The key is web1 -- the Internet technology that everyone knows and loves. Then came web2- the customer-generated Internet, which meant the arrival of social networking. Right now, no matter what we're looking at from a distance, everyone is talking about web3(and sometimes, web3.0)- the next major evolution of big data. But what is it?

There are different views on the matter. Web3 is currently a work in progress and is not yet fully defined. However, the key principle is undoubtedly decentralised - it will not be manipulated by states and corporations as the web is today - and it is closely linked, to a degree, to the idea of a "meta-universe".

It wasn't until a few years ago that we started -- just to prevent confusion -- to mention the technical term "web3." "0" is also commonly used to describe what is now known as the "semantic Web." This was the original "father of the Internet", TimBerners-Lee, for the device-to-machine network. Knowledge is defined by its primary use, and the word is now more frequently used to describe other things. However, Berners-Lee's definition is known as part of web3, although it is not all of it.

What is a decentralized network?

First, let's talk about blockchain technology. Today, all of the infrastructure for video wechat groups on websites is generally owned by companies, and this infrastructure is manipulated to some extent by policies and regulations set by the state. Mainly because it's the most efficient way to build a network infrastructure -- some people pay to assemble a web server, set up an app on it that needs to be accessed online, and then we either charge people for it or try it for free because we follow his standards.

Today, everyone has other options, especially blockchain technology. Blockchain is a relatively new way of online data storage, which is built around the two core ideas of data encryption and distributed storage.

Data encryption means that data stored on the blockchain needs to be viewed by someone who has the right to view it - even if the data is simply stored in a computer belonging to someone else, such as a government department or company.

Distributed storage means that documents are shared between many electronic computers or servers. If a particular group copy is inconsistent with all other copies, the data in that file is invalid. This reinforces another guarantee, which means that no one other than the person manipulating the data can browse or change the data with the approval of the person without the data or all distributed networks.

In general, these concepts mean that data can be stored in such a way that even if they are only stored on company-owned servers, because they are controlled by an enterprise, they can only be under the control of the people who own them. Local government. If they do not confirm that they have the encryption key to the data, users or government authorities can never open or change the data. Even if they shut down and delete their web servers, the data can still be browsed on one of hundreds of other electronic computers. Very clever, isn't it?

Many of the key concepts associated with building the web3 technology infrastructure are open, meaning that it is based primarily on open source projects and does not require approval or licensing.

Distrust means that interaction and payment can be made between two parties without the need to trust a third party. This does not have to happen in web2 or the version numbers below, as you must be aware that the people you use to interact or buy and sell mainstream media do not control your communication.

A good example of a web3 trust transaction is to send the BTC to another person immediately, rather than through an online trading center or a wallet stored on a central server. The entire transaction process is operated by blockchain algorithms and data encryption, and the probability of almost anyone interfering with it and disrupting it is zero.

Similarly, "no permission required" means that either party to a sale or interaction must seek the approval of a third party, such as a service provider or a government department, before it can occur.

Oh, and if you think all the talk about preventing government intervention sounds a bit anarchic or libertarian, you're not alone! There are still big questions about the safe, reasonable, legal implications of this lack of regulation or control that must be answered. I see government departments trying to enact laws that allow them to manipulate communications and interactions on the Internet to a certain extent. This includes UK government departments' expectations about the ability of standard Chinese citizens to push end-to-end encrypted messages.

Web3 defines -- DAO

Decentralized Autonomous Organization (DAO) This is a web3 definition that describes how a team, company, or group is governed by rules and regulations numbered to a blockchain. For example, according to the DAO store, the prices of all products and details of who will receive payment from the business will also be stored on the blockchain. DAO shareholders will be able to vote online to change prices or from whom they get their money.

However, others cannot change the standards without consent. And the owner of the physical infrastructure, such as the user of the web server or the user of the facility where the profits are stored, cannot intervene in various ways, such as bringing in profits!

In theory, DAOs completely avoid the need for "intermediaries" that most business organizations need, such as financiers, teachers, accountants, landlords, etc.

Artificial intelligence technology (AI) and Web3.0

Most people think that artificial intelligence technology will play an important role in web3. This is because many web3 applications must participate in many machine communications and decision-making processes.

How do you match the metaverse to web3?

The final key concept for web3 is metaverse, which we should have included. For web3, the term "metaverse" includes the next iteration of the Internet's technological front end - the operational interface through which we can interact with the online world, communicate with other users and control data.

Just in case you missed every hot spot, the idea of a meta-universe that will become a more immersive, socially interactive and sustainable version of the Web is well known and favored. It will use virtual reality (VR) and augmented reality (AR) to attract new technologies that allow us to interact with the digital realm in a more real and personal way -- for example, by using virtual hands to pick up and control objects, and listening to me give commands for devices or communicate with others. In many ways, the metaverse can be described as an interface for humans to interact with web3 tool applications.

The possibility of building web3 applications does not involve the metacomes - BTC is one example - but it is widely believed that the technology and feel of the metacomes will play an important role in how many applications interact with our daily lives.

All of this sounds good, and everyone has to love it, right?

Well, not really. It should be mentioned that there has been a lot of high-profile criticism of web3. ElonMusk posted several comments, including suggesting it "seems more like a marketing buzzword than reality right now" and tweeting, "Has anyone seen web3? Can't find it."

In addition, former TwitterCEO JackDorsey doubts that it will be completely free and open, as many expect. He said, "You don't have web3. Both the VC and his LP. It will never escape his encouragement. Ultimately, this is a discrete physical line with different labels.

Others don't like many of the web3 proposals at this stage because they are based on blockchains, which sometimes consume a lot of energy, leading to carbon emissions and climate issues. For example, the BTC blockchain is likely to consume roughly the same amount of electricity and energy as Finland. Other blockchains -- like blockchain, which optimizes algorithms based on proof of equity rather than proof of work -- are not as energy-intensive.
