After all, the concept is somewhat similar to Bitcoin. I can always come across this thing when I play on my mobile phone. After reading a lot, I feel like I know something about it, but I don’t know what it is. It’s very abstract.
Web3 - the emerging term for the centralized web
Since 2015, Joseph Lubin, founder and CEO of ConsenSys, has been speaking, writing, and funding teams to Building Web3 and the decentralized web. The Web3 philosophy is the touchstone that guides all early investments and projects at ConsenSys. MetaMask is currently the main way for individual users to access the Ethereum blockchain. Of course, there are many other Ethereum-compatible networks. It's a way to securely generate a public key on your phone or computer, but it uses new guidelines for online interaction - only you have access to your account and data, and you can choose what can be shared and what data remains Private. Some people also compare MetaMask to an encrypted version of the consent manager.
With the development of blockchain technology, Web3 technology has gradually attracted people's attention. Web3 technology is an extension and supplement of blockchain technology in Web applications. It will change the pattern of the entire Internet and bring a new experience different from the existing Web2.0 era.
Web3 technology adopts a distributed storage model and takes decentralization as the core concept to make data more secure, reliable and non-tamperable. The biggest feature of this technology is that it can achieve point-to-point communication, getting rid of some inconveniences caused by centralized architecture, so that users and data are no longer restricted and controlled.
Web3 technology can not only solve many problems existing in the current traditional Internet, but also lay the foundation for a new Internet ecosystem. For example, distributed applications (DAPP) based on Web3 technology can interact directly with users without going through a third-party platform. At the same time, user data is also stored directly locally, which greatly improves the level of privacy and security protection.
Web3 technology also has the characteristics of autonomy and autonomy, and can provide better services for the future digital economy and social governance.

What is Web1.0?
Web1.0 is just an era of information senders and query information.
This is an era when the World Wide Web (World Wide Web) is popularized, and individuals can create websites and spread information. And text websites based on HTML are the mainstream, with less picture and video content, and email is the main communication method. And two-way communication between message sender and audience is almost impossible.
What is Web 2.0?
Web2 is an era in which users become more free to use the Internet, and two-way communication between information senders and viewers becomes possible. Today, Web2.0 has replaced Web1.0. A characteristic of Web2.0 is the spread of SNS such as Twitter, YouTube, Facebook and Instagram, which can also be said to be the modern Internet.
Anyone can easily become a communicator, and sharing of image and video content becomes even easier. Web 2.0 makes it easy to get the information you want and connect with many people. Web 2.0 is characterized by centralized services, that is, the history and other information provided by creators are concentrated in specific companies that provide services, such as Google and Twitter.
So some people pointed out that because information is concentrated in one place, there are security risks caused by cyber attacks, and problems such as personal information privacy being monopolized by large companies.
Separation of three powers Web3 (Web3.0)
Web3 (Web3.0) is a decentralized system that is expected to solve the centralization problem of Web 2.0 introduced above. The goal is to decentralize personal power and no longer be monopolized by the 5 major GAFAM companies (Google, Amazon, Facebook, Apple, Microsoft).
Blockchain technology makes this distribution possible. This is a technology currently widely used in cryptocurrencies such as Bitcoin and Ethereum. By applying it widely to the Internet world, the problems of Web2.0 are thought to be solved.
Simply put, blockchain technology is a technology that correctly records transaction data on the Internet. In services using blockchain, transaction information is shared among multiple users.
If data is tampered with, copied or illegally accessed somewhere, the fraud will be detected immediately because it is different from other users. In other words, it is possible to set up a system where users check each other's data over the network.
By utilizing blockchain technology with this characteristic, Web3.0 will reduce privacy issues and information leak risks caused by personal information owned by specific companies owned by Web2.0.
What is blockchain?
Blockchain is a distributed ledger technology that stores transaction records on multiple computer nodes and uses powerful encryption algorithms to ensure data security and non-tamperability.
