First of all, what is the web?
The full name of the web is the World Wide Web, which is the global wide area network, also known as the World Wide Web .
This network connecting the world has not always been what we see now, but has undergone continuous evolution for decades.
Before 2000, the Internet we could see was mainly portal websites . For example, news and entertainment websites such as Sohu, Sina, and Netease.
When visiting these websites, what we can do is mainly to passively read the content inside, with little opportunity to interact and create our own data.
With the passage of time, Internet technology is also constantly updated. With the launch of social networks such as Facebook and Weibo, users can freely publish their own content; with the launch of QQ and WeChat, people have realized instant messaging.
In the video era, users have more ways to interact. You can add interesting bullet screens to videos, and even publish various short videos by yourself, or broadcast live online, so that you can become self-media one by one.
web2.0 looks very good, but it still has some shortcomings.
On the one hand, on various web 2.0 network platforms, users create a large amount of data, but these data are owned by Internet companies. Internet companies can delete these data at will, and can also use these user data to obtain huge benefits.
On the other hand, no matter how the platform is presented, it is operated by the company behind it. Once the company collapses, the platform will also be closed.
It can be said that web2.0 users can neither own data nor own platform.
In 2008, a person named Satoshi Nakamoto first proposed the concept of blockchain . Subsequently, Bitcoin, an open source project based on the blockchain concept, was launched.
The so-called blockchain is a chain composed of one block after another. Each block stores certain information and is connected into a chain according to the time sequence of their generation. The data of this chain is not stored in a centralized manner, but is stored in scattered server nodes around the world.
As for Bitcoin, it is the earliest digital encrypted currency in the world. It uses blockchain technology as its core and realizes features such as distributed bookkeeping and anonymous transactions.
The influence gained by Bitcoin has shown people that the Internet can still play like this! As a result, a large number of projects based on blockchain technology were born.
The core of the blockchain project is decentralization , allowing everyone to become the common owner of the project. Based on this concept, a brand-new organizational form was born, called Decentralized Autonomous Organization ( DAO for short) .
In the past two years, people have made some bold innovations based on the blockchain, such as non-homogeneous tokens (NFT) . This type of digital asset is not used in Bitcoin, and each one is unique.

Another example is Metaverse , which received widespread attention last year. This is a highly free digital world with an independent economic system in which users can participate and create the entire world together.

web3.0 is a new stage of Internet development. Its biggest feature is based on blockchain technology, realizing the Internet model of decentralization and co-construction by users .
