAO, namely decentralized autonomous organization, is an organization represented by open and transparent computer code, which is controlled by organization members. Financial transaction records and program rules of DAO are stored in the blockchain. Traditional organizations need high trust among members at different levels. The core rules and governance of DAO are handled by smart contracts.

2.NFT

NFT, namely non homogenous token, is an asset digitalization method based on blockchain technology. NFT aims to technically guarantee the authenticity, ownership and transferability of digital goods in view of the pain points of digital assets that are easy to be infringed.

3.DeFi

DeFi, namely decentralized finance, provides decentralized, point-to-point financial services for users by replacing the necessary intermediaries in traditional finance such as banks and brokerage companies through smart contracts deployed on open blockchains such as Ethereum. Starting from Bitcoin, DeFi has developed a variety of traditional financial services, including stable currency, exchange, lending, derivatives investment, insurance, asset management, etc., with the help of smart contracts and modular composability.

4.GameFi

GameFi, namely "Game+DeFi", refers to a blockchain game that introduces DeFi mode and tools. "Making money while playing" is the result of game companies handing over the production right of game resources to players. In traditional games, game production teams master game resources and sell scarce resources as a profit point. In open economy games, players can trade part of game resources and make profits by producing resources.
