Web3.0, but few people can clearly explain what is Web3.0. I try to explain Web3.0 in popular language. I believe that after reading this article, you can easily answer the following related questions:

What is Web1.0, 2.0, 3.0?

How to understand the semantic network?

Why are AI and IoT always associated with Web3.0?

What is the relationship between Web3.0 and blockchain?

Web1.0: Read

Roughly in 1990-2000, it belongs to the so-called Web1.0 era. Was there internet before this? Yes, the Internet at that time had been running for 20 to 30 years, and it was mainly used in the military industry, scientific research institutions, etc., so the Internet was a technology that came out of laboratories and military bases.

Suffice to say, Web1.0 is a branch of Internet services, and all networked systems are the Internet. Don't get entangled in the concepts of Arpanet, Internet, World Wide Web, HTML, etc., and grasp the core: in the Web1.0 era, you can only read, read or browse, and cannot interact. This kind of information transmission is one-way.

For example, the information in the newspaper is copied to the Internet to form a portal website, such as Sohu, Sina and other portal websites in the early days, the main function is to digitize the paper media, you can see the information, But can't interact.

Web2.0: Read & Write (read-write interaction)

About 2000 Years later, the one-way transmission of information has become two-way or multi-way, adding a function is "write (write)". A little innovation in the underlying architecture can set off huge waves in the application market.

Because of the addition of "interaction", Didi, Meituan, uber, Airbnb broke out , facebook, Tencent and other giant companies. Your likes, comments, and forwarding of this article also belong to the application of Web2.0.

Web3.0: Semantic network (semantic network)

Semantic network, semantic network also It's called semantic web, it feels extremely high-end, and I don't understand it when I look at it. In fact, it is very simple. The concept of this concept is related to Mr. Berners Lee, the inventor of hypertext links. He once said:

"All computers in the network can Analyze data in the network, including content, links, and interactions between people and computers. The Semantic Web will make this possible, and daily transaction mechanisms, transactions, and our daily lives will be handled by machine-to-machine communication The "smart agent" that people have been bragging about for years will finally come true."

I searched for related literature:

The above passage is a general sense.

There are many scholars' articles and ppts about Web3.0 at this address.

Remarks: The literature I can find on Web3.0 and Semantic Web has rushed to 2009-2012, and the concept of blockchain has not been mentioned at that time Come out, so from this point of view, Web3.0 is not equal to blockchain.

Explanation in the vernacular: the semantic network is the machine language network.

After the machines are interconnected, a system (understood as a software system in general) is formed. The machines and devices in this system can communicate and interact, and classify information.

One-size-fits-all

Okay, after simplifying the semantic network into a machine language network , I understand why IoT (Internet of Things) is associated with Web3.0, because the Internet of Everything itself is a result of machine language intercommunication.

And AI (artificial intelligence) is also the result of machine language interaction to a certain extent. In the above picture, it is said that "the system is easier to understand and classify information than humans." The "classification" here actually has an important concept behind it called "knowledge graph". One of the core points of the way machine language understands "semantics" in the Web3.0 era is: knowledge graphs. The related, categorized systematized information is called "knowledge". Therefore, when you read an article explaining Web3.0, see if it explains knowledge graph and semantic network, and you will know whether this article is worth reading.

Mr. Berners-Lee's machine language or "smart agent" of the system is easy to think of smart contracts. The concept is basically the same, but the implementation path is different. The smart contract refers more to the automated execution program on the blockchain.

Therefore, some people on the Internet say that Web3.0 has added a trust mechanism, and the key word is "verifiable", which is not wrong.

Because machine language logic will not engage in favoritism and fraud, under the blockchain’s token incentives and collaboration network, it can achieve decentralization and pay more for more work . The power of data or knowledge has been taken back from the giant centralized companies in the Web2.0 era and distributed to everyone. The foundation of all this is the maturity of the semantic network. This maturity will promote the evolution and maturity of collaboration methods, which is why blockchain is an important cornerstone of Web3.0. Blockchain is an important footnote of Semantic Web.

Essentially speaking, Web3.0 is the process of expanding the functions of machines and changing power from centralization to decentralization. This process looks very "blockchain", so people in the blockchain industry are excited, so there is a saying "blockchain=Web3.0".

Of course, the blockchain will play a very important role in Web3. Peer-to-peer currency systems (such as BTC), smart contracts (such as ETH contracts), distributed storage (such as Filecoin), cross-chain networks (such as Polkadot), Dex (such as Uniswap), the scribbled strokes at the beginning cannot cover up the essence of the whole picture. grand.

This article is 1600 words, almost no illustrations, involving Web1.0, web2.0, web3.0, semantic network, Internet of things, artificial intelligence, knowledge map, Conceptual knowledge such as blockchain.
